ABSTRACT:
An engine spark timing control system and method for addressing various engine output torque constraints. Preignition and knock concerns are addressed according to the conventional practice of calibrating spark control table, and the most limiting of the drivetrain-related torque constraints is referenced to such table to determine the additional retard, if any, required to satisfy such constraint. With this control, the preignition spark control table or any of the drivetrain-related torque constraints may be changed at will without violating the other constraints or calibrations.
