OK, so its normal to be off by one. Was just making sure. It wouldn't make sense to have a two different OS#'s for the same PCM on the same year, make, model vehicle.

So, which ones do you still need? I have many, but I figured most were already commonly floating around and supported.
So my current tune on the truck has an OS # of 02606494 and the holden crazy tbss stock tune has a OS# of 12606494. They are both E40 PCM. If I start from scratch with the holden crazy stock tune I wont have any problems will I? Thanks for the help all.
OS question. I have an 09 sierra 4.8l ly2, e38 and t42. I have looked at some of the other tunes on this forum, and I don't have the option of some of the parameters seen using same controllers. I'm assuming this is due to different OS. Being done controllers can I just download said OS and perform tune and download with operating system? Sorry for the nooby question. Awesome wealth of info on this forum, thank you in advance.
Some OS's are not compatible... there's a document showing year and OS's compatibilities, see attached:
Thank you sir.
What about trans?
Similarly to your questions in the other thread ... post your tunes (ECM & TCM) ...
Hi Guys, Does anyone have a stock Australian 2005 GTO LS2 auto tune please...
There are only manual ones at holden crazy.
I have to replace a HP 2 bar.
Do you know what OS this is. Would one of the other HSV calibrations do the job? e.g clubby,maloo?
