Abstract
An engine control system for regulating operation of an engine having a throttle includes a first module that determines an intermediate parameter based on engine operating parameters and a second module that determines a pressure upstream of the throttle based on the intermediate parameter. A third module regulates operation of the engine based on the pressure. The engine operation is regulated based on a pre-determined relationship between a throttle position and an effective throttle area.
