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 combination with an engine air flow signal and/or a lubricant level signal during predetermined engine running conditions. These predetermined running conditions include low speed, warm up, overhead, cruising, and overspeed engine running conditions, as well as a low lubricant level condition. The ignition control system is also capable of detecting and responding to abnormal combustion running conditions and setting and optimum spark advance during the starting of the engine.
