Abstract:
1. A method for monitoring performance data for a motor vehicle, the method comprising: sensing a speed of an engine in the motor vehicle using an engine speed sensor; determining an engine torque from a torque converter stall performance map stored in a controller of the motor vehicle, wherein the torque converter stall performance map includes engine torque plotted versus vehicle speed for a plurality of gear ratios; determining an engine horsepower based on the sensed speed of the engine and the engine torque; sensing a position of an engine throttle of the engine from a range of engine throttle positions using a throttle position sensor; sensing a fuel consumption rate of the engine using a fuel flow sensor; displaying the engine horsepower, the position of the engine throttle, the speed of the engine, and the fuel consumption rate in real time during operation of the motor vehicle; and diagnosing an engine performance based on the displayed engine horsepower, the position of the engine throttle, the speed of the engine, and the fuel consumption rate.
