What PCM does.
PCM works by using our in-house developed calibration running on our standalone PCB, which communicates in parallel with the factory ECU. This communication route allows the PCM to safely optimize a variety of electronic sensor signals in real time, interfacing between the engine controls and its sensors.
With multiple channels such as charge air pressure, ignition and fueling controlled by the PCM computer, the result is increased power and torque across the whole powerband of the engine.
We have carried tens of thousands of development miles of rigorous testing on our in-house dyno, on road and on track with numerous calibrations, across multiple cars and different hardware installations, allowing us to find the sweet spot for engine performance, drivability and safety.
Everything you need.
With 12 months of detailed development, our PCM is more than a 'tuning box'. The kit is complete, including a perfect fit wiring loom made especially for the selected vehicle.
Cooled by fins.
The unit itself is housed in a stunning billet aluminum case, finned to ensure adequate cooling plus a beautiful carbon fiber mounting bracket to affix it securely in your engine bay.
PCM vs ECU Calibration.
We're completely honest about this, the PCM calibration is not as sophisticated as a full ECU calibration. To keep the car smooth, safe and reliable, PCM's power levels have to be kept lower than traditional ECU calibrations. But of course, you'll love the power boost you get from PCM, combined with the drivability and efficiency gains.
