Thread: Setup & Component Help

    Default Setup & Component Help

    '93 Ford Fox body, supercharged. I'm currently at 500 RWHP will be going to 700-1000 RWHP after my Dart block is built. May upgrade the supercharger or possibly go with twins. I'm thinking Coil-On-Plug or Coil-Near-Plug would be a good feature to add. I want to ditch the stock IAC for something better and cleaner. I'm leaning towards the HP, but open to suggestions. Car is a Pro-Touring street/show build. Also wondering if it's possible to integrate a push button start that uses a key fob like a new system instead of the keys. Thank you.

    If using Holley's 556-112 CNP coils, the Holley 558-318 CNP coil sub-harness is also required (or the Holley 556-128 CNP Big Wire V8 Kit).
    For LSx coils, Holley 558-307 CNP main harness plugs into two GM 12579355 CNP sub-harnesses or Holley 558-321 LSx coil sub-harnesses.
    If you had a Holley EFI LSx main harness, you wouldn't need the Holley 558-307 CNP main harness or the 558-318 CNP coil sub-harness.

    With the Dominator EFI, everything is sold separately. Use Summit Racing's shopping cart for a total price.
    The HP ECU only has four Inputs & four Outputs. If you need more than that, you'll need the Dominator ECU:

    Ensure the EFI software is set to run as an "Administrator" (right click for Properties/Advanced). Set it and forget it.

    I suggest the Holley Dominator EFI for the extra I/O and dual WBO2 sensor capability.

    Thank you for the insight. Do you prefer the smart coils over the LSx coils?

    Yes, especially at your new power level.

    So if I go Dominator EFI, what main harness would I need? 558-105? And I see MSD offers crank triggers and cam sensors as does Holley. I'm completely new to stand-alone systems. I rewired my whole Fox body a couple years ago so I can do electrical per se, and have all the tools for making proper connections. I'm just not sure what I'll need as a whole "package" since they don't offer Fox specific ones (besides the Terminator X). I have purchased nothing thus far so I'd need everything. Trying to make this build as reliable and clean/modern as I can. Thanks again for your help.

    That depends on if you've decided on Coil-Near-Plug ignition system. If so, this main harness integrates the CNP harness into it:

    Holley EFI 556-115 36-1 Crank Trigger Kit (more resolution than MSD 4x Flying Magnet) and an MSD 85221 cam sync unit.
