The MMX Power Control Module is a plug-and-play power upgrade for the BMW G8x M3 and M4, built around the 3.0-litre S58 engine. It raises output to approximately 480HP while remaining fully removable and undetectable, making it a practical option for owners who want more performance without permanent ECU modification.
Unlike a conventional ECU remap, the module installs and removes in minutes, leaving no trace on the factory ECU. This makes it well suited to owners who want to preserve their standard warranty or who are not able to use traditional tuning methods.
