no worries. im actually going to test that range switch now in my car to see what it does to the tapshift function.
ok, so i my car if i enable the parameter is makes no difference, but if i change D9605 from 6 to 4 i lose tapshift. I can still see the request come through but it's ignored.
the shifter in this car however is just PRND, then it goes sideways (holden) to enable tapshift.
