A system for controlling fueling of an internal combustion engine includes a receiver associated with the vehicle, such as a GPS, GLONASS or LORAN-C receiver, operable to receive radio signals relating to vehicle location, a fueling system responsive to fueling signals to provide fuel to the engine and a control computer with a memory having a number of different engine fueling maps stored therein. The control computer is responsive to the radio signals to determine therefrom a geographical position of the vehicle, retrieve an appropriate one of the number of engine fueling maps from memory which corresponds to the geographical location of the vehicle, and provide the fueling signals according to the appropriate one of the number of engine fueling maps. In an alternative embodiment, the system includes a communications transceiver operable to transmit either the radio signals or the geographical location of the vehicle to a remote computer system, wherein the remote computer system is operable to determine an appropriate engine fueling map, based on the geographical location of the vehicle, and transmit the engine fueling map information back to the control computer for fueling the engine in accordance therewith. In either embodiment, engine fueling maps corresponding to at least a low emissions fueling mode, a fuel economic fueling mode and a high engine output fueling mode are provided for fueling the engine when the vehicle is located in an urban, rural and hilly geographical location respectively.
