FiTech Fuel Injection

In the brief research of I've done there has been mainly positive reviews but, also some negative. Just wondering if anyone has any personal experience with the setup or additional thoughts or opinions? Thank you in advance.

When it comes to aftermarket parts there will always be some issues with some applications. Unless all reviews are negative - which they aren't - I wouldn't shy away from using the product. Make sure you get the right unit for your application and follow the instructions and you should at least be in the ballpark. I've "heard" the tech support is a little lacking but now that the product's been on the market a while it should be improving.

My opinion is Throttle body EFI is a waste of time & money.

While my opinion is that throttle body injection, properly set up, is like a perfectly tuned carburetor. As most people are not competent to tune a carb perfectly, these bolt-on TBIs are very much worthwhile.

I have it on my '89 Diplomat with small block stroked 360. I had mechanic install and setup and I'm happy with it. I have better starts now than with carb, which was my main reason for purchasing. I was tired of dealing with difficult idle with cold starts and even some trouble with hot starts. I think throttle response is better too but can't be certain. I may have already squeezed every bit out of the engine. I did have to return the first Fuel Command Center to Summit due to failure of the pump, but had no problems and received a new one quickly and cost free.

these are worthwhile to help you enjoy a car that otherwise would have a less than optimized carb on it. are the be all end all for performance and tuneability? NO. but its a pretty good system. don't waste time with the fuel command center.

But TBI is a fraction of the cost of port injection.

I have a 528 hemi putting out over 700 hp. It runs on pump gas with radical cam 4 speed. I have the fitech 1200 hp on mine. A friend of mine has put several on before with little issues. Mine was a little harder to dial in because of it being so radical. But it is a different world as far as starting cold or warm. It learns your driving habits. As far as tech support they answered all my questions. I had no problem with them. Feel free to ask any questions.

Before purchasing anything, join FiTech owners group on FB. Really get a feeling if it's for you or not, prior to getting involved.

My experience exactly, makes the car just so much more enjoyable to drive.
Just got tired of all the carb related issues. So nice to jump in car and have it start immediately, hot or cold. More responsive, no stumbles.......

A large fraction maybe depending on who's system you go with.

The ONLY slight downfall to TBI IMHO is you are still depending on the manifold and airflow to deliver the fuel.

Port injection gives you the advantage of being able to trim fuel, cylinder to cylinder which unless emissions is your concern is not much of an advantage for the average user.

Only if you have sensors on each exhaust post - adding even more cost to port injection.

TBI is by far the simplest and most economical route to go.

Exactly.

I don't think you shouldn't throw out bold statements like "don't waste time with the fuel command center" without providing reason. I've had no problems with mine other than a bad pump from the get go. Since then I've put many miles on mine in hot Florida and had no problem whatsoever, and it saved me a lot of money and time. Yes, there are pros and cons, but again, just throwing it out there without explanation does not help the o/p.

I installed my unit myself cleanly and as the manufacturer suggested paying attention to the details. New clean tank, 3/8 fuel line, properly returned FCC vent. I've had not issues other than needed a software update

Thank you again everyone. I figure I'd try to get some feedback since I'm potentially considering throwing this onto a Late B-Body like a near stock 318 or 360 small block.

I just got mine running this week. It does start up quick. Have not put any real miles as I rebuilt my front end and need an alignment.

I went with an in tank Aeromotive pump.

Actually no. Computers and O2 sensors are fast enough now that with engine position sensors the ECM can tell which exhaust pulse comes from which cylinder by monitoring the O2 sensor data.

That's how the ECM in new cars can throw a code to tell you which cylinder is misfiring.

My friend has a big block chevell that ran a Kinser toilet running on alcohol , 14 :1 compression .The car ran 8.70 at 150+ mph. So, he decides to buy the FITech 1200 HP set up. He don't know squat about electronic stuff but he installed it. Surprising to me now the car starts right up, idles like a stock engine, still radical but has instant throttle response and still running alcohol. The FITech did slow the car down .3 He says it is because the FITech doesn't flow as much as CFM as the toilet did. Now I must say this car repeats every run down to the thousants, 60 ft. , 1/8 and 1/4 mile. He's even going rounds . Whats with that? I should have bought the FITech instead of the Holley dominator. I can see one in my future.

I have to disagree, way simpler installation than frame-mounted pumps or for cars where in-tank pumps aren't practical. Mine has given me zero problems.

I would look into the Holly Sniper system before making a final call on FiTech.

That Fuel Command system would be cool in a Moon tank mounted in the grill for that gasser look.

When someone makes a statement like this with no reason I don't waste my time with it.

there are lots of documented cases of the fuel command center failing. mine was one of them. I did try it. ended going with a tank mounted pump. don't know why it failed maybe not enough fuel flow? needs a real return back to the tank to circulate fuel so it won't over heat.

if you are going to try it. make sure you attach the vent line to a fuel return line back to the tank. plenty have tried not to, only to have fuel shooting out of it. its almost as if the float fails.

Without a comparison of failure rates of other fuel delivery systems, anecdotal experience is just that.

Don't need that.

All you need is data on the command center failures.

MTBF is solely calculated on the unit in question, not some other system.

Mine is located in same spot, and that's the key, properly installed return line!

Well a little update on the FITech set up my buddy has. It seems that he doesn't like running 9 flat so he picked up the new Holley Sniper fabricated sheet metal intake for his big block. This set up is for 2-4"s. He says that another 1200 FITech will be just right. I looked at a number of those intakes, LS, Big blocks, Small block and for Fords. No mopar as of yet but they sure are light and look mighty fine. To be continued.

Thank you everyone. Looks FITech makes a kit for Summit too. I've read that part of the FCC failures is due in part to the fuel pump? I've read guys replacing the unit and pump. Anyways, I'll keep my eyes out and continue to see how things play out with these units.

Without changing the default settings, the pump in the FCC runs at full pressure throughout the operating range which might account for the reported failures. The pump can be slowed at idle with the hand-held controller.

Yes, this is what I read in FiTech's solution to problem and set my per. I did still have a bad pump from the get go because mechanic commented at install he didn't like how it seemed to be flooding at beginning.But as I said, all good now and I'm happy with it since and the easier starts and improved cold idle alone make it worth it to me.
