A system for controlling an engine in a vehicle according to the principles of the present disclosure includes a fuel control module and a valve control module. The fuel control module controls fuel delivery to a cylinder of the engine. The valve control module closes an exhaust valve of the cylinder when fuel delivery to the cylinder is disabled during operation of the vehicle and exhaust gas has been exhausted from the cylinder after fuel delivery to the cylinder is disabled.

A transferable electronic control unit having a non-volatile memory that retains values of learned correction factors for control parameters used in adaptively controlling the operation of a vehicle is disclosed. The electronic control unit receives an identification signal from the vehicle in which it operates. By comparing the value of the received identification signal with a stored value identifying the vehicle operated when learning the values of the correction factors that are stored in non-volatile memory, the electronic control unit determines whether or not it has been transferred between vehicles. When a transfer between vehicles has not occurred, the value of the learned correction factors stored in non-volatile memory are used to begin adaptively controlling vehicle operation. When a transfer between vehicles has occurred, initial or mean values for the correction factors are used to begin adaptively controlling vehicle operation. As a result, the electronic control unit can be transferred between vehicles without causing malfunctions in vehicle operation.

In a method of traction control, fuel injectors are selectively disabled to unfuel respective cylinders of an engine to reduce engine torque output. The method provides for limiting the number of cylinders that can be disabled for acceleration spin control based on engine and vehicle operating parameters to improve traction control performance and provide protection for the vehicle catalytic converter.
