Fitech fuel injection gurus - 06/29/20 09:52 PM

I know a guy that has a new never used Fitech 30005 600hp set up
I can get it for $400 I know I need fuel pump set up for this
is this a good set up or are there better ones out there???
I know price wise its half priced
I have a 413 with dual quads afb's on my 69 D200
what do I need to put 2 on my 69 besides the obvious one more Fitech.
I am not a computor wiz at all
thanks for any info

The dual quad part won't work. If you want to run that Fitech throttle body then you'll need to buy a new single 4bbl intake. If you want dual quad EFI then you need to buy a dual quad EFI kit.

Besides the fuel pump, you will need a fuel regulator, baffled fuel tank, return line, and all the higher pressure fuel line. I think they like to run with 51-53 psi. For specifics on running 2 units, email them directly or call with the questions you have. They may be a bit slow getting back to you but they had always returned answers to my questions. There is a lot of info on forabodiesonly.com as well.

OK I have a dual plane single 4 intake I can put it on
is this system easy to set up? for a first timer
or should I run away as fast as I can
is it a good buy at that price or not worth the trouble?
thanks

I wouldn't recommend it unless you have someone who can help you with the install. Non computer guys have trouble installing EFI. You need to know how to use google to search for information, search youtube for videos, attach files to email, move files from drive to drive and things like that. If you don't know how to do those things then you'll need someone who can help you get it installed and working.

All the guys I’ve know that have installed the fiTech have had some type of trouble. Some have given up and gone back to carbs. The Holley system seams to be the preferred one.

I have a Fitech, on a 410 LA engine with a procharger, had a few learning issues, but it works very well after I got the bugs out.
Someone mentioned over 50 psi fuel pressure, nope, mine did not like it at all, it is more like 40 psi. And the unit has a pressure regulator built into it, but it does not have the capacity to control a large volume and pressure fuel pump. All the sensors and replaceable parts in the Fitech are over the counter available parts at any parts store. The pressure regulator is from a 1.8 Volkswagen system. If you have to much fuel pressure, the drivers in the ECU will get hot and shut down. The higher the fuel pressure the more amperage it takes to lift the injector off it's seat. Took me a while to figure that one out. Second issue I had was the Fitech control of ignition timing, use a MSD distributor, I tried a cheap Ebay MSD copy and it ran the engine just fine on a carb, but would not handle the Fitech. Both distributors use a magnetic pickup, but believe it or not the MSD copy makes more voltage than the real MSD and the Fitech did not like it over about 4,000 rpm. Got scope patterns to prove it. Others may have had better luck with other types of distributors, but that was my experience.

Fitech also sometimes has EMI issues. I simply used some of the cheap fake wire braid sleeves to slide over the harness, and that fixed that. Nice thing is it will set a code if that is the problem. https://www.amazon.com/Universal-Stainless-Steel-Braided-Dress-Up/dp/B01MYYHDCF Just solder a ground wire to the sleeve and ground.

The handheld unit that comes with the Fitech is like a scan tool, it even records OBD style trouble codes, just like a modern car. A very powerful tool. My only trouble was with Fitech giving me good info on the parameters that set those codes. I just think the Tech guys on the phone were not trained well in the system. For example when I wanted to send scope patterns for them to evaluate, and or asked for what voltage values certain components worked with to use a scope, they really did not understand what I was talking about. Often they relayed my requests to an engineer, and I never really got a good answer. I will have to say many times I get similar issues with most companies technical phone contacts.

Holley is not immune to this either.

From what I understand, one of the TB's in their dual quad setup is just a slave so the single could be used with the addition of a slave. Contact FI Tech.
