SNKEBIT Posted October 19, 2013 Author Share Posted October 19, 2013 Are the engines that much different? Link to comment Share on other sites More sharing options...
Moderator Wild and Free Posted October 19, 2013 Moderator Share Posted October 19, 2013 Not that the engine is different as it is the engine controls and sensors change with epa changes for emissions and the way it comunicates with the pcm changes with tranny and chassis changes from year to year. It is a simple 10-15 minute flash at the dealer but they will charge you an hour flat rate fee. Link to comment Share on other sites More sharing options...

Like you got federal emissions, California emissions, Canadian emissions, automatic transmission, manual transmission, SO vs. HO software, etc. I heard there is like 40 to 50 different versions of software.
