Setup

Factory integration​

For a factory integration the configuration comes down to a few steps:

  • Make sure the car is coded to work with an automatic transmission.

  • Open EGS Bridge Manager and go to Configuration → Integration

    • From the Vehicle preset list, select the correct car
    • From the EGS preset list, select the matching transmission generation
    • From the Display gear limit list, select a value that matches what the stock instrument cluster supports

  • Go to Configuration → Speed

    • From the Diff ratio list, select the differential ratio closest to the actual one
    • In the Wheel circumference (mm) field, enter the wheel circumference; you can calculate it with the Calculate... button

  • Go to Configuration → Misc

    • In the Maximum allowed RPM field, set the RPM limit slightly below the cutoff
    • In the Target idle RPM field, enter the typical idle RPM of a warmed-up engine

  • Go to Transmission and make sure all values were read correctly

  • Go to Transmission → Flasher, click Full flash, then select the correct transmission type and the fuel type used in the target car. Depending on the transmission generation, the procedure takes from a few to several minutes. During it, the appropriate software is flashed to the transmission and the immobilizer is disabled. When it finishes, go back to Transmission and click Read info. The IMMO field should show Unlocked

  • Go to Data trouble codes and clear the faults

  • Go to Controller → Internal logger and set Logging enabled to True

  • Start the engine. Check that the live values shown at the bottom of the program are correct, in particular Engine RPM, TPS and Brake pedal

  • Take a test drive and calibrate the speed:

    • Go to Configuration → Speed and click the Calibrate... button. Keep a constant speed during calibration.
    • Go to Transmission and click Reset next to Diff ratio. Keep driving, clicking Read from time to time. While the differential ratio is being learned, the status shows progress in yellow, and once finished Calibrated. Make sure the Calibrated ratio and Learned ratio values are identical and match the differential ratio you selected earlier.

  • After the test drive, go to Controller → Internal logger, click Refresh and download the drive log. Then go to Logger and click Open log file. Review the log and make sure the engine ECU reduces torque correctly during shifts: the Torque value should be noticeably lower when the torque-reduction request, i.e. Torque reduction %, is greater than 0. See: example.

Standalone ECU integration​

A standalone ECU integration additionally requires selecting the appropriate ECU from the ECU preset list in Configuration → Integration.

This option is intended for advanced users. It requires configuring the engine ECU yourself and knowing its capabilities. The controller provides a fully configurable CAN stream, while delivering the required signals and handling the requests the controller sends are up to the user.

For correct operation:

  • the engine ECU delivers all the required signals to the controller (see Supported integrations),
  • the engine ECU responds correctly to the torque-reduction requests the controller sends during a shift.

Keep in mind that standalone ECUs usually do not report the lowered torque value back during a shift. Unlike factory ECUs, the log may therefore not show a drop in Torque. That does not change the fact that actual torque reduction during the shift is required, and implementing it correctly on the engine ECU side is the user's responsibility.
