ECMLink is a management system for the factory engine computer (ECU or ECM) installed in 1990-1999 Mitsubishi Eclipses, Eagle Talons and Plymouth Lasers. Mitsubishi_Eclipse These cars are turbo-charged 4-cylinders running either AWD or FWD and either manual or automatic transmissions.
ECMLink has two core components. The first is a chip replacement device that goes inside the car's ECU. This device adds full reflash capability to ECUs dating back to the late 80s!! The second is a laptop application that talks to this chip via the diagnostic port in the car. The user is able to adjust a variety of parameters used by the ECU to run the car's engine. These changes can be made to optimize the performance of the engine or to adjust for changes the user has made to the engine's configuration.
