Abstract

An improved control method/system for controlling engine speed (ES) of an electronically controlled engine (12) communicating over an industry standard data link. If the difference between engine speed and target engine speed exceeds a reference value ((ES-ES.sub.TARGET)>REF?), then the engine is commanded to operate in a torque control mode or a speed- and torque-limiting mode (64).
