ECOTEC
ENGINE MANAGEMENT SYSTEM
The Ecotec's engine management system computer precisely controls the ignition and fuel injection system based on feedback from two oxygen sensors. The engine control Module (ECM) computer manages many additional system integrated functions such as on-board diagnostics, traction control calculations that adjust engine spark & the electronic throttle (ETC) to avoid wheel slip, and advanced cruise control logic. An added feature provided by the ECM is the monitoring of crankshaft movement,automatically cutting off power to the starter when the engine is already running.
