ABSTRACT:
An ignition control system for an internal combustion engine which includes a microcomputer which operates to control the ignition timing in response to engine speed and engine temperature signals individually and in preselected combinations with an engine throttle or air flow signal during predetermined engine running conditions. These predetermined running conditions include low speed, warm up, overheat, cruising, and overspeed engine running conditions. The ignition control system is also capable of detecting and responding to abnormal combustion running conditions and setting an optimum spark advance during the starting of the engine.
