Module ChipTuningPRO VAZ M74.5 allows for professional chip tuning of VAZ cars equipped with the new ECU M74.5.
ESUD is installed on cars with the 21127 engine, equipped with a variable geometry intake system and an absolute pressure sensor instead of the usual DMRV. Despite the name "M74", the software of this system is a further improvement of the ESUD M75, not M74, as one might assume. Some significant changes have been made to the algorithmic model compared to M75: the control algorithm for the intake geometry switching valve, a new algorithm for calculating cyclic filling based on absolute pressure, a new algorithm for calculating CN in "throttle" mode, individual CN corrections per cylinder, etc. All these innovations are available for editing. There are over 700 open calibrations in the maps, providing virtually unlimited possibilities for chip tuning.
Module features:
- Ability to open firmware in SMS-Soft Container File format (new format for ChipTuningPRO and CombiLoader)
- Ability to open firmware in BIN format (regular binary file)
- Automatic checksum calculation when saving firmware
- To provide additional protection against accidental modifications of data that may affect driving safety, firmware is saved by default in SMS-Soft Container File format, compatible with CombiLoader
ECU programming is done using the loader CombiLoader.
To use the module, you need to purchase a ChipTuningPro USB protection key. The key can be purchased in our store. You can purchase an unlimited number of modules for one key.
Updates of descriptions for new software versions within the module are free.
Module activation is done within 1 hour on business days (usually 10-15 minutes). Activation may be delayed on weekends and holidays (up to 2 hours).
To activate the module, you need to send a request for module activation, full name, and email.
An activated module or license cannot be returned.
If you have entered the wrong key or device number, the return is not valid. It is not possible to modify the license for another device.
After status update to "Waiting for activation", the data has already been sent to the developer for activation. The order cannot be canceled or corrected starting from this status update.
Pay attention to all information specified in the description of modules and scripts taken from the manufacturer. We are not responsible if the information is not correct or there are some differences from the reality. In the disputed situation, it is necessary to look for a solution to the issue to the manufacturer.
Our store is not responsible for the functionality of the software module. We cannot guarantee the declared functions since we are not the developer.
