The MMX PCM is an advanced engine tuning solution, using proprietary calibration on a standalone PCB that communicates in parallel with the factory ECU. This setup allows real-time optimisation of key sensor signals, enhancing engine performance without overriding OEM safety systems.
Developed over 12 months and tested across tens of thousands of miles—on dyno, road, and track—the MMX PCM delivers the ideal balance of power, drivability, and reliability. It’s far more than a standard tuning box—functioning more like a secondary ECU.
Each kit includes a custom-fit wiring loom for your specific vehicle. The PCM module is enclosed in a finned billet aluminium case for efficient cooling and comes with a carbon fibre mounting bracket for secure, clean installation.
