Vehicle Calibration System: CALVIN
CALVIN was jointly developed by Ford Motor Company, Texas Micro, Inc., and EnGenius to perform calibrations on engine controller software. The task of calibrating engine control software involves changing data used by the algorithms that execute in engine controllers to provide optimal performance for a particular vehicle and powertrain. By investigating and setting literally thousands of variables in the engine control software, the calibrators find the proper balance between performance, fuel economy, and emissions. Calibrators also verify the performance of the vehicle in all operating environments, from extreme heat to extreme cold and high altitude.
