Abstract
An engine ignition timing control system and method wherein a timing module associated with a given engine includes a read only memory and circuitry for generating information related to engine crankshaft rotation. The module memory is programmed with information relating piston position to crankshaft rotation. The crankshaft rotation and piston position information is made available to an on-board ignition computer for precise control of ignition angle. Also disclosed are a system and method for separately programming the module memory associated with each engine as a function of the piston mechanics of that engine.
