Posted about my findings with rev hang in another thread but got no response - this one is more fitting I think.
Based on some videos online of people disconnecting their upper clutch switch to get rid of the rev hang (on a Fiesta and Veloster), I figured this switch may have something to do with the rev hang. First I tried simply disconnecting it, but the gas became super sensitive and the idle weirdly got higher. I did not drive it though so need to revisit this.
I also made a circuit to change the behavior of the upper clutch switch, so that it would match the lower switch in terms of its signal. However this made the car almost undrivable and didn’t fix the rev hang.
I believe it’s really just a matter of tuning the ecu. It’s unfortunate that when I’ve asked around, no one seems to know if it’s possible, or hasn’t tried looking. I wonder if a lot of people have DSGs so there isn’t an incentive to try to cure this problem. Until someone figures it out I will be holding up traffic with my 1 to 2 shifts
Anyone else have some insight? I know we can deal with it but it would be great to solve this problem at the source.
