`A motor vehicle engine is controlled to reduce launch clutch heating. A first engine map is selected when the clutch pedal is between fully open and intermediate positions, a second map for pedal position between intermediate and closed and a third map used for the closed position. The first map provides reduced engine output for a given set of inputs over the third map allowing clutch input speed 62 to drop rapidly at launch t0, reducing heating, and the second map permits increased power over the third map to allow engine output to rise at an intermediate point ti as input speed approaches the clutch output speed 64 to counter driver perception of controller interference. Three maps may apply to sport mode and a two map arrangement omitting the power increase map may be used in eco or normal mode. Variable lift valves or turbo overboost may be used to alter engine output. Variable valves may be used to control engine speed while identifying an upshift event based on clutch pedal and gear selector inputs.
