An electronically controlled compression ignition engine is connected with an advanced cruise control system. The advanced cruise control system is capable of measuring distance to a vehicle or other object in front of equipment that is power by the compression ignition engine. Signals produced by the advanced cruise control system, at least in part, are used to determine the power output of the engine. In the event that the electronically controlled engine receives no signals from the advanced cruise control system, the electronic control may disengage or disable the advanced cruise control.
