Thread: Miserable experience upgrading firmware.

  1. #1

    Default Miserable experience upgrading firmware.

    As per instructions, went to the website to upgrade the firmware for the Sniper EFI. Downloaded it, moved it to the SD card. Replaced into the screen, turned on ignition. Nothing. No matter what I do, the 3.5" touchscreen keeps saying that the ECU is incompatible with the firmware (or maybe the other way around). Anybody have any experience with this? How in the world can I get over this roadblock? Thanks for any help.

    ECU serial number: 00000001
    Date code 20160317
    ECU firmware version 1.0.90
    Profile number :1

    Holley does not have firmware upgrade for the Sniper, but they do have it for the other ECUs. Clear you SD card and download this and it will work: http://documents.holley.com/techlibr...rdcontents.zip PS: Do you have the first Sniper ECU Holley ever made?
