Description
Unlock the full potential of your BMW G8X M-Car with the MMX Performance Power Control Module (PCM) — a plug-and-play solution that optimizes engine parameters in real-time for maximum performance and drivability, all without interfering with your factory ECU.
Key Features:
- Compatible with BMW G87 M2, G80 M3, and G82/G83 M4
- Parallel ECU signal processing for real-time performance optimization
- Controls boost pressure, ignition timing, and fueling
- Billet aluminum housing with finned design for cooling
- Carbon fiber mounting bracket for secure, stylish engine bay integration
- Completely removable and undetectable when uninstalled
- Anodized gloss black finish with signature MMR styling
- Engineered and calibrated in-house in the UK
- Vehicle-specific wiring harness for plug-and-play install
How It Works:
Unlike traditional ECU remapping, the MMX PCM operates in parallel with your factory ECU using a standalone PCB and proprietary calibration, built from the ground up by MMX engineers. It intercepts and enhances key sensor signals — including charge air pressure, ignition timing, and fuel delivery — to intelligently increase performance while maintaining factory safety protocols.
Backed by extensive dyno, road, and track testing, the MMX PCM is the result of tens of thousands of development miles across multiple hardware configurations to ensure perfect drivability and safety.
Installation & Use:
Installation is quick and straightforward using the included vehicle-specific wiring harness and carbon fiber mounting bracket. The module is completely reversible and leaves no trace when removed, making it ideal for leased or warranty-sensitive vehicles.
Important Notes:
- Not for sale in California
- CS / CSL models require dedicated module variant – not compatible with base PCM
Why Choose MMX PCM?
- Real-time performance gains without ECU flash
- No permanent modifications
- Reliable power on-demand, with OEM-grade engineering
- Designed to coexist safely with stock ECU logic
- Beautiful fit-and-finish with premium materials
This is the ultimate solution for G8X owners seeking safe, reversible performance without compromising reliability or factory ECU integrity.
