1. An engine control system for a vehicle, the engine control system comprising:

  • a coefficient determination module that stores N coefficients, each corresponding to a respective active fuel management (AFM) selection by a different one of N users, determines which of said N users is operating said vehicle, and selects one of said N coefficients based on said determination, wherein N is an integer greater than one; and

    a switching torque calculation module that calculates an adjusted AFM switching threshold based on said one of said N coefficients, a maximum torque of an engine, and a default AFM switching threshold.
