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?

Vaughan Posted June 20, 2022 Report Share Posted June 20, 2022 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% Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 21, 2022 Report Share Posted June 21, 2022 Change the settings below in Ethrottle setup too. If still no joy we will need a log. Quote Link to comment Share on other sites More sharing options...
JEDJET Posted June 26, 2022 Author Report Share Posted June 26, 2022 Adjusted settings as required. Still getting H-Bridge error. Attached log, starts up but just free revs so i have to kill it.

Adamw Posted June 26, 2022 Report Share Posted June 26, 2022 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.

JEDJET Posted June 26, 2022 Author Report Share Posted June 26, 2022 Hi Adam, We worked ended up changing Aux1 to High and it works perfectly. Voltage drop is due to small race car battery being v flat! Quote Link to comment Share on other sites More sharing options...
