The local device is connected to the automotive controller and is wirelessly connected to the client device. The client device is connected to the technician device through a system server. Programming configurations, including firmware, settings, and parameter updates, are selected from a technician device, sent to the system server, and uploaded to local device using J2534 communication protocol. The client device receives reprogramming data from the system server and sends the reprogramming data to the local device.

Description

BACKGROUND

An engine control unit or an “ECU” is a widely used type of electronic controller that monitors sensor output and controls a series of actuators on an internal combustion engine to ensure optimal engine performance. It does this by reading values of a multitude of sensors in the vehicle and storing and interpreting the data it receives using data structures, such as lookup tables. These lookup tables may be used to monitor the accuracy of the sensors or to adjust engine actuators appropriately.

The ECU monitors various sensors on the automobile such as the odometer and sensors for oxygen level, coolant temperature, mass air flow, air intake temperature, crank shaft angle, throttle position, cam shaft angle, and engine knock. Communicated packets include information from the odometer, while lookup tables provide feedback information for adjustment and control of ignition timing, cam shaft position, fuel injector input, fuel pump input, fuel pump pressure, cooling fan speed, admission control systems, forced air induction controls, traction controls, and transmission gear selections. In many situations, ECUs also send error codes to the vehicle dashboard to indicate immediate problems, such as overheating, or maintenance requirements, like oil changes. In some cases, the error codes activate warning lights which are deactivated after repair.

Certain classes of ECUs are programmable. Modern ECUs incorporate a microprocessor which can process inputs from engine sensors in real time. The microprocessor stores its programming in memory or e-proms attached to the CPU of the microprocessor.

Programmable ECUs are used, for example, where significant aftermarket performance enhancing modifications have been made. Such modifications often include the addition of a turbo charger, intercooler or modified exhaust system. Programmable ECU's are also used for several vehicle systems, such as engine control module (ECM), transmission control module (TCM), body control module, anti-lock brake system (ABS), airbag control module, and so on, that each receive routine updates from the manufacturer of the vehicle. Each ECU is remapped or reprogrammed to adapt the performance of the involved system to match the required modifications and/or to update the software and parameters of the ECU. Other changes for high performance engines which can be remapped or reprogrammed in an ECU include ignition position, timing, RPM, coolant temperature, transient fueling, low fuel pressure modifiers and a closed loop lambda (in order to modify a target air/fuel ratio), turbo charger waste gate control, staged fuel injection, variable cam timing, gear control, and turbo charger anti-lag.

The ECU may be integrated and synchronized with one or more additional electronic devices to perform one or more additional functions. One such device is the electronic logging device (ELD), which may be used together with the ECU to record driving time, for easier, more accurate hours of service (HOS) recording.

Vehicle manufacturers utilize a number of different communications protocols for diagnosing and reprogramming a vehicle's ECU. Until recent years a different diagnostic/service device was required for each communication protocol. As a result, third-party automotive technicians would either need to have a device for every communication protocol in order to service all vehicles, or turn away clientele. In 2002 the Society of Automotive Engineers (SAE) developed the J2534 standard in an effort to standardize aftermarket emissions related services, and comply with EPA, California Air Resources Board (CARE) mandates geared towards reducing harmful emissions.

The SAE J2534 standard allows for aftermarket flash re-programming of emissions related modules (ECM/TCM). J2534 standard requires a compliant J2534 hardware device with SAE J1962 OBDII connector, J2534 Application and DLL file, and a J2534 compliant OEM API. The standard utilizes a number of universal communication functions that allow a computer to communicate with any vehicle ECU regardless of the communications protocol used by the vehicle, such as: PassThruConnect; PassThruDisconnect; PassThruReadMsgs; PassThruWriteMsgs; PassThruStartPeriodicMsg; PassThruStopPeriodicMsg; PassThruStartMsgFilter; PassThruStopMsgFilter; PassThuSetProgrammingVoltage; PassThruReadVersion; PassThruGetLastError; and PassThruloctl. The communication protocols supported by the J2534 standard are; ISO9141, ISO14230 (KWP2000), J1850, CAN (ISO11898), ISO15765, SAE J2610, and J1939.

DETAILED DESCRIPTION

Referring to FIG. 1, system 100 is provided. System 100 includes system server 102 connected to internet 108 through web server 104. The system server also includes database 106.

Client device 110 is connected through a mobile network to internet 108 and contains application 111. Client device 110 is also connected to local device 112. Local device 112 is a J2534 compliant hardware device and can be fitted with a SAE J1962 OBDII connector. In a preferred embodiment the local device establishes a Wi-Fi or Bluetooth connection between the client device and the automobile. Local device 112 is hardwired to an automotive controller, such as vehicle device 114. Vehicle device 114 is connected to sensors 120 and actuators 122 resident on the vehicle. The sensors and actuators communicate with the onboard controller through a CAN BUS (also known as a controller area network (CAN) bus) as is known in the art.

Client device 110, acts as a client of system server 102, and as a client of local device 112. Embodiments of client device 110 include any handheld wireless device, such as, a smart phone, a tablet computer, a notebook computer, a netbook computer, and so on.

Technician device 124 and third-party device 130 are connected to internet 108 and communicate through the internet to system server 102, and dealer device 116. Technician Device 124 contains J2534 application 126 and OEM API 128. Third-party device 130 contains J2534 application 132, and OEM API 134. Embodiments of OEM API 128 and 134 include a J2534 compliant vehicle manufacturer application program for the analysis and reprogramming of vehicle device 114. J2534 application 126 and 132 include a J2534 DLL file with J2534 compliant functions and routines for communication between local device 112 and client device 110, technician device 124, and third-party device 130.

Dealer device 116 is also connected to internet 108 and communicates through the internet to technician device 124 and third-party device 130. Dealer device 116 is contains database 117. In a preferred embodiment dealer device 116 stores application files for OEM API 128 and 134. Similarly, calibration writer server 118 is connected through the internet to system server 102 and client device 110.

Referring to FIG. 2A, operation of a preferred embodiment 200 will be described. In use, the device allows recording and viewing of automobile information, diagnostics, automobile updates for onboard computers, and data logging to allow study of driving habits to research fuel economy.

At step 201, the client device opens the application and sets up an account by entering certain demographic information. At step 202, the application uploads the account information to system server 102.

