Shift Point Adjuster not working?

[Ninety8C5]

I was just playing around with a 98 A4 Vette tune changing the rear end ratio and tire diameter and the 'Shift Point Correction' didn't change. I was using the new 7.5.1 release (Build 21). I kinda remember this working in a previous issue but don't remember which. Or is it that I ain't doing something right (I've being doing a lot of that lately)? :nixweiss:

I input old & new tire size and diff and the 'Adjust by:' stays at 0.00. Is there somthing else that needs to be selected/clicked on or should the 'Adjust by:' change as you input info?

I just tried several other years and it looks like it doesn't work on 1997/1998 tunes. On other years the original tire size and diff are filled in. On 97/98 cars no original data, but even putting in old & new data doesn't cause 'Adjust by:' to change.
