Module ChipTuningPRO VAZ M86/M74M + MULTIMODE allows for professional chip tuning of Lada Largus, Granta, Vesta, and X-Ray cars equipped with ECU M86 and M74M with software produced by VAZ.
Over 600 calibrations of the M86 control system are available for editing: configuration, DTC mask, starting modes, lambda regulation, ignition misfire diagnostics, idle control, fuel delivery with dynamic corrections, torque model, EGAS system calibrations, speed limitation and cruise control calibrations, and more.
ECU M86 is used in Lada Largus, Lada Vesta, and X-Ray cars. The M86 project is a further development of the M74/M75 engine management systems.
ECU M74M is serially installed in VAZ cars since mid-2019.
Module features:
- Over 600 calibrations available for editing
- Automatic checksum calculation when saving firmware
- Working with BIN format files
- Creating multi-mode firmware with the ability to switch between 3 complete sets of calibrations, disabling injectors and fuel pump with programmable delay in any of the modes (detailed description can be found in the ChipTuningPRO help)
- Ability to fix firmware checksum during editing: desired checksum displayed on dealer diagnostics remains unchanged when editing calibrations
- Ability to add vehicle speed limitation function not present in stock software
- Patch for lean mixture enrichment above stoichiometry, which is not possible in stock software
- Patch for enabling cruise control and idle speed control in configurations without ABS/AMT
- Patch for adding tilt and offset calibration to the software code (these calibrations are not present in stock software)
ECU programming is performed using the CombiLoader tool.
