Genral 7427 File questions

[Sledhead2]

Good Morning, Afternoon or Evening everyone, I have a few questions on 7427 files.

I am getting ready to use Turnerpro RT to do datalogging with a wideband. While looking at the tuner pro site and gearhead EFI, I notice several files are available for the 16197427 ECM

My Truck is a 95 and has a 4L60E trans.

Does it make a difference which one I use for data logging?


1) Does anyone know what the difference area or why there are several different ADX files and what's the difference?
A218 Trans1 $0d TP5 v250.adx
A218 Trans2 $0d TP5 v250.adx
A217 $0d TP5 v250.adx

2) Now my Bin file (BJYA) is list as a hacked file in the achieves, what is the need for hacking a file? I am thinking I need to start with a non hacked file.
