Holley Performance Products Terminator EFI

[Derekk]

Man I would really like to try that on my 454! Hope to buy one before rtth. Can it be run with the push lock fittings or will the 45# be to much pressure? I have 1/2 line now with a holley mechanical pump and holley billet regulator. Wish I could use those to save some money. Looks like a great product, I've always loved holley's.

If you are running Earl's Super Stock hose, the push lok fittings will work fine. If you are using some other brand, you will need to check with that manufacturer.

Just installed Holley Terminator EFI on my 69 Mach 418W, I am very pleased with the results. Using Ford TFI to control the timing, pieced together the fuel system using an Aeromotive 18697 tank and PTFE fuel line. I have had to do nothing but drive the car. Write the check, EFI is worth every penny.

Nice looking ride. Glad you are a satisfied customer

derek looking to put it on a zz454, should be good

[Derekk]

Nice. Post some pics as you go along.

What are the number-letters cast on the center exhaust ports.

Its a 73' 455, .030 over, cast piston, cast rod, performer intake and its got 6X-4 heads on it

Anyone got Terminator EFI installed . POST Pic's

hifi875 has it on his Camaro.

How does it control the fuel pump? Does it just turn the pump "on" with the key on or will it prime the lines and run the pump only while the engine is running? Can it be used return less? If it needs a return line can it be used with some sort of a fuel pump speed controller, like the one made by Aeromotive? (I'm thinking of using one of the Aeromotive drop in tanks).

[Derek@ModernSpeed]

The pump will come on for a 5 second "prime" cycle, shut off, then come back on as the ecu picks up the rpm signal. The system cannot be used with a returnless fuel system, you can use a pump controller if you like, however you may end up keeping the fuel pump independent of the ecu control. The ecu outputs a solid 12v signal. You might be better off allowing the ecu to send 12v to a secondary relay, which provides the 12V to the controller.

Ok. Do you think that the Aeromotive "Stealth" pump (340 liters/hour) looks like a good fit with the Terminator? I want an in tank pump that flows enough to supply the motor but not too much so that it overheats the fuel and itself. Thats why I was thinking a fuel pump controller. I really don't want to overcomplicate things if I don't have to though. I'd rather not use one if its not needed. I like the way the ecu primes and then turns on with a rpm signal - will it turn off the pump if it looses the rpm signal? Also how much fuel pressure does the Terminator efi run at?

[Derek@ModernSpeed]

I think the 340 lph pump without a controller will be fine. The system runs at 43 psi. The pump, and ignition will shut down when the ecu loses the rpm signal.

Ok. So far your system really stands out. Before this thread I was leaning toward the MSD or FAST, but I really like the upgradeability of your system, and the OEM sort of way that you run the pump is great too. One other thing that I can't seem to find much info on with your system though is ignition timing. What kind of ignitions does your system support? I have a very simple "billet" distributor that runs off of a MSD digital 6 box. So the distributor only controls mechanical advance, actual spark distribution to the motor, and provides a reference signal to the MSD. Having timing control is nice, but not really a deal breaker for me. Would your system be able to control my timing?

[Derek@ModernSpeed]

Yes, the Holley can control the timing. You can actually use the magnetic distributor you have. Lock the rotor, wire the distributor up as a crank trigger, and sync the timing with the ecu. Pretty simple/standard setup. You will continue to use the MSD 6 box to energize the coil in this application. Let me know if you need pricing.

[another69]

Give me pricing if you can. I am planning on using an Aeromotive tank and would be more than happy to give you any other info that you need.

Hi Guys,

Looking for some information on what I need. I have a Dominator ECU, I need to order the harnesses, can you please let me know which ones.

I have a 440 RHS block with mast motor sport heads, Ozmo dual throtle body setup with fly by wire. I have the recomended GM throtle body's and pedal assembly. We are going to run it on E85 with 2 x ZL1 fuel pumps and the vaporworx controller.

Thanks in advance
Greg

Hey Derek,
I'm installing the holley fuel system for an LS1 with the 550-602 ECU & Harness. Did all the wiring but can't seem to find a wire for the electric cooling fans, though there is a hookup for temp. Also can't figure which wire to use for the factory tach, though there is a yellow wire for RPM out (do not use on CD coil). Is this the wire to use for tach?

Greg - John510 in Lat-G has looked into this and may be able to help.

Thanks Ron.
