    Horsepower vs hill gradient problem

    You can. The RPM is used to calculate the vehicle speed. They already know the mass. They also factored in coefficient of drag and frontal area. I was wrong for using "rpm change"

    Horsepower vs hill gradient problem

    Thanks for the replies. Yes, this software uses some formula against the speed of which the RPM climbs, Each sample records the current RPM taken at that time For example, With gear ratios and wheel size factored in it then figures how much energy it would take to move the RPM of a vehicle...

    Horsepower vs hill gradient problem

    So, I have a car I'm tuning using a road dyno software. This software basically uses the gear ratio of the car, it's total weight, and the speed it moves the RPM to determine it's power output (HP and Torque) In order to use this software a flat road is needed. That works well and is very...
