A system for controlling internal combustion engine performance in accordance with driver behavior includes a vehicle control computer operable to receive a plurality of vehicle operating parameter signals and control engine fueling based thereon. In accordance with an operational status, or an operational state determined over a predefined time interval, of one or more of the vehicle operating parameter signals, the system is operable to control available engine performance. Both the operational status and operational state of the various vehicle operating parameters are the result of the manner in which the driver operates the vehicle. The control system of the present invention is thus operable to reward/penalize driver performance by correspondingly adding/subtracting available engine performance in the form of available engine output power and/or available vehicle speed. Preferably, subtracting available engine performance occurs automatically, and adding available engine performance may be either done automatically or according to driver demand.
