MMR Power Control Module – BMW M3

A plug-and-play increase in power for G-Series M-Cars. Removable and undetectable.

With over 12 months of development under our belt, we’re uber excited to release our tuning solution for all G-Series M-Cars. Say hello to the MMR PCM! With a limited market for tuning potential, our PCM is a plug-and-play solution which is easily installed and easily removed at any time without a trace. Not to mention a substantial increase in power and torque throughout the entire rev range. More on that below…

We’ve carried out tens of thousands of development miles of rigorous testing on our in-house dyno, on the road and on the track. With numerous calibrations across multiple cars and different hardware installations, allowing us to find the sweet spot for engine performance, drivability and safety. We offer two types of PCM: one for the higher-output M-Cars such as the G80 M3 and G82 M4, and the other is for the G87 M2. Our PCM works on all X-Drive and RWD models including Competition and non-Competition models.

PCM works on a standalone PCB, which communicates with the factory ECU. Developed by MMR’s own in-house calibration experts over the past 12 months, it allows the vehicle to safely increase power and torque levels throughout the entire rev range.

Easily installed, and easily removed at any time without a trace. With 12 months of detailed development, our PCM is more than a ‘tuning box’. The kit is complete, including a perfect fit wiring loom made especially for the selected vehicle.

The unit itself is housed in a stunning billet aluminium case, finned to ensure adequate cooling plus a beautiful carbon fibre mounting bracket to affix it securely in your engine bay.
