An engine management system for regulating fuel delivery to an engine. The system has a primary engine control unit (ECU) and a secondary ECU interconnected by a switching system. A microprocessor in the primary ECU receives signals from primary sensors to regulate the injectors to deliver the proper A/F ratio. In the event of primary sensor failure or computer problem, the microprocessor relies on a selected alternate sensor input. Secondary sensors “fine tune”the control signal from the primary ECU. Switching to the secondary ECU is automatically accom...
An engine management system for controlling fuel delivery to an internal combustion engine having fuel delivery apparatus comprising: (a) a primary engine control unit including a microprocessor, said microprocessor being connected to first sensing means to receive and process signals representative of first predetermined operating conditions and providing an output signal to said fuel delivery apparatus and a control signal indicative of the operating condition of said primary engine control unit; (b) a secondary engine control unit including a micropro...
