I called Cobb last week and told them that my car was delivered by the end of Dec 2011 and it's a 2012. Then I told them I would like to give it a try since there is a 30 days return policy. They said that's fine.
I got the AP today and hooked it to my pc to update the firmware then connected it to my car. And it worked! my ECU was supported, I have it on Stg1 aggressive.
