Latest project swap. 2010 LS3 from 2010 camaro 6 speed. As I look at the programming in the ecm, it shows that vats is not active, so how would a person shut it off if it is showing not active? Of course it does not start the engine either. Any ideas. has anyone had this issue. we have all relays accouted for etc.? Thanks guys. I'm high maintenance I know
