    Default Dumb question...

    I was looking over the supported vehicles list, and noticed that the V1 does not support the 98-00 Vortec PCMs. Why is this? The newer LS2 PCMs are obvious (CAN), but IIRC, the 98 Vortec PCM uses VPW just like the LS1 PCMs.

    Just curious.

    I believe Ross said they had connectivity issues with the V1 and the Vortec PCM's, but not with the V2's even though they are VPW, So they were only able to make them work with the V2.

    He could explain it better, but he had a good reason.

    Yep, it was an issue with reading and flashing. You can still use a V1 to scan though.
