Having dramas with E-Throttle on younger brothers’ car, managed to get started was idling approx. 2000RPM. 

Changed something (no idea what) now on start-up car tries to rev to redline uncontrollably.

Getting Error 16: H-Bridge Polarity is Reversed on E-Throttle calibration, have tried every setting change under the sun, tried pin swapping nothing can get me past this point.

 

Ideas?

your idle min clamp is set to 10%

I wouldn't expect you to need more than say 7% E-Throttle to idle so set your min to something like 2% and max to something like 10%

Check the ecu connector is pushed home all the way right across the whole width (ie its not bent out at the ends).  Your battery voltage drops to 5.4V as soon as the throttle tries to move so you have a bad main power supply somewhere - often with the nissan ecu's its when the connector isnt fitted right. 

Im also suspicious your throttle may be working backwards - so test it first, it doesnt need to be running.  Put the E-throttle in set up mode and move the pedal.  Look at E-throttle target and check if TP follows it.  If it goes in the wrong direction then change the Aux 9 active state to the opposite.
