evinX Posted August 18, 2019 Share Posted August 18, 2019 Any ideas why my na auto seems to downshift and not want to pull happily at 50. Sometimes it changes gear up and down before gassing it to get it upto 60. I have done the pink wire mod. Drives fine and changes geaes fine until im sitting in a 50 zone.

evinX Posted August 28, 2019 Author Share Posted August 28, 2019 Just to update, got a clean working ECU and the supra drives normally again. Opened up the old ECU and behold 2 leaky electrolytic capacitors. Dont seem to of knackered the board. Going to get my dad to refurb it for me Link to comment Share on other sites More sharing options...
