Hey all.. First and foremost, a big thank you to everyone involved, what a great gearhead community.
I'm working with a 2000 Yukon xl 5.3l 4x4 engine and 4896 pcm. I have used pcm hammer (what an awesome tool) worked perfect with my autel maxi flash elite.
From what I get, the OS that I have doesn't have support and I need to reflash the OS as well as the calibration. From reading, I believe I need the 12212156 or the 12208322.
I have tried to used the OS and xdf in post # 2 here

but am having problems. It keeps coming up as php file. Sorry for the questions on the first post...any help in the right direction would be much appreciated..
