I don't remember if I've ever posted or not, so here I am
I've got a '94 Z28 that I've been playing with and today while putting a new tune on it I got a "wrong message sent" from C.A.T.S. and now she won't stay running, my ses light flashes constantly, and I can't read anything from the pcm. Does anybody know what happened? Did I brick my pcm? What can I do?
