Abstract
A control system and method for optimizing power in a combustion cylinder of an engine. An ignition timing reference is offset during each learning interval. Differences in indicated mean effective pressure (IMEP) which result from the timing offset are calculated. When a determination is made that the offset timing reference is converging towards an optimal value, the timing reference is updated.
