    can't read vehicle MVPii

    2003 GMC Yukon XL Denali. I keep getting this no matter what I did. I had read it before with the older version of HP Tuners but we did not lock it. I did have to remove it from the truck since the battery went dead before the download completed.

    incidentally it doesnt read with bluetooth only with the usb plugged in?

    ecm is tunerlocked ie seed/key is not stock.
    It doesn't have to be perfect, it just needs to be done in two weeks...

    A wise man once said "google it"
