## Description

The MMR aftermarket ECU for the BMW M3 CS and M4 CS F8x allows power to be increased to approximately 520 ch while delivering over 70 Nm of additional torque. Developed specifically for the highest-performance versions of the S55 engine, it significantly improves acceleration, responsiveness, and torque delivery.

Thanks to its electronics developed in-house by MMX Performance, the PCM acts as a true auxiliary control unit capable of continuously optimizing engine parameters without altering the original engine management system.

Supplied with a dedicated Plug & Play wiring harness, a carbon fiber bracket, and a high-quality aluminum housing, this system offers a simple, reliable, and fully reversible installation.

An ideal solution for fully unlocking the potential of the CS models.
