Abstract
An engine control system includes a coefficient calculation module that selects one of N coefficients based on an AFM selection by a corresponding one of N users. A switching torque calculation module calculates an adjusted active fuel management (AFM) switching threshold based on the one of the N coefficients, a maximum torque of an engine, and a default AFM switching threshold.
