Description
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!
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.

Note:
It's very clear - any tuning modification on your vehicle can invalidate your manufacturer's engine & powertrain warranty. So if your dealer sees the PCM fitted, then they'd be entitled to reject a warranty claim on the engine or drivetrain.
Of course, PCM is fully removable. With it removed, the car is returned to true stock, but whilst PCM leaves minimal trace to the ECU, it's important to understand that there is no guarantee that this product is warranty safe and is installed at the customers’ own risk.
