Anyone have a copy of a GM Stage II tune?

 

I think they are a little bit different by the year

I found a link to hpt file online before but i cant find it anymore :x all i have is the pcm with the tune on it

 

I have one. Pulled from an 07.

 

05 Was different, 06-07 were the same (to my knowledge)

 

Actually, 07' was the one that was different.

Most (not all) 05' & 06' GM Stage 2 tunes are the same.

Now, when you are talking about GMS3 the 06'-07' PCM is the same, while the 05' is different.

 

I know that the 05's were different in the sense that the gas gauge was reversed. A full tank would should EMPTY and the more you drive the "more gas you get" lol

 

Haha, thats pretty funny. I never heard of that before.

 

I saw one in the hptuners repository.

 

Bingo. The 07 tune is different because the PCM is 32 bit instead of the earlier 16 bit PCMs, so the OS is essentially a little different.

Also as was said, the gas gauge reading.

If you have HPT just go on the repository. Or just go custom, the GM S2 tune sucks anyways lol.
