1. A method of controlling torque output of an engine, comprising:
- calculating a desired air-per-cylinder (APC) based on a torque command;
determining an effective throttle area corresponding to said desired APC based on a non-dimensionalized model; and
regulating a throttle based on said effective throttle area.

Abstract
A method of controlling torque output of an engine includes calculating a desired air-per-cylinder (APC) based on a torque command and determining an effective throttle area corresponding to the desired APC based on a non-dimensionalized model. A throttle is regulated based on the effective throttle area.
