    No pcm connection

    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?

    Based on what you describe, it seems very likely your PCM is bricked.

    If it turns out your PCM is bricked, shipping your PCM to TunerCats to have the flash chip replaced is a low cost repair option. tc@tunercat.com

    Does the LT1 version of TC have complete programming or recover pcm options?
