Abstract
An automatic calibration selection for an automotive control system allows the use of one basic electronic control unit (20) for a family of motor vehicles. In each motor vehicle, a unique valued resistor (10) is located in or adjacent to the wireharness and near the electronic control unit connector (12). This resistor (10) provides an input to a voltage divider network to select a voltage value representing the particular control parameters for the vehicle. The voltage operates to address (24) a read only memory (22) to place the proper calibration constants in the electronic control unit (20).
