What was said about the Corvette VATS is true. I posted a more in-depth look
at this a couple of months ago to this list. When working with a vette prom
you must flip a different bit. In all of these that I have done, I have
never needed to do anything with the code mask after after toggling from
VATS to NO VATS.
