Can one get throttle position data from durametric with just the ignition on. I want to be able to verify that the full range actuation is available and adjust stop(s) prior to ever running the car. Will this plan be messed up with the automatic TB calibration sequence?

Yes I have made cable cam measurements. I am trying/planning to verify throttle pedal set up in this manner once I get there.

Yes....at present I am not able to just try it...
