Ok, so Im in the middle of a 85 C10 LS swap.

Ive got a 5.3 with a 4L60e with ECU from a 2006 2WD Tahoe w/ FlexFuel. Im putting in it. Paid a grumpy old guy off LS1 tech to delete VATs.
I dont think he did it right or did it because my truck wont crank longer than a cycle then die off. Even if its deleted I want to know for sure.

So here I am, trying to learn all this on my own.

Idk what ECU I have. Im pretty sure its a L59 just due to it being from the 2006 tahoe I pulled all this from.

My question is, before I brick my ECU.

What BIN should I use and what XMP?? Ive been googling and youtubing for a few weeks and have no info on how to find out exactly what ECU I have, how to find out or what BIN/XMP to use with out bricking it.

So if someone can explain how to know exactly what BIN/OS/XMP file to use for my ECU.... And get me going I can figure out the rest on TunerPro.

I just cant seem to get the info on how to grab and download the right files to get started.


Thanks in advanced.
