Just as the title says and I need it to be in HPT form. There isn't one in the HPT repository and there are subtle differences in the fueling systems and tables from 2002-2004 that I would like to be able to see.

Thanks

 

hey man we've got an 03 or 04 in the shop with the engine out....I'll double check the year tomm. Its going to be down for awhile though, but I think I can get you a chance to come grab the tune if you need it before its running.

 

29.88662 put that in your injector rate, I have the same ones as you. good luck.

 

That would be cool if it is an 03. I have stock 8.1L tunes for both and 02 and 04 from the repository so i was hoping to get an 03 for comparison.

 

You can dowload EFILive program for free, and there's an 04 8.1L GMC tune on holdencrazy.com

 

Thanks. Lots of questions here.
Curious how you came to this number?
Are you tuning with a wideband?
Are you running OLSD and is you AFR stable?
What do you have the rest if the injector tables (offset, pulse tables) set at?

 

Thanks, I might do that if I can't get it on HPT.

 

Just realize you said it's an 04 tune... Doesn't help me since I already have an 04 tune and 04 has a returnless fuel system. I was really hoping to see the differences between the 02 and 03 files.

 

what info do you need from the 03 tune, I cant get it to ya since I dl'd EFILive demo this weekend and Ive found an 03 tune

 

I wanted to look at mainly the Injector tables for an 03 8.1L. Sucks to not be able to find a tune in HPT so I could use the compare tools...

I think I am getting my stuff slowly worked out, it's just nice to have as much info as I can.
