I am trying to apply a 2bar operating system on a 2004 LS1 C5 Corvette and I am having a little problem.
I have the 2bar tune all worked out and I am ready to do the entire write. I hit the entire write in the drop down menu and applied the 2 credits for the 2 bar tune. The tune didn't automatically write at that time for some reason. I waited and nothing happened so I hit the entire write again.
Now it just says security acess denied and it will not go any further. I wrote a old MAF tune to it and it worked just fine, but every time I try the 2bar it freaks out.
HELP!
