CMD Module by Dynojet - Petrol Engine Tuning

The Dynojet CMD (Combustion Management Device) is designed to optimize the power of your OEM forced induction vehicle, while retaining the factory engine management system. The unit plugs directly into your OEM wire harness and intercepts signals between various sensors and the ECU. In most cases the Mass Airflow, Manifold Pressure, Throttle Position, Crank, Cam and each injector are captured and processed by the CMD to enhance each combustion event.

Typical Gains show 12-36+ HP at the wheel
