MMX BMW G87 M2 S58 Engine Power Control Module

Unlock the true potential of your BMW G87 M2 (3.0 S58) with the MMX Power Control Module (PCM) – a plug-and-play upgrade delivering up to +100 HP and +100 NM of torque across the rev range. Designed as a safe and warranty-friendly solution, the PCM is removable, undetectable, and requires no ECU removal or permanent modifications.

Unlike basic tuning boxes, the MMX PCM acts as a secondary ECU, developed over 12 months of rigorous testing on dyno, road, and track. Running in parallel with the factory ECU, it optimises multiple channels in real time – including charge air pressure, fuelling, and ignition – for seamless integration and maximum performance without compromising drivability or safety.

Housed in a billet aluminium case, anodised in MMX’s signature gloss black, and mounted securely via a carbon fibre bracket, the PCM combines precision engineering with a premium finish. Each kit includes a vehicle-specific loom for a perfect fit and simple installation.
