Abstract
A microprocessor engine control for an internal combustion engine powered truck is provided with a clutch priority engine speed control by the inclusion of a clutch pedal switch for sensing incipient clutch engagement at vehicle launch. The microprocessor executes an algorithm that takes control of engine speed away from the driver until the launch is successfully completed. The algorithm causes the engine to operate at a speed that has been predetermined to minimize wear and tear on the powertrain. The algorithm includes a false start feature that resets the alogrithm in the event of an aborted launch.