At step 203, the calibration writer server sets up an account through a form served up through the internet from the system server. The calibration writer server includes account information such as name, address, email address, and submit computer Cal/Pid. At step 204, calibration writer server inputs a set of operating system parameters which include programming information and look up tables for the onboard controller. At step 206, the parameters are submitted to system server 102. At step 208, system server 102 stores the parameters and the account implementation. At step 210, the database is updated by the system server with the new parameters and associated with the calibration writer server. At step 212, the system server uploads the parameters to client device 110 via a wireless network.

In an alternative embodiment, a technician downloads the parameters or firmware from calibration writer server 118 via a web browser. The technician then uses system server 102 to download the updated parameters or firmware to client device 110.

At step 214, a client device stores the parameters. At step 215, client device opens an application (or “App”) which displays the parameters and certain options to the user. At step 216, the client device receives options from the user as to which parameters to implement. At step 218, the chosen parameters are uploaded to the local device via a Wi-Fi or Bluetooth connection. At step 220, the local device stores the parameters and initiates certain timing functions such as onboard recording and storage of data.

At step 222, the chosen parameters are uploaded to the vehicle device. Step 222, may further include local device 112 using Socket_CAN, or an open source driver and network stack that is compatible with the vehicle device. For example, vehicle device 114 may be configured to use a communication protocol including, but not limited to, SAE J/1979, SAE 2190, ISO-14230-3, ISO-14229.2006, a CAN protocol, and combinations thereof. Local device 112 is configured to receive communications in a first communication protocol (e.g., JavaScript Object Notation JSON message), and then forward them, or data from them, in the proper communication protocol for vehicle device 114.

At step 224, the vehicle device stores the new parameters and lookup tables. At step 226 the vehicle device implements the new parameters and lookup tables. Step 226 further includes reprogramming or remapping the firmware of the vehicle using a bootfile. Step 226 may also include a check to see if previous updates or programming operations failed. If the updates or operations failed, then a reflash recovery operation is performed. The reflash recovery operation may include sending or re-sending a seed or key for a diagnostics login, getting the failed update file, reading data from the file, downloading a bootfile, erasing a sector, downloading sector data to the appropriate module (e.g., ECM), iterating the erasing and downloading of sector data for multiple sectors of the appropriate module, and resetting the module. Upon completion of the reflash recovery operation, the downloading of the new configuration file and installing of the customer modifications proceeds.

At step 228, the vehicle device generates an acknowledge signal. At step 230, the acknowledge signal is sent to the local device. At step 231, the local device stores the acknowledge signal. At step 232, the local device reports the acknowledge signal to client device 110 via the WiFi or Bluetooth connection. At step 233, the client device stores the acknowledge signal and the App displays the status of the local device and the uploaded parameters.

Referring to FIG. 2B, an alternate preferred embodiment 238 is described. At step 243, the client device requests a target for a feed of live data from the vehicle device. Step 244, the client device transmits the upload request to the local device. At step 245, the local device stores live data request. At step 248, the local device sends a request for live data to vehicle device 114. At step 250, the vehicle device uploads the system status from the automobile to the local device. At step 252, the system status is sent to the local device. At step 256, the local device stores the system status. At step 258, the local device uploads the system status to client device 110. At step 260, client device stores the system status. At step 261, the local device enters a loop to repeatedly request system status (“live data”) from the vehicle device. At step 262, the App displays the system status. The display is refreshed as updated system status is received from the local device.

At step 263, client device 110 chooses an option on the application to clear error codes. At step 264, the request is uploaded to the local device. At step 265, the request is stored in memory on the local device. At step 266, the request is uploaded to the vehicle device. At step 267, the vehicle device acknowledges the request and clears the error code.

At step 268, the client device chooses an option on the application to request a diagnostic report. At step 269, the request is uploaded to the local device. At step 270, the local device stores the request. At step 271, the local device uploads the request to the vehicle device. At step 272, the vehicle device generates the diagnostic report. At step 273, the diagnostic report is sent to the local device. At step 274, the local device stores the diagnostic report, according to date and time, in memory. At step 275, the diagnostic report is sent to the client device. At step 276, the diagnostic report is displayed according to the request of the user.

At step 277, the client device, through use of the application requests a calibration report. At step 278, the calibration request is uploaded to the local device. At step 279, the local device stores the request for calibration. At step 280, the local device forwards the request to the vehicle device. At step 281, the vehicle device accesses the currently stored parameters and the calibration. At step 282, the parameters are sent to the local device. At step 283, the local device stores the current set of parameters according a date and time stamp. At step 284, the local device sends the parameters to the client device. At step 285, the application on the client device displays the requested calibration parameters.

Referring to FIG. 2C, a third embodiment 286 is described. At step 287, client device 110 generates a period request. A period request is a request for a feed of logged data from the vehicle device for a specified period of time via local device 112. The period request for the logged data may be generated from customer client device 110. At step 288, the client device transmits the period request to local device 112. At step 289, local device 112 gathers logged data stored on the device sufficient to fulfill the amount of logged data required for the period request. At step 290, the local device performs a logged data transfer to client device 110.

At step 292, the client device stores and displays the logged data.

Referring to FIG. 3, a schematic map 300 of the setup of system server 102 and certain functions of a preferred embodiment will be described.

System server 102 presents a set of webpages for the various users of the system through web server 104 using a user/password interface. At 302, 304, and 306 a schematic of the local home page is shown. Local home page provides options for a choice of a user type for each of calibration writer server, a dealer, and a customer or “end user.” The database includes records for each vehicle 310 and each computer profile ID number 312. Each vehicle 310 includes vehicle identification number, ECU serial number, make, model, engine, fuel tank number, gear ratio, tire size and vehicle modification categories. Each record is associated with a particular vehicle entered into the system. Computer profile ID number 312 is a database entry including vehicle, calibration, PID configuration, and warning type. Computer profile ID number 312 also includes vehicle options and datalog recordings for each vehicle.

Calibration writers webpage 304 includes forms for entry of a data record for users who input engine control parameters. Each data record includes entries for photos or logos, name, phone, address, start date, email and computer Cal/Pid. When the form is complete, upon entry, system server 102 enters the data from the data form into a record into the database (e.g., logged data). The system server then copies the data record into one or more computer profiles having an ID number. Accordingly, the data records are associated with computer profile ID number 312. All reports generated by the automotive controller at the request of the local device are associated with current calibration of the vehicle when stored in memory. In some embodiments, the data in the record is then copied directly into memory at vehicles 310.

