Power Control Module for S58 Engines

The MMX Performance Power Control Module (PCM) provides a substantial power increase for S58-powered BMW M-cars like the G87 M2, G80 M3, and G82/G83 M4. This module utilizes MMX's standalone tuning architecture, communicating in parallel with the factory ECU to optimize engine output across the entire powerband by interfacing with charge air pressure, ignition, and fueling channels. It is designed as a plug-and-play solution that leaves no electronic trace and can be removed at any time, making it an appealing option when warranty considerations are a factor. Constructed with a finned billet aluminum case finished in MMX gloss black anodization, this PCM includes a carbon fiber mounting bracket for a clean installation. The unit is engineered and hand-assembled in the UK, with extensive development miles logged on dyno, road, and track. Installation requires no tools or permanent modifications, as it connects directly into the engine bay sensor harness. The PCM offers significant power and torque gains. For the G87 M2 (2023+), expect an increase of +100 HP / +100 Nm, bringing the output from 450 HP stock to 550 HP and 550 Nm to 650 Nm. The G87 M2 LCI (2025+) can see gains from 480 HP stock to 580 HP and 600 Nm to 685 Nm. The G80 M3 / G82 M4 High Output models gain +110 HP / +140 Nm. Specific variants like the G87 M2 CS and G8X M3 M4 CS/CSL/Touring have their own specified gains. Important notes for this product include a 1-year manufacturer warranty and that it is designed and tested in the United Kingdom. Crucially, this module is not for sale or use in California. Additionally, CS/CSL models may require specific module coding, and this particular module may not be compatible with those variants.
