Thread: Upgrading EFI

  1. #1

    Default Upgrading EFI

    I have an older Terminator 550-405 with the original handheld that stopped working. I have a 3.5" TSLCD handheld. However, I receive a message the EFI firmware needs to be upgraded.
    Can anyone recommend the specific version I need and the process for upgrading the firmware? Thanks.

    Which version is your Terminator ECU now?

    EFI Software & ECU Firmware Versions:
    EFI SOFTWARE: Click "Help" tab (top toolbar) & "About Holley EFI".
    ECU FIRMWARE: Click "Sync With ECU" & "Get ECU Info" (Key-on/USB connected).
    The latest EFI software & ECU firmware can be downloaded here:
    https://www.holley.com/support/resou...Fuel_Injection (Holley EFI Technical Library)
    http://documents.holley.com/techlibr...rmwarerev1.pdf (How To Update ECU Firmware)
    Before updating firmware, ensure the current Global File is saved somewhere, since it will be erased from the ECU.
    May God's grace bless you in the Lord Jesus Christ.

    The ECU firmware is V2. It seems your 3.5" TSLCD is V4. Yes, mismatched firmware. The ECU needs to be outdated anyway. I'd just update everything to V5 EFI software/ECU firmware. The EFI (laptop/PC) software, ECU firmware & touchscreen unit must all be version compatible (LINK).

    OK thanks. So then which file in the library is the correct set? Holley EFI V5 Build 170 complete file set?

    Yes, for the regular Terminator, not Terminator X.

    Hi. I have the same problenm old Terminator ECU FW 0.0.587 Device FW 4.0.200. You say before updating firmware, ensure that the current Global File is saved somewhere. How do I do that? Can't read my old handheld. Regards, Thomas

    Yes, you can save your Global File onto a USB flash drive or an SD card. It's in the Terminator X instruction manual.
    I wouldn't save it in the Holley HEFI folder (in Documents) because the software update modifies that Holley HEFI
    folder. Save it on the Desktop screen or in your email. (I always keep a recent copy of my Global File in my email.)

    The 3.5" TSLCD & Digital Dash can retrieve your Global File from the ECU.
