Module ChipTuningPRO VAZ M74 allows for professional chip tuning of VAZ cars with electronic throttle (EGAS) equipped with the latest M74 ECU. It also supports editing of M74K firmware for VAZ "Classic" cars without electronic throttle.
More than 380 calibrations of the M74 control system are available for editing: starting modes, ignition timing, fuel delivery with dynamic corrections, torque model, EGAS system calibrations, error mask, etc. The checksum is calculated and adjusted automatically. The module calculates the checksum when saving the firmware.
Module features:
- Possibility to edit the logger (additional license required)
- Possibility to create multi-mode software (additional license required)
- Possibility to fix the firmware checksum during editing: the desired checksum displayed on the dealer's diagnostics remains unchanged when editing calibrations
- Possibility to add a vehicle speed limitation function not present in the stock software
- Patch for lean mixture above stoichiometry, which is not possible in stock software
- Patch for adding tilt and offset calibration to the program code (these calibrations are not present in stock software)
ECU programming is performed using the CombiLoader loader.
