    Updating Terminator Stealth Firmware

    Hello. I have an older Terminator Stealth EFI that I purchased several years ago. I have it installed along with a Dual Sync distributor and an MSD 6AL CDI box and standard coil. The firmware version on my ECU is 4.0.64. There's no option for running the Dual Sync distributor.

    I phoned Holley Tech support and was told to download Version 5 from the HP/Dominator section. I took a look at the description for Version 5 and saw nothing about ignition upgrade options. Is this what I need to do? Thanks in advance. Joe

    FYI: Holley EFI now sells their own Dual Sync (LINK) & HyperSpark (LINK) Hall-Effect distributors.
    They're a small cap design, "plug & play" with Holley EFI, and no need for a modified Firing Order.
    The Dual Sync crank & cam sensor signals also provide sequential injection capability (MPFI applications).
    The Dual Sync is "plug & play" (into the 10-pin ignition connector on the EFI Main Harness), and both
    distributors require a CD ignition box (Instructions), unless the Dual Sync is used with a CNP ignition system.
    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:

    https://www.youtube.com/watch?v=2JpHlS1ymBc (Holley EFI HyperSpark Distributor - YouTube Tech Video)
    A Dual Sync blank cap is available, if the user decides to convert to Coil-Near-Plug/DIS later (no CDI box).
    Of course, the Dual Sync distributor 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" (← Holley Dual Sync Distributor)
    Sensor Type .............. ― "Digital Falling"
    Inductive Delay .......... ― "100.0 usec" (← Synchronization info, adjusted per application.)
    Ignition Reference Angle ― "50°" (← Inherent Ignition Reference Angle & 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 Fixed Duty Cycle (MSD)" (← MSD CD Ignition Box)
    -----------------------------------------------------------
    Holley CNP Smart Coils and/or GM LSx Ignition Coils (no CD ignition box required):
    Output Setup Type ..... ― "DIS Coil On Plug" (← Holley CNP Smart Coils and/or LSx Ignition Coils)
    Dwell Time ................ ― "3.5-5.0 msec" (← See page 1 for Holley CNP coils, and page 3 for GM LSx coils.)

    The Custom Ignition Parameters (in System Parameters) for the Holley EFI HyperSpark Distributor:
    Ignition Type ............. ― "Custom"
    Crank Sensor Type ..... ― "1 Pulse/Fire" (← Holley HyperSpark Distributor)
    Sensor Type .............. ― "Digital Rising" (← I prefer Digital Falling, LINK.)
    Inductive Delay .......... ― "100.0 usec" (← Synchronization info, adjusted per application.)
    Ignition Reference Angle ― "57.5°" (← Inherent Ignition Reference Angle & rotor-phasing of this unit.)
    Cam Sensor Type ........ ― "Not Used" (← This distributor doesn't have a cam sensor.)
    Output Setup Type ..... ― "Points Output Fixed Duty Cycle (MSD)" (← MSD CD Ignition Box)

    The 10-pin Ignition Connector has one "Chassis Ground" (loose black wire ground) and two "IPU Grounds" (clean ECU ground).
    Don't use "Chassis Ground" to ground an ignition module (or crank & cam sensors). It's quick & easy to move the ignition
    module ground wire from (cavity) pin D "Chassis Ground" to pin C or G "IPU Ground", where it should be.

    If you don't have the actual Metri-Pack terminal release tool, a "safety pin" will work.
    It just needs to be a stiff wire between .030"-.035" in diameter to release the terminal tab.
    Then reopen (bend) the terminal tab before reinsertion, so it will clip (lock) into the cavity.
    http://www.whiteproducts.com/removal_tools.shtml (T-6 Micro Terminal Release Pick Tool)

    Also, don't use (cavity) pin E "Switched +12V" from the 10-pin Ignition Connector, to power an ignition module
    (or crank & cam sensors), unless you've modified the wiring source to connect from pin B20 - EST 12V Output
    (P1B ECU Connector). This LINK explains why & how to do it.

      Danny, Thanks for replying. so do I need to load version 5 and not 6? The files are found at the HP/ Dominator section? There seem to be more than three files in that section, can you specify which files need to be loaded?

      My goal is to load the files needed onto a new 8 gig SD card, then load that card into he 3.5" handheld, since I don’t have a laptop. My son said he can help with the file transfer to the new card, since he is far more computer savvy than I. I hope that it’s as straightforward as is seems. Joe

          Thanks Danny. I’m a bit confused about all that info and if it all pertains to me. I hope it will be a bit clearer once I get started,

          As for what file(s) to upload to my new SD card, is it just the highlighted one or is it multiple? The Holley tech said three files that needed to be in zipped. There are more than three files here. Joe

            The V5 Build 171 Complete File Set is what you need. The EFI (laptop/PC) software, ECU firmware & touchscreen unit must all be version compatible (LINK)​
