We got a little carried away with the discussion and the primary topic of that discussion was already underway over here. All of your posts were moved to this thread : FI Tech and in tank fuel options

Quick update. Well, nothing really. Got email yesterday from JEGS that the back order of the fuel commander was pushed out another two months to early December.

Will see if I can track one down somewhere else, otherwise, won't be installing for a couple months at least.

Sounds like they are having troubles sorting out the problems they are having with the fuel command center. Have you considered using the Edelbrock one? Looks like 3605 would be an exact spec replacement for FiTech's. If you wanted more fuel volume then maybe the 36033 would be a better choice.

I cancelled my command center order after talking to them - between the massive back order and the fact they said the command center is not good for off roading. I am now going in tank using 89 pick up, stealth pump & AN all the way to the throttle body & back. Will cost ~$150 more than the command center when all said and done, but will look killer.

i think that is a good idea anyway. You will be much happier with an in-tank solution.

Definitely following progress on this. I'd love to start an engine build in the future and put this style of EFI on- keep it coming! Looking forward to seeing your progress now that you're bypassing the out of stock problems.

Well, I'm still willing to wait for the fuel commander. I did look at the Edelbrock one (someone mentioned it awhile back), but like the fi tech one better.

Any updates on this?

I have a specific question. I'm looking at the Holley Sniper system but I believe my question will apply to the FiTech system as well.

The ECU in the Holley setup requires a switched +12v power supply while in the Run & Start key positions. What keyed power supply (which wires) will you be tapping into, to supply the power in the Run & Start positions?

If I interpret my wiring manual correctly, there is no single wire that is powered in both Run & Start. What I believe this means, is that I will need to tap into BOTH a hot Run wire and a hot Start wire (2 separate wires) and use a relay to switch between the two.

What do you think?

Stuff is sitting in my shop. Just dealing with life and waiting for better weather.

As for the question, I've not actually looked yet. Was going to look at wiring diagrams when I got ready to install. But I think a good place to start is the solenoid. I maybe remembering my old cars wrong, but I think there is a wire/post there that is hot in both run and start.

Let me know what you find, I'll need to know later as well. :)

Did you end up finally getting the fuel command center?

I found with my FCC, that plumbing it like the directions say, that it works great. I first plumbed the FCC vent to the ground, but it was pissing fuel out the vent. Plumbed it into the vapor line and it works great. My 78 Bronco is a CA model so it has the return line and vented cap. I hope this takes a little of the anxiety out of "will the command center work on MY vehicle?"

Is there a great disadvantage in not having the timing control? Will it still be good for cold weather starts?
Hossrod, what dizzy are you using for your install?

I don't think it's a great disadvantage. Although I do plan on enabling it later. You still have the normal vacuum advance curve.

I don't know what dizzy it has in it, but it looks like a cheap OEM reman one. I think it will be fine cold starting. Of course haven't tried. But it should be better than carb.

Just installed new DUI distributor a month ago and it's running pretty good. Then last week I got the Fitech 400 kit, and after researching the wiring connections, it seems that the Duraspark-2 system won't work because it has a ballast resistor.

From Fitech FAQ page:

I have a 1972 Ford 302 with a ford dura spark ignition. Will this ignition system work with the your EFI?

The system will work with digital 12 volt ignition. If your ignition has a ballast resistor it will NOT work.

So now I have to figure out if I want to get another new distributor, or see if I can return the Fitech system to summit.
Or is there any way to remove the ballast resistor and not damage the ignition system.

Any suggestions welcome.

I have a DUI dizzy as well and I just completed my FiTech install and it all works fine together. I also run an MSD blaster coil and an MSD 6AL box. My tach wire for the FiTech is connected to the Tach Out on the MSD box.

So you use the MSD box in place of the Duraspark box and wire it as a conventional 2 wire distributor.

To the guys that have their system hooked up, where did you hook the white wire to, the one that needs to be hooked up to the CPU. It has to be hooked to a wire that is hot when cranking and in run position. I don't want to fry anything wiring to the wrong place

Thanks,
Marty
