Abstract
An engine control system comprises a driver input module, a cylinder actuation module, and an active fuel management (AFM) module. The driver input module generates a fuel saver mode (FSM) signal having a first state based upon a driver input. The cylinder actuation module selectively disables at least one of a plurality of cylinders of an engine based upon a deactivation signal having a first state. The AFM module generates the deactivation signal based on at least one engine parameter and at least one threshold. The at least one threshold is modified when the FSM signal has the first state.