The dealers webpage 306 serves up a form for data entry including data related to photo/logo, name, phone, address, start date and email address. The “dealers” in some embodiments are maintenance shops which service vehicles but do not write calibrations. In other embodiments, the “dealers” include manufacturers or dealerships that write calibrations and service vehicles. For example, a customer may take their vehicle to a manufacturer or dealership for repairs, and may already have access to the web-based application. In this case, the manufacturer or dealership may choose to use, or have the customer use, the web-based application and supply its own calibration files.

The customers webpage 308 includes a form for entry of data including but not limited to, photo, phone number, start date and email address. The web form also enables the customer to request download of an application to be locally installed. The APP GUI provides access to the functions of the local device. In a preferred embodiment, the functions include but are not limited to, requesting a report of a current calibration, requesting a live report of engine status, requesting a diagnosis report, requesting that an error code be cleared, uploading a calibration update from a dealer or manufacturer, volume control, and combinations thereof.

The APP GUI also allows for vehicle modifications. The vehicle modifications may include one or more of: tuning parameters (i.e., a tune) for the vehicle; firmware updates for the vehicle; live vehicle data as received by a controller (e.g., vehicle device 114) of the vehicle; logged vehicle data as stored by local device 112, as stored by system server 102, or as stored by a database of system server 102; diagnostic reports, trouble codes, and parameter IDs; driver's records of duty (RODS); and combinations thereof. The vehicle modifications may be communicated using a communication protocol including, but not limited to, a telematics protocol (e.g., Ethernet, Wi-Fi, Post Office Protocol 3 (POP3), Internet Message Access Protocol (IMAP), Simple Mail Transfer Protocol (SMTP), Hyper Text Transfer Protocol (HTTP), etc.), or a local protocol (e.g., Bluetooth, USB 2.0, infrared, etc.).

Referring to FIGS. 4A and 4B, method 400 updates engine parameters in response to a check engine code (also referred to as a diagnostic trouble code (DTC)) being generated by vehicle device 114. The method includes one or more messages passed between calibration writer server 118, system server 102, client device 110, local device 112, and vehicle device 114.

At step 411, vehicle device 114 generates a check engine code and freezes a frame of data. The check engine code identifies a problem with the vehicle. The frozen data indicates the status of the vehicle at the time when the problem that caused the check engine code to be generated occurred.

At step 412, a data connection is established between local device 112 and vehicle device 114. In one embodiment, the data connection is established by connecting local device 112 to an onboard diagnostics port that is connected to a CAN BUS to which vehicle device 114 is connected.

At step 413, a wireless connection is established between client device 110 and local device 112. In one embodiment, local device 112 acts as a wireless local area network (WLAN) access point to which client device 110 can connect. In establishing the wireless connection, a transmission control protocol (TCP) socket is opened between client device 110 and local device 112 so that data can be passed back and forth between client device 110 and local device 112 using JSON messages.

At step 414, a request for gauge data is sent from client device 110 and is received by local device 112. In one embodiment, the request is sent using JSON using the TCP socket. For each of the one or more gauges displayed by client device 110, a gauge data request is sent. After receiving the request from client device 110 by local device 112, client device 110 is subscribed to and receives notifications from local device 112 that include updated data to be displayed on the gauge associated with the gauge data request.

At step 415, a data request is sent from local device 112 and is received by vehicle device 114.

At step 416, vehicle device 114 retrieves the gauge data. In one embodiment, vehicle device 114 retrieves parameter identifier (PID) data that is associated with the gauge data.

At step 417, the data is sent from vehicle device 114 and is received by local device 112.

Optionally at step 418, local device 112 records the data received from vehicle device 114 in a log file on local device 112.

At step 419, the requested data is sent from local device 112 and is received by client device 110. In one embodiment, client device 110 is subscribed to local device 112 so as to receive a notification from local device 112 each time local device 112 receives updated data from vehicle device 114.

At step 420, the data is displayed by client device 110. The layout settings that describe the “look and feel” of the gauge are stored on client device 110 and the data is displayed in accordance to the layout settings.

At step 421, a request for the engine code, the frozen data, and optionally the log data is sent from client device 110 and is received by local device 112.

At step 422, a request for the engine code and the frozen data is sent from local device 112 and is received by vehicle device 114.

At step 423, vehicle device 114 retrieves the engine code and frozen data that were generated in step 411.

At step 424, the engine code and frozen data are sent from vehicle device 114 and are received by local device 112.

At step 425, the engine code, frozen data, and optional log are sent from local device 112 and are received by client device 110.

At step 426, client device 110 stores the engine code, frozen data, and optional log.

Moving to FIG. 4B, at step 427, client device 110 displays the engine code.

At step 428, the engine code, frozen data, and optional log data is sent from client device 110 and is received by system server 102.

At step 429, a request for updated engine parameters is sent from client device 110 and is received by system server 102.

At step 430, a request for updated engine parameters is sent from system server 102 and is received by calibration writer server 118.

At step 431, updated parameters and/or firmware are sent from calibration writer server 118, and are received by system server 102.

At step 432, the updated parameters and firmware are sent from system server 102 and are received by client device 110.

At step 433, the updated parameters and firmware are stored on client device 110.

At step 434, the technician selects one or more parameters and firmware with which to update the vehicle.

At step 435, the selected parameters and firmware are sent from client device 110 and are received by local device 112. One or more parameters and the firmware may be selected to be updated and are sent.

At step 436, reprogramming instructions are sent from local device 112 and are received by vehicle device 114. In one embodiment, the instructions cause vehicle device 114 to be flashed with the updated firmware when the firmware is selected to be updated. Additionally, parameters can be changed beyond what was included with the updated firmware. The updated firmware may be the latest default firmware from the vehicle manufacturer that does not have every parameter tuned for the specific configuration of the vehicle. In one embodiment, the reprogramming instructions of local device 112 first reflashes vehicle device 114 with the updated firmware and then updates specific engine tuning parameters.

At step 437, vehicle device 114 updates the firmware and parameters to the values received from local device 112.

Referring to FIGS. 5A and 5B, user interface 502 includes menu button 504 on title bar 506, which is above eight gauge view 508. Eight gauge view 508 includes eight (8) mini gauge views 510, 512, 514, 516, 518, 520, 522, and 524.

User interface 502 is displayed on a client device via an app running on the client device. The name, value, and units of each respective mini gauge views 510, 512, 514, 516, 518, 520, 522, and 524 are displayed on user interface 502 on a client device.

The Accelerator Pedal table record is a table that converts an actual accelerator pedal position (as a percentage) and engine RPM to an interpreted accelerator pedal position shown on the “z” axis. For example, when the actual position is 80 percent and the current engine RPM is 1000, then the interpreted position will be 52 percent.

