Any suggestions on how to raise shift limit to 8000 RPM. From 7500
Any help will be appreciated

No one ?
Are you trying to raise the rev limiter/ part throttle shift rpm / wot shift rpm?
Post your tune file
WOT and it shift at 8000 rpm on a 2019 mustang A10 stock tune so far might add 409 gears

yalls issues lie in the limiters and the OSS map, we have ours shifting at 77-8100 with no issues
this looks like the table under wot shift pulled from a 2019 a10 the other day

Also am interested in changing shift points ive upped all the limiters that I can possibly think of any help will be greatly appreciated still shifts at 7500
Since it appears this thread got hijacked, bringing it back to the original question. Is the table that sportinawoody posted the correct one to increase shift points at WOT?
I found the newer 6F55 doesn't respond to those WOT tables. I had to go into the OSS tables for Normal and Sport to actually tweak my shift points. I personally found that 1st and 2nd gear has a lot of shift overlap, meaning if you are commanding a 6500 RPM shift in 1-2 and 2-3, it may go past this and bang the revlimiter for the first few WOT shifts. After maybe the 3rd time or so, something in the TCM must have learned/adapted and the following WOT shifts will be closer to what you're commanding... except in 1st and 2nd gears where there's about a 400-500 RPM (engine) over-run. I think it is because the torque converter can't lock up in 1st, and can't lock fast enough in 2nd... so 3rd thru 5th gears work as commanded right away in the OSS tables. My 2014 SHO never had this problem, I simply worked the WOT tables like sportinawoody posted and all was well. My 2017 Fusion Sport and 2018 Explorer had to be tuned the way I described above. YMMV with the 10R80, and I'm eager to hear the right way as well since I am thinking about getting an Explorer ST that has the 10R60.
Have you messed with your max acceleration rate? It may not be defined in that specific ECU i can't remember if it was or wasn't. I'd be curious to know if that's your issue with over shooting the shift. But you are right it will learn the shift as i have had it do exactly that, but opposite, where it shifts early and then learns to shift later. Max accel.PNG
Yes I have increased that value. I did the same on the 2014 SHO. In fact all I did on the SHO was tweak the WOT tables and it was good to go. I would do this back to back on the track without problems. With the 17 and 18, it would bang against the limiter and hang up on the shifts for a pass or two then become normal. I even copied the SHO settings over without making a difference.
Any updates on this?
Bump
This is my trans tuning on my 19 A10. Shift points are perfect at 7750rpm if you use compare you can see the changes.
Im having this problem too with my 10r80.
It will not up-shift and go into the next gear at WOT. Then limp mode for a second or two.
How can I fix this?
