Thread: Will Holley 558-443 dongle work on Dominator?

  1. #1

    Default Will Holley 558-443 dongle work on Dominator?

    Just like the title says. Does anyone know if the Holley 558-443 CAN Bus dongle will work with the Dominator? Thank you in advance.

    Read "USB/CAN Communications/Dongle" end of page 4, and "USB Communications" beginning of page 5:

    Thank you for the reply. Dumb question, but I can't figure out where it plugs into.

    It plugs into the CAN Bus connector.

    I can't physically find the connector on my main harness. From pictures it looks like it's by the fuses/relays near where it plugs into the ECU, but the only plug I have is a large 2-pin which is different from the one on the dongle. Is there some sort of conversion plug I need between the two?

    I finally got all my cables and plugged everything in, but the ECU won't go "Online". Is there a setting within the program I need to change to allow the ECU to recognize the laptop though the CAN Bus?

    Do you have the latest version installed? Because I think it installs drivers to enable this function.
