Does anybody know if the reading on the throttle opening (TPS voltage) given through the PCIII software is accurate for voltage reading (and TPS reset on a non-linear unit)? My initial observations correlate the throttle number output to the PCIII as the actual voltage from the TPS and that would be a pretty handy way to get that measurement.
Not sure, but you could throw a meter on the TPS, and then look at the screen from your PCIII to get the answer.
