    The name "Speed" is reserved for the Holley EFI Transmission ICF. Your VSS is from the custom Inputs/Outputs ICF.
    You can configure the EFI software's Data Monitor (click "E") to include that custom created channel into one of the screen views.

    Enter the Data Monitor/Datalogger Edit screen ("E" button at top left corner),
    and "drag & drop" the custom channels over to the Data Screen/Log View lists.
    You need to scroll to the right to select the custom created channels.
    May God's grace bless you in the Lord Jesus Christ.

    As always thanks Danny. Can I make the Digital Dash to display that info as speed? Regards.

    Yes. Scroll all the way down the "Value To Monitor" list for your custom created VSS speed sensor input.
    Custom I/O will appear on the Digital Dash list when synced to your ECU. Enter the "Customize" mode (function screen).
    Read page 13, "Adding Gauges", in reference to adding a gauge to the Digital Dash. The "channel" list is Step 3, page 13.

    Appendix A (Above the listed channels on page 42 & 43.)
    Below is a list of 283 values that can be monitored. Any user programmed I/O values will
    appear in the list, in addition to these once the Dash has been connected to a Holley ECU.

    I'm about to wire my VSS and I'm seeking clarity on this. The VSS pigtail has a black & yellow wire. Confirming black can go to any to chassis ground and yellow goes to any one of the following pins on my J2: A21, A13, A4, or A30? I'd prefer not to use output ground for the VSS.
