Default TerminatorX wont shift anymore

So, this has been driving me crazy for a while now. It's a normal terminatorx(not the max) using the "race" trans in the trans icf, th400, operator shifter with air shift. Right after they released the terminatorx software with the new trans and traction control I set it up, and it worked great I have a datalog of it working. But something has changed, and it won't output the shift, it works in the output test, and if I use a shift override it works. But I can't get it to shift automatically. The shift timer also never starts which I think is the main issue even though I'm not using the time-based part of it. Very little in the tune has changed on that side of it. I have attached a zip file with 2 datalogs and the tune, and a tune from a few days before the datalog with the successful shift. I'm not sure what to try next, I've moved the shift parameters all around. I even disconnected the 5" dash because that was the only major change I can remember. I can set up a normal output to go by rpm and it works, but I lose some of the functions I'm sure could be recreated with adv tables. but it worked before, so it just drives me crazy. The datalog and tune that worked is from 10/18/23. Any insight will be appreciated

I have had that happen before and had to add the shift master enable for it to work.

Thanks, I'll see if I can get an input to try that.

Wanted to update this. Went to the track a couple weeks ago and it still wouldn't shift; I really didn't change anything so didn't expect it to. So, I just manually shifted it. Went back to track last night, set up a normal custom shift output and it works as I knew it would.

Little history- This car has always felt funny to me, and I've really been scared of it, first pass ever with no power it pulled the wheels up about 4 feet, of course nobody was filming. I finally fixed some stuff in the suspension and felt comfortable enough to put it on the chip last night, only at 2800 rpm lol.
But the funny part is on that pass the shift timer started working when it got to 5200 rpm. So, it looks like it has to be on the chip before it will start the shift process. In the old log I have of it working I didn't launch it off the chip, but I had put it on the chip about 12 secs before I went wot. When it wouldn't shift, I knew the tbrake reset the shift so I was hitting the brake before I went so that it knew it was in 1st, but if this is correct and not just a fluke it has to be on the actual 2 step before it will start.
Also, even though the trans icf output wasn't even pinmapped the timing offset from that icf pulled timing after the shifts.
I hope anybody who cares can understand this

I looked at the output from the trans icf shift single out and it for sure worked. So maybe the 2 step is the key. I'm gonna try to add a screen shot for anyone who cares
