A technique for reducing a parasitic DC bias voltage on a sensor monitors the parasitic DC bias voltage on a first element of the sensor. A controlled bias voltage that is applied between the first element of the sensor and a second element of the sensor is then modified to substantially maintain the parasitic DC bias voltage at a desired potential.

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.
