    ok never mind it progammed finally. I have one question though, If the flashscan interface is too close to the pcm , while tryin to reflash will that cause repeated errors. The reason i say this is, i have my desktop and not a laptop so i had the interface on top of the hood, right on top of the pcm. Could that cause errors?

    I wouldnt think that would be a problem. Maybe your desktop pc was making a ground issue? I dont know.. Glad you got it working though.

    Shouldnt be an issue, before I borrowed my friends laptop I was using a desktop in my garage to flash my TrailBlazer I6 and the FS was right over the PCM (it is on the drivers side for the LL8) and never had an issue.

    Nice to see fellow users talking about 98-99 Vortec stuff. I would find it interesting if any of yous guys would have any further info to post up more often. I have had plans for my 99HOE ever since the support became availible alas, I haven't even read that pcm with my V2 yet.

    I just had the same issue on my 99 Silverado (K1500, not GMT800) and I could not get it to take after 5 attempts....any idea what's causing this issue? I've had no issues reading them, just writing this one. Any help is appreciated. Thanks.

    Find the *.blx file in the folder \My Documents\EFILive\V7\Bug Reports.
    The *.blx file will have the form:
    Download_YYYMMDD_HHMMSS.blx where YYYYMMDD is the date and HHMMSS is the time that you attempted to reprogram the PCM.

    Please send that file to me at paul@efilive.com. Include a reference to this thread in the email.

    Regards
    Paul
