Awesome information! Just scrolled the all the possible obd pids and found the map psi and the vehicle load % pids. Set up a screen showing those, plus speed, rpm and throttle position command value and will experiment with it. Fingers crossed that there is a usable method to make the throttle stop testing method work. Will be over a week before I have results as am leaving in a couple days for a short trip in my old RV.