Turning to FIG. 27H, the categories of “TCM [transmission control module] MAPS”, “Shift Points”, and “2-3 Shift” are opened with the leaf node and record “2-3 Up-shift Main” being selected. Information view 2714 indicates that the 2-3 Up-shift Main record is in units of output shaft speed (OSS), has a minimum value of −10, and has a maximum value 5000. The 2-3 Up-shift Main record identifies the shift point threshold based on throttle position and shaft speed when shifting from 2nd gear to 3rd gear. The minimum shift point is with a shaft speed of 575 RPM and the throttle position at 6% and the maximum shift point is with a shaft speed of 1288 RPM and the throttle position at 75%. Outside of these constraints, up shifting from 2nd to 3rd gear will not be performed.

The Press. 2M-1M ONCOMING record is a table that identifies the 2-1 on coming start pressure, which is the starting point for pressure before adaptive changes, and is based on engine RPM and torque (in pound feet). For example, when the RPM is 2250 and the torque is 50 pound feet, then the start pressure is 111 pounds per square inch.

Turning to FIG. 27K, the “TCM MAPS” category is opened with the leaf node and record of “Diagnostics” being selected. Information view 2714 indicates that the Diagnostics record allows for enabling or disabling diagnostic trouble codes (DTCs). Chart view 2712 includes a list of the diagnostic codes that can be enabled or disabled. In a preferred embodiment, selection of one of the diagnostic codes causes information view 2714 to display descriptive information about that diagnostic code.

Referring to FIG. 28, local device 22074 is a system that incorporates several systems, devices, controllers, boards, modules, and interfaces. Local device 22074 includes controller 2802 that runs one or more applications so that local device 22074 can interact with system 22000.

Referring to FIG. 29, a state diagram 2900 of different states of a preferred embodiment of the local device is depicted.

In wait state 2906, the local device is powered up and waits for further input.

Transition 2908 to mode select state 2910 occurs with a user selection of a mode of the local device from a GUI display. Mode select state 2910 includes a Tune Control Mode/function of the local device, as will be further described. Transition 2912 returns the local device to wait state 2906.

Transition 2914 to output control state 2916 includes an Output Control Mode/function of the local device, as will be further described. Transition 2918 returns the local device to wait state 2906.

Transition 2932 to third party proxy control state 2934 includes the third party proxy functions of the local device, as will be further described. Transition 2936 returns the local device to wait state 2906.

Referring now to FIGS. 30A, 30B, 30C and 30D, mode select state 2910, is further described. At step 3002, mode select state 2910 is selected. At step 3004, the local device sends a message to the vehicle controller, confirming the vehicle type. At step 3006, a set time for receiving a response from the vehicle controller is monitored. If a response is not received within the set time, then the local device times out at step 3008 and returns to step 3002. If a response is timely received, then the method proceeds to step 3010. At step 3010, the message from the vehicle controller is masked, including message header, frame parameters, and Serial IDs (SIDs). The SIDs include, but are not limited to, RPMs, gear and transmission parameters (e.g., temperature), ignition key position, throttle position, and coolant temperature.

At step 3012, sufficient memory is reserved for performing the tune modifications. A buffer may be used, or an array of sufficient size is defined, for receiving a SOFT map. At step 3016, PID variables are defined in memory for performing tune modifications.

At step 3018, a CAN configuration file is retrieved from the vehicle controller, which include VIN, year, and ECU and TCU part and serial numbers.

At step 3020, a year of the vehicle is compared to a predetermined year. For example, if the predetermined year is 2012 and the vehicle year is greater than or equal to 2012, then the method moves to step 3022. At step 3022, one or more power levels are retrieved from a JSON message and are used to adjust the ECU and/or the TCU in the vehicle. The method then ends at step 3023. In this example, if the vehicle year is less than 2012, then the method moves to step 3024, as shown in FIG. 30B.

Referring then to FIG. 30B, at step 3024, a SOTF map is read from the calibration file included in the JSON message. Power levels, part numbers, VIN, and serial numbers are also read at step 3024. In a preferred embodiment, the data read at step 3024 is stored in the CPU register using a ring or FIFO buffer.

At step 3026, the data read at step 3024 is checked to ensure it includes an ECU part number. If so, then at step 3027, the ECU part number is stored and the method moves to step 3028. If not, then the method proceeds directly to step 3028.

At step 3028, the data read at step 3024 is checked to ensure it includes an ECU serial number. If so, then at step 3029, the ECU serial number is stored and the method moves to step 3030. If not, then the method proceeds to step 3030.

At step 3030, the data read at step 3024 is checked to ensure it includes a TCU part number. If so, then at step 3031, the TCU part number is stored and the method moves to step 3032. If not, then the method proceeds to step 3032.

At step 3032, the data read at step 3024 is checked to ensure it includes a TCU serial number. If so, then at step 3033, the TCU serial number is stored and the method moves to step 3034. If not, then the method proceeds to step 3034.

At step 3034, the data read at step 3024 is checked to ensure that a VIN is present. If so then at step 3035 the VIN is stored and the method moves to step 3036. If not, then the method moves to step 3036.

At step 3036, the data read at step 3024 is checked to ensure it includes an SID. If not, then at step 3037, an “Error” message is provided and the method ends at step 3038. If so, then the method proceeds to step 3039, as shown in FIG. 30C.

Referring then to FIG. 30C, at step 3039 the ignition status of the vehicle is checked. If it is “ON”, then at step 3040 a “Turn engine off” message is sent to the display and the method returns to step 3039. If the ignition is “OFF”, then at step 3044 a “Turn ignition to ON position” message is sent to the display and the method moves to step 3046.

At step 3046, the vehicle status is determined. The vehicle status indicates if the vehicle is running properly and whether or not there are any outstanding DTCs. If the vehicle is not running properly (i.e., status !=Normal), then at step 3048, the Tune Control mode ends (i.e., no modifications are made) and the system returns to a wait state. Step 3048 may also include sending an error message, to the display. If the vehicle is running properly then the method proceeds to step 3050.

At step 3050, the method parses the PIDs that were read at step 3018. The PIDs that are parsed include, but are not limited to, engine control module (ECM) voltage, ambient air temperature, engine oil temperature, intake air temperature, boost parameters, rail pressure desired, rail pressure actual, transmission line pressure desired, barometric pressure, variable geometry turbo position actual, variable geometry turbo position desired, exhaust gas recirculation valve position actual, exhaust gas recirculation valve position desired, mass air flow, diesel particulate filter soot load, exhaust pressure, main injector event timing, transmission shaft output speed, torque converter slip, exhaust gas temperature, and main injection quantity desired. If a value for the PID is not provided in the message, the parsing moves to the next PID (e.g., break). If the value for the PID is in the message, then the value is stored in a data structure (e.g., array, lookup table, defined variable, etc.). The method then moves to step 3052, shown in FIG. 30D.

