EMS3125 Module 1 for owners of the EMS3120 module is intended for Renault/VAZ Logan 2, Sandero 2, Kaptur and Lada XRAY vehicles with H4M or F4R engines, manual or automatic transmissions and Continental EMS3125 ECUs.
The module provides basic calibration maps, including an extended DTC mask, detailed identification data, reprogramming log information, downstream oxygen sensor and catalyst monitoring settings, lambda control thresholds, starting calibrations, torque limits and requests, rev limiter, VVTC, fans, injectors and evaporative emissions control.
After editing, the main and extended calibration checksums are recalculated, allowing the firmware to be written with a compatible programming tool. See the developer forum for the supported firmware list.
