Set VATS to 2 and 'write entire'

I checked what my PCM can use and write most supported entire OS
Since then no problem with XDF

Nope
Ur main problem is that u not reading
ELM327 can't flash PCM
For any changes with PCM firmware(like enable/disable efans) u MUST reflash it

ELM327 only for monitoring
To reflash PCM u need one of supported cables for PCMhummer software
Tunerpro only to redacting bin file
Upload/download bin -PCMhummer

HP-tuners has an option to lock customized firmware
Better to ask ur seller or use another HPT and it will show if it tuner-locked or not

Tuner pro needs XDF to work with bin (and u need hardware to reflash ur ECM)
If someone willing to share it cuz new cars has much more complicated OS and it takes a lot of knowledge to make XDF from raw data

Thanks man
It will help definitely

At least u resolve somehow )
There is a lot of bins onto GithHub
Choose by ur PCM hardware

As far as I remember ignition and injectors numbers not match between v6 and v8 (I mean pinout )

What PCM module do u use ? P01 P59 ?

I think its mostly for correcting speed info into digital bus
Trans itself working based on speed sensor that count prop shaft revs and not wheels

Gear ratios into tranny relates to gearset installed into it -how can you change them by reprogramming ?

Not all P59 has IAC driver to control idle speed (as far as I heard - most of them don't) I saw unsuccessful attempt on youtube where IAC driver chip was desoldered from p04 and installed to p59 But that man was very bad in soldering and probably overheated IAC driver Or maybe not installed all miss...
