Ahh the knock detector plug in. Yes I've seen it. Couldnt calibrate it because you can't go full throttle in park? How did you get past that? I am really after the PID for knock and this Torque plugin uses a method that tries to measure it indirectly. I get how it works in theory but am not sure how accurate it would be? I do actually have a PID that I believe is knock but I don't have scaling or equation for it. I use it but am not 100% sure it works either.