Referring then to FIG. 30D, at step 3052 a new CAN configuration file is created, including checking CRCs against stored CRCs (e.g., those initially received from the vehicle controller). Only the modified CRCs are updated in the new configuration file.

At step 3054, a determination is made as to whether or not prior system failures have occurred.

If so, then at step 3055, the method performs a reflash recovery operation. The reflash recovery operation may include obtaining an appropriate file for the recovery, reading data from the file, downloading and/or updating the bootfile, erasing a sector of the appropriate module, writing data to the sector (e.g., for ECM and/or TCM), performing necessary iterations for other sectors, and resetting the module. The method then moves to step 3056. If not, then the method moves to step 3062.

At step 3056, a determination is made as to whether or not the reflash was successful. If not, the method moves to step 3058. If so, the method moves to step 3062.

At step 3058, the method reports an unsuccessful refresh. Step 3058 may include providing a visual alert, audio alert, or other indication of an unsuccessful function, and an indication of where the error occurred. At step 3060, the method ends the operation of the Tune Control mode.

At step 3062, the RPM of the vehicle engine is checked. If the RPM value is zero, then the method moves to step 3064. At step 3064, the method waits a predefined short time period and then returns to step 3054. Step 3064 is only repeated a finite predetermined number of times before the method times out. If the RPM value is greater than zero, then at step 3066 the method implements the power level modifications in the SOTF map.

At step 3068, DTCs are adjusted according to the newly implemented power levels and SOTF map. At step 3070, the Tune Control mode ends and the system returns to a wait state. Step 3070 may further include providing a visual alert, audio alert, or other indication of a successful completion of tuning modifications.

Referring now to FIG. 31, Output Control Mode state 2916 is further described. Output control Mode state 2916 includes volume control (e.g., increase, decrease, mute), communication output control (e.g., Wi-Fi output ceased, re-started, or paused; Bluetooth output ceased, re-started, or paused), device settings such as delay time between a beacon alert and beacon implementation, as will be further described. Alert control such as the form and type of alerts that will be displayed on the client device security prompt output, device output control (e.g., whether or not mobile devices will be allowed or restricted from using the local device as an internet access point), and combinations thereof.

At step 3102, the client device displays a menu of the output control options that are adjustable. At step 3104, the specific output is selected. At step 3106, a determination is made as to whether or not dual adjustment levels are present. If so, then at step 3108, the adjustment is made by way of the user touching the display. If not, then the method moves to step 3112. At step 3110, the output control mode ends. Step 3110 may further include a delay before the display of output control closes, enabling the user to see the selection that occurred.

At step 3112, if the output control selected from the menu at step 3104 has a multiple adjustment levels associated with it, then the client device displays the multiple adjustment levels. At step 3114, at least one of the multiple adjustment levels is selected. For example, if volume control is selected at step 3104, then a sliding GUI element may enable the user to slidingly adjust the volume level of alerts generated by the local device from multiple different volume levels. At step 3116, after making the adjustment to the desired level among the multi-level output control, the Output Control Mode ends.

Referring then to FIGS. 32, 33A-33E and 34, ELD state 2922, is further described. ELD mode includes a query for one or more of a routing code, an email address, or other additional input may be received from a safety officer or a motor authority representative. Additional input during the ELD mode may also include a report period request. For instance, the safety officer may be interested in RODS for the last 24 hours, the last week, the last six months, or another specified period of time. Receipt of the report period input may enable additional functions such as logged data retrieval from the local device, the system server, or a combination thereof. The additional input during ELD mode may also include acceptable operator annotations. For example, an operator may be able to add a comment for a specific RODS report or entry. For instance, the local device may prompt the operator, via client device, to enter waiting time information, break information, or unassigned driver information.

Referring first to FIG. 32, method 32000 shows several steps utilized by system 22000 to perform ELD mode of the local device. The system acquires logged data for, in a preferred embodiment, an administrative official such as a motor authority representative or safety officer, who uses the system with customer client device 22060 or with a motor authority client device, to display logged data, display live data, and send RODS or other vehicle/safety reports using cloud services provided by administration server 22008. For example, a motor authority official can ask an operator (i.e., customer) for vehicle data logs for a Department of Transportation (DOT) inspection. The operator uses customer client device 22060 to connect to vehicle device 22090 through system 22000. The motor authority official reviews logged vehicle data and/or live vehicle data that is provided through system 22000. System 22000 generates an on-screen inspection, based on the vehicle data and motor authority (e.g., Federal Motor Carrier Saftey Administration (FMCSA)) rules and regulations, including alerts for logs that may not be fully compliant with the rules and regulations. The motor authority official reviews the vehicle data and otherwise performs the on-screen inspection. The official then may instruct system 22000 to transfer the vehicle data to the motor authority client device or third party server 22020. An example is a motor authority server.

At step 32020, vehicle data is generated by vehicle device 22090. The vehicle data includes data, information, and code from one or more sensors, systems, and devices that are connected to vehicle device 22090.

At step 32022, vehicle device 22090 sends vehicle data, to local device 22074.

At step 32024, local device 22074 generates logged vehicle data. The logged vehicle data is a set of the data that includes one or more of off duty time, sleeper berth time, driving time, on-duty not driving time, annotations, driver's location description and modifications, comments, commercial motor vehicle power unit number, mileage records, trailer number(s), shipping document number(s), driver hours of service (HOS) records, RODS, and combinations thereof. Step 32024 further includes encapsulating the logged vehicle data and forming packets for transmission. Step 32024 may further include filtering each section of a message frame, such as with an XOR operation, a parity check, or a delta operation, to determine if each of the required sections includes data. If the filter indicates that each of the required sections includes data, then the logged data may represent a certified log. The required sections include, but are not limited to, the calendar day for which vehicle data logs were created, a driver ID for the operator during creation of the ROD.

Step 32024 may further include sorting the data for the vehicle logs. The data may be sorted according to day, time frame (i.e., period), and transaction for the logged vehicle data. The timeframe identifies the length of a window of time for vehicle data, such as the previous 24 hours of vehicle data. The transaction identifies how the encapsulated, packetized, or logged data should be handled (e.g., displayed according to a display protocol, transmitted via email, transmitted via local connection such as Bluetooth, etc.) by local device 22074 before being discarded and includes, in a preferred embodiment, options for data compression, data transmission, and file transfer comments.

