Im trying to help a buddy out, and I cant for the life of me figure out what, where its cutting fuel at. Its at 6200 rpm it seems. I turned off TM, and it still did it. Any help. Here is a log and the current tune....
Around frame 250

Looking at the tune, it looks to me like the WOT 1>2 shift is set at 6150. That wouldn't cause fueling to be cut, but that would keep it from winding up higher.. The 2>3 shift is set for 6200 RPM, also, a little farther down that screen.
EDIT : Oh, yeah... I'm talking about D0941 and D0946 for those shift RPM's.
{B5401} is set at 6300 which is within a nats whisker of the max revs in your log.

I Think I went back and lowered some of it, I had to send him on his way because I couldnt figure it out that day. So I may have lowere b5401 down a bit to keep him in a safe rev limit zone. In case of some sorta failure etc.
Edit.... So b 5401. Second gear being set ar 6300 may be giving me problems? Not sure if I played with that table much honsetly.
Lowered the shift points to send him home. No point to keep it on the rev limiter daily driven.
Lowering the shift points is a good thing for now (until we can get this figured out).
