Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Computerized Engine Controls: Notes
Conquest engines are equipped with Electronically Controlled Injection (ECI), a computerized emission, ignition and fuel control system. The Electronic Control Unit (ECU) controls the ECI system along with other related systems to continuously adjust engine operation.
All others use Multi-Point Injection (MPI), a computerized emission and fuel system which controls fuel, ignition and idle speed. The Electronic Control Unit (ECU), determines at which point each injector supplies fuel. The MPI system controls air/fuel ratio, ignition timing, Idle Speed Control (ISC), fuel pressure and purge control.
