A digital electronic spark timing system has been developed and placed in production for use on the 1978 Oldsmobile Toronado. This system consists of an ignition distributor which contains a magnetic pickup and ignition module, a coolant temperature sensor and a controller package containing electronics and a pressure transducer. Engine RPM, manifold vacuum and coolant temperature inputs are used to derive and control the engine spark timing.The controller electronics design is based on a digital microprocessor, custom designed to perform engine control functions such as spark timing, exhaust gas recirculation, idle speed, etc. The system design criteria includes data storage and calculation capability, automotive sensor and actuator interface, flexibility and accuracy.