At step 32026, a link is established between local device 22074 and customer client device 22060. For example, local device 22074 may be established as a Wi-Fi access point, through which customer client device 22060 may access the internet as well as communicate with administrative server 22008. By way of another example, the link may be a short-range, Bluetooth connection between local device 22074 and customer client device 22060.

At optional step 32028, a link may be established between customer client device 22060 and customer client device 22060. The optional link may allow for local, short-range transfers, such as Bluetooth or peer-to-peer (P2P) data transfers.

At step 32030, a logged vehicle data request is generated by customer client device 22060. Step 32030 may further include generating a period request or including additional information with the request such as the time frame for which the logged data is requested. Step 32030 may further include prompting the operator for a routing code (e.g., provided by a safety officer or motor authority representative), a destination IP address, and/or other transactional information.

At step 32032, customer client device 22060 sends the logged vehicle data request, which is received by the local device 22074. At optional step 32034, a notification is sent from customer client device 22060 to administrative server 22008 of the logged data request.

At optional step 32036, customer client device 22060 generates authorization for local device 22074 to transfer logged data to a linked motor authority client device. At step 32038, the authorization is sent to local device 22074.

At optional step 32040, the logged vehicle data request may be generated by technician client device 22046. At step 32041 the technician client device may also include prompting the administrative server for a routing code or other transactional information.

At optional step 32042, technician client device 22046 sends the logged vehicle data request, which is received by local device 22074. At optional step 32044, a notification is sent to administrative server 22008 of the logged data request.

At step 32046, administration server 22008 identifies the devices associated with the request. For example, administrator server 22008 may identify customer client device 22060, local device 22074, and/or technician client device 22046 associated with the request.

At step 32048, the logged vehicle data response is generated. At step 32050, the logged vehicle data is filtered by local device 22074. The logged vehicle data is filtered based upon the contents of the logged vehicle data request that was initiated with either customer client device 22060 or technician client device 22046. For example, if the timeframe in the logged data request is the last 24 hours, then the local device filters the logged vehicle data such that only the last 24 hours of logged data is prepared to be sent in the response.

At step 32051, the local device provides a certified log of vehicle data, as will be further described.

At step 32052, local device 22074 sends the logged vehicle data response, which is received by customer client device 22060. At step 32054, customer client device 22060 stores and displays the logged vehicle data from the logged vehicle data response. At optional step 32056, customer client device 22060 sends the logged vehicle data response to third party server 22020.

At optional step 32058, local device 22074 sends the logged vehicle data response to technician client device 22046. At optional step 32060, technician client device 22046 displays the logged vehicle data response for the on-screen inspection.

Referring to FIGS. 33A and 33B, after selection of the appropriate application from customer client device 33000, a user may select an ELD mode or function from a list of modes/functions of local device 33002. Upon selection of an ELD mode, user interface 33005 displays options for accessing logged vehicle data that is received from local device 33002. The data displayed with user interface 33005 can be directly from local device 33002, can be from customer client device 33000 and displayed on technician client device 33006, or it may be from an administration server that received the data after the data was transmitted from local device 33002. User interface 33005 includes several user interface elements.

Menu button 33007 (further described below) is a menu button that, once selected, brings up a main menu. The main menu allows the user to select different functions within the application.

User interface button 33008 (e.g., element/button of capacitive-touch display) has been selected to send logs to technician client device 33006 or a mobile authority server (e.g., FMCSA). GUI 33010 is configured to receive transaction information, such as a routing code, with user interface element 33012. In some embodiments, user interface button 33008 is a flat navigation element, meaning that upon selection, relatively few additional GUIs will be necessary to obtain the desired function (e.g., one GUI 33010 used to send logs with button 33013).

Referring to FIGS. 33A and 33C, user interface button 33014 has been selected to conduct a second function of the application (e.g., an on-screen inspection). GUI 33016 is configured with multiple menu buttons 33018. In some embodiments, multiple menu buttons 33018 are flat navigational elements to access a two- or three-level hierarchy of data related to the selected function, such as the on-screen inspection. For example, the selection of a first menu button 33018 may result in a display of dates associated with certified logs. The user interface element Un-ID'd LOGS is shown at 33035. User interface element 33035 includes certified check boxes such as 33034 and 33036. If the boxes are checked, the logs are certified. If they are not checked, the logs are not certified.

Button 33020 is a user interface element that, upon being selected, shows vehicle data associated with a specific, certified log. For example, each of the dates displayed in GUI 33016, after selection of button 33018, may be an interactive user interface element providing access to respective, associated certified logs and related data. The dates of GUI 33016 may be displayed together as a scrollable GUI.

Referring to FIGS. 33C and 33D, upon selection of button 33020, GUI 33022 is displayed. GUI 33022 may include additional menu buttons. For example, a first menu button 33024 may be selected to display broad-level data and interpretations pertaining to a specific, certified log. The broad-level data and interpretations may include Records of Duty Status (RODS), graphical representations, playback charts (e.g., for live data creating current RODS or a current ELD log), changes in duty status, hours, associated mileage, name of the city/town, State abbreviations, driver ID, and combinations thereof. For example, a graph view 33025 may display RODS information and hours related thereto. A second menu button 33026 may be selected to obtain additional information for the specific, certified log. For example, the certified log for Wednesday, January 31, may include additional related information such as fuel receipts, toll receipts and records, trip reports, bills of lading, verification documents, and combinations thereof.

Referring to FIG. 33E, chart view 33030 of GUI 33022 may be used in place of, or together with, graph view 33025. For example, a toggle button (not shown) may be used to switch between graph view 33025 and chart view 33030. Each of graph view 33025 and chart view 33030 may be scrollable displays, which may be scrolled to obtain additional information about the displays or information presented therein. In some embodiments, GUI 33022 may include an input prompt for annotations, which are received according to a specified format (e.g., “Day, Comment”).

A zoom feature may be associated with the graphical representation and other features of the GUIs discussed in FIGS. 33A-33E. In such cases, appropriate data interpolation may be used.

