Thread: Speedhut & Dominator EFI

  1. #1

    Default Speedhut & Dominator EFI

    So long story short, is there anyway to make the gauges work with the Dominator or will I need to run two separate sensors?Have a full setup of analogs that I'd like to have datalogged if possible.

    Analog gauges would require separate sensors. If you had digital Speedhut gauges you might be able to get them to talk to the gauge output from the Holley, but I bet you'd need to order them that way. I don't know if Holley has published the gauge specs or not. If they have, then Speedhut probably knows how to speak Holley.

    I'll call both Holley and Speedhut tomorrow. Are there sensor splitters to hook two separate plugs into the same sensor? Only needing fuel pressure, coolant, oil pressure & temp.

    Were you able to get an answer to this? Andrew
