I'll try to get you the best data that I can.
When you say "pedal" which of the pedal PIDs do you mean? The thing that behaves the most like a pedal is the one labeled throttle manifold and goes from about 15% to 81% in range. But there's also those other pedals with behavior that I don't understand.
Is the test to be done in fixed gear? Gear 2 or 3 would work, any preference? I'll try to do both, for comparison.
I'll also check what other other mode 21 Toyota PIDs may be available related to the pedal and throttle.
