MMR PERFORMANCE

POWER CONTROL MODULE
BMW G8X M-CARS | M2 | M3 | M4

MMR50-1601, 1602

Why fit?

Introducing MMR PCM; Power Control Module. A plug-and-play increase in power for G-Series M-Cars. Removable and undetectable. 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.

Benefits of fitting?

Unlock unparalleled power, effortlessly.

Maybe your G-Series M-Car can't yet be tuned via conventional methods or you're concerned about the warranty. Well, whatever the reason, not everyone is ready to tune their car through traditional methods; the MMR PCM could be your perfect tuning solution!

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.

Install at home, yourself.

PCM has a simple installation, providing you have a basic level of mechanical knowledge. The PCM unit sits in the engine bay using the provided carbon fibre mount and hardware, while the wiring loom is plugged into existing sensors in the engine. Or for full peace of mind, all of our approved PCM dealers around the world can also install this for you, subject to labour charges.

What PCM does.

PCM works by using our in-house developed calibration running on our standalone PCB, which communicates in parallel with the factory ECU. This communication route allows the PCM to safely optimise a variety of electronic sensor signals in real-time, interfacing between the engine controls and its sensors.

With multiple channels such as charge air pressure, ignition, and fuelling controlled by the PCM computer, the result is increased power and torque across the whole powerband of the engine.

We have carried tens of thousands of development miles of rigorous testing on our in-house dyno, on road and on track with numerous calibrations, across multiple cars and different hardware installations, allowing us to find the sweet spot for engine performance, drivability, and safety.

Everything you need.

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.

Cooled by fins.

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.

PCM vs ECU Calibration.

We're completely honest about this, the PCM calibration is not as sophisticated as a full ECU calibration. To keep the car smooth, safe and reliable, PCM's power levels have to be kept lower than traditional ECU calibrations. But of course, you'll love the power boost you get from PCM, combined with the drivability and efficiency gains.
