MMX BMW S55 Power Control Module For BMW F80 M3, F82/F83 M4 & F87 M2 Competition

The MMX Power Control Module (PCM) is the ultimate plug-and-play tuning solution for S55-powered BMW F-Series M-Cars. Designed for the F80 M3, F82/F83 M4, and F87 M2 Competition/CS, the PCM delivers a significant increase in power and torque while remaining fully removable and undetectable. It’s the smart choice for owners who want more performance without a full ECU remap.

Developed over 12 months of intensive testing, the PCM runs a bespoke calibration on a standalone PCB that works in parallel with the factory ECU. By optimising multiple channels such as boost pressure, ignition, and fuelling, it unlocks smooth, safe, and reliable gains across the entire rev range. The billet aluminium case, anodised in MMX gloss black with cooling fins, is paired with a carbon fibre mounting bracket and vehicle-specific wiring loom for a factory-quality fit.

Unlike a full ECU remap, PCM power levels are kept slightly lower to prioritise safety, drivability, and long-term reliability. The result is a noticeable power boost, sharper throttle response, and enhanced drivability — all while retaining factory refinement.
