Thread: Terminator software V2 - V4 update.

  1. #1

    Default Terminator software V2 - V4 update.

    Hello. I want to update the firmware in my Terminator to V4. It's out of the truck right now. I was wondering if I could simply supply a solid 12V source to the unit, to the switched 12V and to the ground, and hook up the USB and upload? Also, is there any known issues to doing this, as I also bought the 3.5" controller, and I understand that I have to do the update anyways to run it? Please let me know what you think? Thanks.

    I wouldn't do that. I'd install & wire everything properly.

    When doing something as important as an ECU firmware update, my laptop is fully charged, and my vehicle battery trickle charger is on (LINK).
    Remember, you can not lose battery power or laptop communication during an ECU firmware update. If so, the ECU will have to be sent to
    Holley, to be reflashed at their end. ECU firmware updates must be performed very seriously, and with a properly functioning laptop computer.

    So, I shouldn't have an issue doing the update though, when all wiring is completed for the Terminator?

    No, that's how the ECU firmware update is usually accomplished (EFI system completely installed).
