MMX Performance F8X S55 Power Control Module

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 optimize electronic sensor signals in real time, interfacing between the engine controls and its sensors.

With multiple channels 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.

With 12 months of detailed development, our PCM is so much more than a 'tuning box', and is in fact closer to a secondary ECU. 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 aluminum case, finned to ensure adequate cooling plus a beautiful carbon fiber mounting bracket to affix it securely in your engine bay.
