1992 - 1993 Information

donhall (corvetteforum.com) sent me this email he received from pcmforless.com:

"We can only disable the vats in the chip [on 1992-1993 C4s], there is a separate system to keep the car from starting. You will have to bypass that one also to completely eliminate vats."

I am assuming this is referring to the rest of the system such as passkey, etc.
