Need help finding right files for TunerPro RT

Hello, so I have TunerPro RT installed and have my ALDL cable so that I can plug into my computer for data logging. The problem is I have an early 90's 350 that was swapped to a 90-92 TPI setup and installed in an 1985 k5 blazer. I'm a little confused as to what files I would be looking for TunerPro rt as I cant just reference the original vehicle for the proper files.
Could somebody possibly point this newbie in the right direction as far as what files I"m looking for?
!990 350 V8, 90-92 MAP TPI setup, ecm 1227730, 700R4 auto.
Thank you in advance to anybody who can help me here.

You need a "acquisition data" file aka adx loaded into TPRT that you can find at the following link...

Thank you for the info, I managed to get the adx file and sucessfully connect to the ecm for the first time. Again thank you for pointing me in the right direction to get started, much appreciated.
