Isn't MAP an indication of load? As in, on and the same? And yes, I can tell an engine by its exhaust, but what does that have to do with anything?
Also, can you please explain how load and MAP are used to create the chart? I'd love to learn how dyno testing is done. I always thought they just had a tool to measure and vary torque while they measured fuel consumption at different RPM.
