ABSTRACT:
A system for controlling ignition timing has a detector for detecting load on an automotove engine and for producing a load signal when the load is larger than a predetermined value. In response to the load signal, an advance angle is provided. The advance angle is added to a basic ignition timing to produce a desired ignition timing. The system operates to excite an ignition coil of the engine to form a spark at a spark plug at the desired ignition timing.
