yep. With a stall it's very annoying. Hell, even with the stock stall it's noticeable.

Ok, I did a segment swap from 60 to 80E as well and I don't have any issue with this. I'm not sure why but maybe this?


If I lift me foot pretty good the TC unlocks, but not with minor movements.

Mine always does this. What I heard was the 80e unlocks with under five percent throttle. Nothing you can do about it. There is some way to make it run on a 60 tune but I have never tried.

all of us segment swap guys suffer from this afaik . zippy may have a fix for this as i brought it up one time and he had an answer for it.

doesent bother me too much , most of the time im in od its on the freeway so Cruise control takes over.

my stall was a bit loose and it got somewhat annoying but i dont drive my truck often so living with it is fine for me.

curious as to how this making wiring changes will do ? if you make it think its a 60e than how does it compensate for the other speed sensor?
