It measures the RPM of your engine and the speed of the drum to calculate the overall gearing. It also needs the overall gearing to adjust the torque graph because it reports engine torque, which has been reduced by driveline friction. The actual measured rear wheel torque is higher than reported due to the gearing multiplication. The horsepower transfer is not effected by gearing, only friction.Bob