Referring to FIG. 34, a method of generation of a certified log as shown in step 32051, will be further described. The generation of the certified log may be processed based on format, content, or associated metadata. At step 3402, local device 22074 makes a query regarding date and time. The date and time is provided by a local clock within local device 22074, or a clock within vehicle device 22090, and stored in a first array. At step 3404, local device 22074 makes a query regarding a driver ID. If the driver ID is entered through a GUI of local device 22074, then the data is stored in a second array. If the driver ID is not entered, then the method proceeds to step 3406 and queries the ECU for any data required for at least one ROD. The data resulting from step 3406 includes, but is not limited to, RPMs greater than zero, period of time RPMs are greater than zero, RPMs greater than a specified idle value, period of time RPMs are greater than the specified idle value, gear value, and period of time associated with gear value.

At step 3408, local device filters and sorts the data according to date, time, and preprogrammed classifications. The preprogrammed classifications include, but are not limited to, ‘vehicle driving’, ‘vehicle idling’, and ‘vehicle off’. Step 3408 further includes performing a data calculation or data check, such as a simple parity check or XOR operation, to determine if each required field has content within it.

At step 3410, the results of step 3408 are checked to determine if each required field is populated with data. At step 3412, if each required field is populated with data, then a “certified” log is generated. An indication is provided on user interface GUI 33016 that a log is “certified”. At step 3415, the method then ends.

At step 3410, if each required field is not populated with data (e.g., driver ID is missing), then a log may be created by local device, but it is not “certified”. At step 3414, an indication is provided on user interface GUI that a log is not certified. At the same time, if one or more entries are significantly different from expected value(s), such as by two or more parameters, e.g., driver ID is missing and the calendar day has been altered, then an alert is generated. The alert is communicated to the administrative server. At step 3415, the method then ends.

Referring again to FIGS. 5A-16A and the accompanying text, Live Data mode 2928 is described. For example, if Live Data Mode 2928 is selected, then the local device is configured to provide live data from any of the many vehicle computers, sensors, and detectors to a display of the client device.

Referring then to FIG. 35, third party proxy mode 2934 will be further described.

In third party proxy device mode, the third party proxy device can, upon executing method 3500, honk the horn, turn on the lights, set interior HVAC controls or execute other functions which alter the performance or appearance of the vehicle to which the vehicle controller is connected.

Method 3500 includes system server 102 in communication with third party proxy device 3501. In a preferred embodiment, third party proxy device 3501 includes smart phone running an appropriate application to generate the functions shown.

At step 3510, third party proxy device 3501 generates a proxy request. A proxy request includes a set of vehicle functions which third party proxy device 3501 wishes to execute on vehicle device 114. At step 3512, the proxy request is sent to system server 102. At step 3514, system server 102 logs the proxy request and identifies the appropriate vehicle device 114 and associated local device 112 and associated client device 110. At step 3516, system server 102 sends the proxy request to client device 110. At step 3518, client device 110 authorizes the proxy request. At step 3520, client device 110 sends a proxy authorization to system server 102. At step 3522, system server 102 logs the proxy authorization. At step 3524, system server 102 sends the proxy authorization to third party proxy device 3501. At step 3526, third party proxy device 3501 generates a set of proxy vehicle instructions. At step 3528, third party proxy device 3501 sends the proxy vehicle instructions to client device 110. At step 3530, client device 110 approves the proxy vehicle instructions. At step 3532, client device 110 sends the proxy vehicle instructions to local device 112. At step 3534, local device 112 formats the proxy instructions for the vehicle device. At step 3536, local device 112 sends the formatted proxy vehicle instructions to vehicle device 114. At step 3538, vehicle device 114 executes the formatted proxy vehicle instructions.

Referring to FIG. 36, implementation of a security function within local device 112 will be further described.

Method 3600 includes local device 112 in communication with power controller 2818. In a preferred embodiment, vehicle device 114 includes an over-the-air configurable power controller operating independently from the main processor of local device 112. An example is shown in FIG. 28.

At step 3610, client device 110 starts the mobile device application. At step 3612, local device 112 powers on and boots up. At step 3614, vehicle device 114 boots up. At step 3616, vehicle device 114 retrieves a version number from memory. At step 3618, the vehicle device sends the version number to local device 112. At step 3619 local device 112 stores the version number. At step 3620, the application on client device 110 generates a request for the version number. At step 3622, client device 110 sends the request for the version number to local device 112. At step 3624, local device 112 retrieves the version number from memory. At step 3626, local device 112 sends the version number to client device 110. At step 3628, client device 110 retrieves authentication data. The authentication retrieved includes the power controller version number, a code number, and a serial number of the local device. In a preferred embodiment, the code number is produced by an algorithm that provides independently repeatable results based on a seed number. In a preferred embodiment, the algorithm may be a cryptographic cypher based on chaos theory, a serial 256-bit function, or another non-linear function. At step 3630, client device 110 sends the authentication data to system server 102. At step 3632, system server 102 checks the authentication data against stored authentication data. In one embodiment, the authentication data is one or more of version number, serial number and code number. At step 3634, system server 102 generates an authentication response including an update. The authentication response includes an authorization response or a non-authorization response, and the update includes an update for one or more of the mobile application on client device 110, local device 112, and vehicle device 114. At step 3636, system server 102 sends the update to client device 110. At step 3638, client device 110 receives the update, and optionally installs the update for the mobile application. At step 3640, client device 110 sends the update to local device 112. At step 3642, local device 112 receives the update and optionally installs the update. At optional step 3644, local device 112 reboots. At step 3646, local device 112 sends the update to vehicle device 114. At step 3648, vehicle device 114 receives and installs the update. If the update includes an authorized authentication response, then vehicle device 114 receives and installs the update at step 3648. At optional step 3650, power controller 2818 reboots. However, if the update includes a non-authorized authentication response, vehicle device 114 receives and installs the update, but the update causes vehicle device 114 to generate one or more power control signals. The one or more power control signals cause at least one of vehicle device 114 and local device 112 to shut down or enter an insecure mode. In a preferred embodiment, the power control signals implement a power throttling or security function including, but not limited to, reducing power to one or more integrated circuits of local device 112, performing a hardware interrupt, a circuitry reset, accessing one or more fuses of an electrical fuse array, receiving a cold reset negative logic input, or a combination thereof.

Referring to FIG. 37, setup of J2534 compliant local device 112 will be described as process 3700.

At step 3702, user opens application 111 on client device 110. At step 3704 a user account is created by entering personal information, such as name, email address and telephone number, and vehicle information, such as VIN, year, make, and model. At step 3708, the calibration writer server creates an account based on information from the system server. The calibration writer server includes account information such as name, address, email address, and submit computer Cal/Pid. At step 3710, calibration writer server determines a set of operating system parameters which includes programming information, such as communication protocol and look up tables for the onboard controller. At step 3712, the parameters are submitted to system server 102. At step 3714, system server 102 stores the parameters and the account implementation. At step 3716, the database is updated by the system server with the account information and system parameters. At step 3718, the system server uploads the system parameters to client device 110 via a wireless network.

