Thread: Dual Sync With Terminator?

  1. Default Dual Sync With Terminator?

    Forgive me if this has already been answered, but being at work I cannot take a lot of time to do research. My question is this: Can the Holley dual sync distributor be used with the Holley Terminator EFI to control ignition timing? I'm currently using the Ford TFI setup, and already hate it due to the unreliability. Any help would be greatly appreciated. FAST or Holley dual sync?

    FAST or Holley dual sync?
    Why would you not use the Holley Dual Sync distributor (with two Hall-Effect sensors) that's specifically designed and "plug & play" for Holley EFI?

    FYI: Holley EFI now sells their own Dual Sync Hall-Effect distributors (LINK).
    They're a small cap design, "plug & play" with Holley EFI, and no need for a modified Firing Order.
    The crank & cam sensor signals also provide sequential injection capability (MPFI applications).
    It's "plug & play" (into the 10-pin ignition connector on the EFI Main Harness) and requires a CD
    ignition box (Instructions). The MSD 6201 Digital 6A CDI box & 8253 HVC-2 coil are a great match.
    The MSD CD ignition box is wired as shown in the Holley EFI Wiring Manual:
    http://documents.holley.com/techlibr...10555rev17.pdf (Holley EFI Wiring Manual - Figure 11, Page 20)
    https://www.youtube.com/watch?v=AM7r-DauCak (Holley EFI Dual Sync Distributor - YouTube Tech Video)
    A blank cap (LINK) is available, if the user decides to convert to Coil-Near-Plug/DIS later (no CDI box).
    Of course, this component can also be used as a crank and/or cam sync/oil pump drive unit.

    The Custom Ignition Parameters (in System Parameters) for the Holley EFI Dual Sync Distributor:
    Ignition Type ............. ― "Custom"
    Crank Sensor Type ..... ― "1 Pulse/Fire"
    Sensor Type .............. ― "Digital Falling"
    Inductive Delay .......... ― "100.0 usec" ( Synchronization info, adjusted per application.)
    Ignition Reference Angle ― "50°" ( Inherent rotor-phasing of this unit.)
    Cam Sensor Type ........ ― "Single Pulse" ( "Not Used" for TBI, unless CNP ignition.)
    Sensor Type .............. ― "Digital Falling"
    Output Setup Type ..... ― "Points Output" ( CDI box ground trigger.)
    Dwell Time ................. ― "2.0 msec" ( Do not set this to 1.5 msec!)

    Thank you. I will browse over that link after work. I would prefer Holley, but I heard talk of the FAST. So I figured I would just ask, in case there was a reason for people bringing it up.

    That's because the Holley dual sync distributor is fairly new. (The FAST dual sync distributor used to be their only option.)

    Well that makes sense. How does the Holley stand up to engine bay temperatures?

    Better than most other distributors, because there isn't an ignition module to overheat & fail.

    That is most reassuring. Thanks for all your help Dan.
