Thread: Stealth Ram Distributor Wiring

  1. #1

    Default Stealth Ram Distributor Wiring

    I have a Joe Hunt electronic distributor and would like to know how to connect it to the ECU.
    I only have a tach wire that leaves the distributor. Everything else is internal in the case.

    There are three types of distributors listed for the setup. Which one will I select?
    Thanks, Allen

    Is this a magneto distributor? Is there an ignition module inside the distributor?
    Is there a CD ignition box? I assume this won't be a computer controlled timing application?

    • RPM input signal: If you're not controlling timing, and not using a CD ignition box, use the loose yellow wire from the main harness.
    http://documents.holley.com/techlibr...10555rev17.pdf (Holley EFI Wiring Manual, Page 16)
    In the EFI software (Ignition Parameters), select "Coil (Inductive Coil Only, No Timing Control)" Ignition Type.

    • RPM input signal: If you're not controlling timing, with a CD ignition box, use the yellow/black wire from the 10-pin ignition adapter.
    http://documents.holley.com/techlibr...10555rev17.pdf (Holley EFI Wiring Manual, Page 17)
    In the EFI software (Ignition Parameters), select "CD Box Tach Output or any 12V Square Wave (No Timing Control)" Ignition Type.

    If your kit contains a 558-304 ignition adapter harness (small cap GM HEI distributor), it can still be
    utilized by cutting off the small connector, and wire your distributor type according to the wiring diagrams.
    This is outlined in the Holley EFI Wiring Manual (center of page 15), and avoids cutting into the main wire harness.

    • ECU controlled timing: Look at the wiring diagrams in the Holley EFI Wiring Manual, beginning on page 13.
    http://documents.holley.com/techlibr...10555rev17.pdf (Holley EFI Wiring Manual, pages 13-21)
    In the EFI software (Ignition Parameters), select the appropriate Ignition Type of ECU controlled timing.

    Additional ECU controlled timing steps, read tech link below:

    If timing is not ECU controlled, there's obviously no synchronization.
    Simply install the distributor as you would on a carbureted application.

    This is not a magneto. All I can see is a rotor with the cap off. I assume there is an ignition module inside the distributor. There is no CD ignition box. This will not be computer controlled timing. I see that by answering your question, I also answered mine, but just wanted to be sure! Thanks, Allen

    Everything is in the base of the Joe Hunt setup. I have one that is similar except custom made by Joe Hunt to be a dual sync setup for sequential injection.

    Thanks. That's good to know, for those who need a custom dual sync distributor that's not available from the aftermarket. But does this custom dual sync distributor simulate a magneto unit?

    It only looks like a mag! Inside there is a ignition coil in the very bottom and two sensors in the top for cam and crank sync. I'll take a pic sometime if you want.

    Yeah, that's what I thought. Personally, I wouldn't want that look.

    You don't have to trouble yourself, I understand the concept.

    Yep, that's why I don't use it anymore. At one time I ran a Hilborn EFI setup and used it for a period correct look. Ran good, just eventually made a engine change. Tom