At step 3720, client device 110 stores the system parameters. At step 3722, client device 110 establishes a wireless connection with local device 112 through Bluetooth or Wi-Fi. At step 3724, user initiates device setup. At step 3726, client device 110 uploads system parameters to local device 112. At step 3728, local device 112 stores system parameters. In step 3730, local device 112 establishes a communication connection with vehicle device 114 through an OBD II port utilizing the communication protocol determined from the system parameters. In a preferred embodiment OBD II port is a J1962 connector. At step 3732, vehicle device 114 acknowledges the connection. At step 3734, a message is generated containing vehicle device 114 details, such as software version numbers, automotive controller and engine control unit models and serial numbers.

At step 3736, acknowledgement and details are sent to local device 112. At step 3738, the details are stored in local device 112. At step 3740, details are transmitted to client device 110. At step 3741, client device stores details. In step 3742, the details are relayed to system server 102. At step 3744, the system server stores vehicle device 114 details. At step 3746, system server 102 updates database 106.

In step 3748, application 111 displays potential settings and system operation parameters for vehicle device 114 on client device 110. At step 3750, user selects desired options which are received by the client device. In step 3752, the selected parameters are uploaded to local device 112. At step 3754, the selected parameters are stored on local device 112. In step 3756, local device 112 uploads the parameters to vehicle device 114. In step 3758, vehicle device 114 logs the parameters. At step 3760, the parameters are implemented. At step 3762, the implementation of the parameters is acknowledged. At step 3764, acknowledgement is sent to local device 112. In step 3766, the acknowledgement is reported to client device 110. At step 3768, client device 110 displays the status of vehicle device according to the set parameters.

Referring to FIG. 38, administrative process 3800 for updating the J2534 application files is described.

At step 3802, administrator user opens cloud-based web application on administrator device 22032. In step 3804, logon credentials are received. At step 3806, administrator logon request is submitted to administrator server 22008. At step 3808, administrator server 22008 logs the request. At step 3810, the server verifies the administrator logon credentials. If the logon credentials are incorrect, then at step 3812, a denial is generated. At step 3814, the denial is then transmitted to administrator device 22032. If the logon credentials are correct, then at step 3816, administrator server 22008 approves the logon request. At step 3818, administrator server transmits the administrator web application to administrator device 22032.

At step 3819, administrator web application is displayed. At step 3820, the J2534 Application tab is chosen. At step 3822, a selection to add a new version of J2534 Application 126 is received.

In step 3840, system server 102 stores the new version.

Referring to FIG. 39, setup of a receiving device for the remote analysis and reprogramming of vehicle device 114 will be described as process 3900. While in this figure the receiving device is shown as technician device 124, in alternate embodiments, the receiving device can be either technician device 124, or third-party device 130.

At step 3902, a request is made for access to OEM API 128 for a vehicle manufacturer. At step 3904, an account is created with the manufacturer or dealer. At step 3906, the request for OEM API 128 is submitted to the appropriate dealer or vehicle manufacturer. At step 3908, the request is logged by dealer device 116. In step 3910, access is either granted or denied. If access is granted, then in step 3912, dealer device 116 provides technician device 124 with the application file for OEM API 128. If denied, the process terminates. At step 3914 OEM API is updated. In step 3916, the updates are transmitted to technician device 124. At step 3918, technician device 124 downloads OEM API 128 and any updates. In a preferred embodiment, OEM API 128 is accompanied with an OEM application program and both are downloaded and installed on the technician device.

At step 3920, technician device 124 opens cloud-based web application. At step 3922, logon credentials are entered. In step 3924, the login request is transmitted to system server 102. At step 3926, system server 102 verifies the credentials entered. If the credentials are incorrect, then in step 3928, the request is denied by system server 102. If the request is denied, then in step 3930, a denial message is transmitted to technician device 124. If the credentials entered are correct, then in step 3932, the logon request is approved. In step 3934, a cloud-based web application program is generated. At step 3935, the web application program is transmitted to technician device 124. At step 3936, the web application program is displayed. In step 3937, the J2534 Application tab is selected. An example of the J2534 Application tab of the web application screen is shown in FIG. 41B. In step 3938, a version of J2534 application 126 is selected. In step 3940, a request to download the selected version of J2534 application 126 is submitted. At step 3942, the download request is transmitted to system server 102. In step 3944, system server 102 logs the request. At step 3946, the selected version of J2534 application 126 program file is transmitted to technician device 124. In step 3948, technician device downloads J2534 application 126. The J2534 DLL file may be required for communication between the manufacturer OEM application, client device, and local device.

Referring to FIG. 40, the system for remote J2534 reprogramming of vehicle device 114 is described.

At step 4002, the cloud-based web application is opened on technician device 124. At step 4004, logon credentials are entered. In step 4006, the login request is transmitted to system server 102. At step 4008, system server 102 verifies the credentials entered. If the credentials are incorrect, then in step 4010, the request is denied by system server 102. If the request is denied, then in step 4012, a denial message is transmitted to technician device 124. If the credentials entered are correct, then in step 4014, the cloud-based web application is generated. At step 4016, the web application program is transmitted to technician device 124.

In step 4018, technician device 124 displays web application. In step 4020, a client is selected and client profile details, such as email, and details of local device 112 and vehicle device 114 are shown. In step 4022, a specific vehicle from a list of multiple vehicles is selected. In an alternate embodiment, an ECU profile configuration may be selected from a list of optional configurations and downloaded to the technician device as follows. In step 4024, an ECU profile configuration for a vehicle is selected from a list of potential ECU profiles. An example of a technician view of available ECU profile configurations is shown in FIG. 41C. At step 4026, the selected ECU profile configuration is requested.

At step 4028, the ECU profile configuration request is transmitted to system server 102. In step 4030, system server 102 will log the request. In step 4032, system server 102 will forward the request to calibration writer server 118. At step 4034, the request is logged. In step 4036, calibration writer server 118 will determine parameters for the requested profile based on selected client, selected vehicle, and selected ECU profile. For instance, when the ECU has a custom configuration it may require different parameters for an ECU re-flash then when the ECU has a standard OEM profile. At step 4038, the selected profile is transmitted to the system server. In step 4040, system server 102 logs the profile. In step 4042, the profile is forwarded to technician device 124.
