Abstract

A system and method for adjusting engine settings and/or calibrations is based on engine and/or vehicle parameters, and/or environmental conditions, and is further based upon a forecasted drive cycle, forecasted driving condition, vehicle vocation, vehicle geographic location, vehicle load, type of operation, season of the year, vehicle system or subsystem condition and/or operation, and/or other factors. An engine of the vehicle has an ECU configured to store and implement an engine control map. At least one algorithm is operable to determine an engine control map specific to an engine operating parameter, a vehicle operating parameter, an environmental condition, and/or an expected range of settings and calibrations. At least one device is configured to wirelessly upload to the vehicle the specific engine control map, and then load or flash the specific engine control map to the ECU.
