Update:
Ended up buying a E92 ECM from Junkyard from a stock 2019 Express Van so i would have a completely stock LV1 file to start with, now i gotta start tuning.

Going to post this stock file...

Chris,
ECM is E92 with a 12694524 OS from a 2019 Express Van with an LV1.
Yes this is for a swap into a ground up off road rock crawler.
The good part is the last "shop" that put a tune in there...

I have paid 2 different "Tuners" (one was a shop with a dyno) to make this thing run. And it's barely derivable.
Nothing special at all it's just a bone stock 2019 4.3L with a TH350, all i really...

What did you end up doing?
I have a manual swap as well an also have the problem of not revving over 4000.

Ditto, Looking for a stock LV1 tune here as well.

Got it thanks!!!!

Bringing this one back to the top.
I also need a tune for a 2019 with a manual but it does not need to be stock as I will be swapping over my tune to the 1269 OS.
Any 1269 OS for a manual will...
