Default FITech fuel injection

Looking at installing their new system. The carb on my M-715 is causing me to go nuts. I don't know much about FI, other than It does everything I want a fuel system to do. The parts used in their system are all GM over the counter" parts if anything breaks down. I think it is a closed loop system, which is what is better from what I have heard. I even saw there is a way to tie it into my timing with my MSD dizzy and ignition system.
Has anyone here used this system?
Has anyone here heard anything about this company?

Never heard of them, and the use of GM components confuses me. Are you talking sensors and injectors? Or like using the factory TBI, as that looks like a new setup.

Closed loop is the ticket. The new self learning TBI systems that are out all use Wide band O2 sensors, which allow for more precise fuel control over the stock O2s from that era that can only figure out rich/lean.

Yes, I understand it is closed loop with the wide band O2 sensor, and yes on the other sensors being of the GM type. It is a TB set up. I don't know for sure but I think they were using Bosch injectors.
On another note, I understand the fuel pumps for the FI need a pusher type pump mounted in or next to the fuel tank. Would the pump be able to handle being next to the tank on the frame rail, pulling the fuel out of the top of the tank, then pushing it forward to the engine? I ask this because the tank is like 15 to 18 inches deep and the bottom of the tank is close to level with the frame rail.

Thanks for your input.

I have one on order for my big block. They are currently on back order with a 2 - 3 week ship date.

I have read a lot of reviews on them and they seem like a pretty nice setup, it is a US branch of a Chinese company, which is how they keep the price so low. I'll be using it on a built big block, and from what others have said, they are all happy with it.

If you plan on using it for timing control as well, you do not need the MSD box, you can use it if you want, but it can provide that function as well. Their customer service has mentioned to me that if your distributor is more than 10 years old, don't expect it to work without having issues, using your MSD you should be all set though. They sell a phasable rotor for their dizzy that is recommended so you can dial everything in perfectly.

There are a LOT of people using this on the mopar forum that I am on, I think it's about a 30 page thread now talking all about it. 98% of it is positive, the 2% that have issues are all timing control related, which seemed like it was incompatible parts.

They also have their fuel command center for fuel. That is what I plan on using, its a sump that you mount where ever you want (usually under the hood) and your stock mechanical pump fills the sump, then it uses an internal high pressure pump to push it to the throttle body. It's not as clean looking as a in tank or near tank pump, but seems much simpler.


And if none of this works with my engine, since I am pulling considerably much less idle vacuum than it requires, I will have it all for sale in a few months.

So, you end up with a small fuel tank under your hood, fed from the main tank by the stock mechanical fuel pump? How large (or small) is this?

Yup, pretty much. The top is 6" in diameter and the bottom is about 3" I think. Its just big enough for a pump and 1 quart of fuel.

Here's the link..

Its not the cheapest, but I compared it to getting an EFI tank with an in tank pump and having to run high pressure lines the length of the car. This ended up being considerably cheaper.

Definitely. I have been looking to put EFI on my 68 Chevy van but gas tanks are hard to come by and expensive- and modifying a 48 year old gas tank does not sound like fun. This would solve all those problems.

That's kind of why I went with it too, so much simpler. And if you get the FITech EFI setup, the fuel command center hooks right to it, so easy hookup. It controls the voltage going to the command center based off of fuel demand, so the pump isn't going full speed all the time.


If you are really bored and have some time, here is the main thread I am following. They don't get into the timing control stuff until about half way through.

I ordered the black version of the 600 horse power one. IF you shop around you can get them cheaper than summit, plus I think it ends this month, but they are offering a $100 rebate. I bought mine from a forum sponsor on a different forum and got almost 10% off as well, it was just over $800 shipped after the rebate.

I think FI Tech is actually a Chinese company trying to tap into the US fuel injection market.

I was researching FI systems last fall and I would suggest taking a look at the new Holley Sniper EFI.

The nice thing about Holley is you can go down to Kentucky and take fuel injection courses. that and they've been around forever.

I run megasquirt. I have a fuel pump that is mounted under the jeep from a ford econoline van. I run the RCI behind the rear seat 15 gallon cell. It pulls fuel fine.

I did read the other posts on the mopar site. Long indeed, sometimes off topic but thats normal.
I think Im ordering mine tomorrow.

I like the last few pages of that thread where people are posting their solutions to problems. It really seems you can tune out just about any issue with it.
I'm hoping mine ships soon, he said 2-3 weeks, it'll be 3 on Thursday.

I went with the FAST ez-efi on my Jeep, Been on there for 4 years now. The first gen had some issues that could be worked through but I heard they fixed it on the 2nd gen. I use a stock electric fuel pump and regulate it but the "self-learning" feature made it really easy for me not knowing anything about fuel injection. Same type of deal with Chevy components on a throttle body.

Only thing I still need to figure out and can't find any solid info on is tweaking the air/fuel ratios for idle, cruise, and wot. But the computer uses preset values that work ok.

Should be fine. I've run an external pump on the frame rail in a few different configurations (old Projection TBI 4Di and factory GM MPFI) without issue. I had the Projection system on my Wagoneer, and didn't have issues. I will say that the nice thing about in tank mounts is that they are quieter.

So are they using modern injectors like in the new multiport setups (50-60psi) or still using older TBI injectors (10-15psi)?
