    Default 534-55 Pro-Jection ECU

    Hi there. Holley discontinued this 534-55 ECU. I try to buy new or used or rebuild no luck. Do you have any sources where to find one? Or know somebody who can fix it, or share a PDF with the electronics inside that box? I ordered the new Sniper, but delivery is September 30, maybe. Thank you.

    If you find one, it will probably be used, and I wouldn't trust it (since it's such an antiquated EFI system).

    That's not happening, but you can disassemble it and look inside for any obvious failure.
    May God's grace bless you in the Lord Jesus Christ.

    Thanks Danny, I guess I'll wait for the new Sniper. Not enough time to investigate, plus no electronic diagram, I'll be lost in there. All the best. Alex
