Abstract
A torque control system for an engine includes a throttle plate having an adjustable throttle position to regulate a first mass air flow into the engine. A control module determines a first mass air flow into the engine and monitors an engine speed. The control module calculates a volumetric efficiency of the engine based on the first mass air flow and the engine speed and calculates the desired MAP based on the volumetric efficiency.
