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

Maybe your F-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!

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 fueling 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.

Easy replacement and noticeably fresher air
Size: 1-Pack
Installation was quick and simple, and it fit perfectly in my vehicle. I noticed an immediate improvement in the air quality inside the car. The activated carbon helps reduce odors and keeps the air feeling cleaner and fresher, especially during everyday driving. The filter feels well-made and durable, and it does a great job trapping dust and debris. It’s a simple upgrade that makes the driving experience much more comfortable. Overall, this is a great quality cabin air filter that delivers reliable performance and excellent value. Definitely recommend!
