Abstract
A torque control system for an engine includes a first module that estimates a first engine torque based on an air-per-cylinder (APC) value and a second module that estimates a second engine torque based on a manifold absolute pressure (MAP). A third module determines a desired MAP based on the first engine torque and the second engine torque. A throttle opening is regulated based on the desired MAP.
