That OS isn't the stock OS anymore. You can only use the segment swap with a stock OS.
So the upgraded OS that is on that file won't work. You can flash back to stock, do the segment swap, apply the upgraded OS to the new segment swapped file, then copy over all your tune information into that new file.
Excuse my ignorance...just now getting into tuning, under "tune details" in the controller's tab it says "operating system 12606807", but under the OS tab, it says "Speed Density-2 bar OS: 1252065" just need help finding a stock 4l80e tune with the correct OS # to do the segment swap. I can't seem to find one in these forums.
The stuff in the OS tab are things that can be applied, not what's applied already. The Tune Details window is what it actually is. POST YOUR FILE and it doesn't take three weeks to solve things like this.
Thank you for that file will try it in the morning
