I've been looking around the forum with no answer, My 2012 CTS V does not have the 2 bars speed density OS. and when i go to the tune repository 2009, 2012 and, 2014 don't have it but 2010, 2011, and 2013 it is available. Is there a reason for this?

Changing to 2 bar is pretty straight forward, when you apply the patch from the OS selection screen it will redo the VE tables. As for the tune repository being a mess I have no clue

that's a good question as my 2014 doesn't even have that patch available in the drop down OS patchesOriginally Posted by RMG
I understand the how to, I just don?t have the option
It's because the 2013 is special. lol

Seems no one has an answer for this, I really didn't want to summit a ticket for what is probably an easy answer. But i don't understand the difference per years in the same car
Have you tried downloading a few stock 13 LSA files off the repository? Its possible a different OS same year has the upgrade as an option. 2006 Trailblazer SS's are like this. One OS has the option to upgrade. the other doesn't.
But yes there are odd OS's sprinkled thoughout GEN 4 that do not have a option for upgrade. I hope they add it for you. I heard they weren't doing that anymore.

the problem is for my 20122012 Operating system.png, the 2013 seems to have the OS. Is there any way to change the operating system from 2012 to 2013?

That is exactly what I see as well when I go to my OS
