Thank you.
I have another PCM I picked up from the junkyard but didn't pay attention to what year suburban/yukon it was taken out of.Originally Posted by 1project2many

I'm looking for the same.
I'm looking for the same XDF file.
I need a matching xdf file for my 03 5.3 dbc 12579405 is my bin i need xdf for that bin or a new bin and matching xdf to write to my 03 pcm to make it run with no vats .
Will this work with a 03 Escalade
Anyone happen to have a 2003 2500/3500 or higher class pickup or SUV bin for 8.1 and dual tanks? It should be OS 12579405 (most likely) or 12593058 (unlikely but would make my life much easier) with fuel segment 12577990. Nothing else matters as far as I'm concerned, I don't even really care if it's an 8.1 it's just that that seems to be the only vehicle I have found this dual tank fuel segment on. I have two examples in HPT format but I need it in BIN format and I do not trust any of the websites I've seen claiming to sell an HPT to BIN converter app.
