Correct SBL for PCM

[nap1222]

Hi, cant find answer on forum where you guys look for correct secondary bootloader file.
Update wizard dont show it because PCM is tuned and shows incorrect software for the car
In ETIS I just find stock software, but dont know what SBL to use for GR3A-14C204-DJA

Mustang GT 2016 PCM calibration vbf files for GR3A-12A650-BTA

VIN 1FA6P8CF1G5327353

Car was modified and pcm flashed before, i want to get everything to stock tune

Thanks

Update: with help from support team i have correct sbl, but I cant flash PCM

Error of unknown module or bad seed key

How to find and manualy enter seed key?

Possible to update tuned PCM to stock?
