For the most part the newer pcm's aren't that severe but still the same idea, there are likely 2-3 operating systems for 2011 cruze, 2-3 2012 cruze operating systems, 1-2 2011 Silverado/Sierra E78 operating systems, 1-2 2012 Silverado/Sierra E78 operating systems, 1-2 2012 Sonic operating systems, etc.
