    Default Unrecognized PCM problem

    Can someone tell me what the problem is? I'm trying to connect and read a PCM from a 2003 ECOTEC in a Cavalier. I can connect the scan tool and read data but when I try to upload the tune, I get the Unrecognized PCM screen. The VIN and OS appears but I can't read anything else. This should be a supported PCM and I am running the lastest build.
