FiTech EFI system

-
Has anyone got to the track with is setup. I would like to know more about how it performs in a real-world situations. I know everybody wants to know how they install and all that jazz but I want to know more about the performance end of it. :burnout:

Sorry, I don't take my car on the track so can't help you out. Will add that it has great power as far as I want to push the pedal... Smoothest it has ever run at higher speeds.

I have cleaned up the underhood wiring now that i am comfortable the ecu is controlling the timing well.. real well actually.. and just need more time behind the wheel.

Trying to get it to the track but i got another car to fix ahead of it......
 
A good carb properly tuned for the track will outperform the EFI, or at the very least you won't notice a difference converting over. The benefit is in the driving to and from the track. Smoother idle, a little better gas mileage, less fuel wash, crisper part-throttle response. I'm converting the Coronet because I plan on driving the s#@t out of it once it's done.

Not to mention not having to worry about how many times to pump the gas depending on the outside temp, dealing with a choke, and all the other stuff that makes a carb a PITA for a car that gets driven regularly.
 
I'm going with one of these EFI setups this winter. My car is a daily driver all summer. And adding efi should add a good 2 months of driving. And help with the fact that a canadian spring/fall day can start at 10C or lower and end at 30C. Which can be difficult for a carb. The ability to get in and go at any temp is premo.

Performance carbs are called off-road cause you're always off the road adjusting them. I would run a carb in a weekend cruiser or track car, but in my daily driver I want to drive as much and often as I can. And EFI affords me that without constantly playing with it.
 
I have bought the 8 injector unit and am currently trying to work out what the optimal ignition setup would be if I wanted the go-efi unit to control ignition too.

Was hoping not to have to buy completely different parts down the track if I choose poorly now.

My plan was to add boost (88mm garrett) once it was all going, 7-10psi at most using e85. Power goals are modest (in my opinion) at 600hp, if it goes more, even better.

If I don't get at least a basic CDI unit, will I need to run a ballast type mopar ignition setup? HEI seems a no-go if I use the fitech for timing. So, with my knowledge of car mechanicals being 2/10ths of jack ****...what sort of ignition setup do I "want" for my purposes?

PS. Please excuse my ignorance.
 
I received my throttle body package this morning - everything really looks great. The fuel command center I ordered is back ordered :banghead: Am going to either monkey around with adapters so I can use the original temp sensor and the larger temp sensor they provide (which is probably going to look hokey) or use 74 slant head I have which has both sizes :cheers: Of course then I need to get the head freshened up #-o
 
the TBI showed up a couple of days after ordering. The FCC is going to be a few weeks out. Meanwhile I drilled a hole in the header collector/reducer for the AF sensor; welding the bung this weekend.

ok. O:)
 
Whats the consensus on the Fuel Command Center fuel pump.

My son is willing to hook me up with a NEW tanks inc setup with an in tank pump for fuel injection.

Should we save the bucks and get the one from FI tech?
 
My fuel command center is still back ordered. It looks like it's matched with the injection unit with no tank mods or running return lines to the tank. Simplicity is what I like about it - now I just need mine!
 
I have been driving mine sporadically for the last couple of weeks. With the system controlling timing, I was getting some exhaust backfiring on deceleration. After consulting with Fitech, I went back to using Distributor and vacuum advance, and using the system for fuel delivery only. The decel backfire is gone, so I must have had something wrong with the locked distributor setup.
I think for rest of the season, until it snows, I will leave the ignition duties to the distributor and play more with computer controlled timing in the spring.

I did wind up putting a new alternator on because in idle with the headlights on, my voltage was running close to 11 volts.

It's starting to get cooler up here in the mornings already, but the car starts and idles nicely. I can put it right into gear with no stalling, no feathering of the throttle.

I am currently altering the settings for the accel function as I occasionally was getting a backfire/POP thru the throttle body on mild to heavy gas pedal movement. It is much better now that I enriched it. Fitech says it would be a lean condition causing that issue.

Unfortunately I have not done a lot of driving, the system is still making changes to it's settings( learning) as i drive.

No more stinky gas smell, and very smooth under acceleration and higher speeds.

For a mile street car, it's great being able to change settings without taking a carb apart.

Hope that helps!!
 
^ Thanks for the update. I'm still on the fence as I currently have no induction system and am deciding if it worth the $1300+ to make the jump on a Sunday/occasional driver.

I went with the tanks inc in tank pump thinking it would be cheaper. I'll tell you it is not cheaper! Tanks pump $296.00 Russell braided line from Pep Boys for delivery and return lines. $216. Various AN-6 fittings and filter $130. I could have nearly bought 2 command centers and saved hours of work.
 
So anyone who's got theirs up and running have an update?

I got mine installed. Once I set timing it ran very well. Ken is the man at FI tech! I was having an issue with it being hard to start. Had to adjust the idle screw a 1/2 turn to open the blades a little. It was choking the engine. If I open the throttle with the peddle it would start right up. The more times you attempt to start it, turn the key off and try again it delivers another shot of fuel adding to the rich fuel mixture already there, combine that with throttle blades closed off and you get an engine that is hard to start. Just a few minutes with Ken on the phone and he had it starting and running like a champ. I took it for its first drive. I was smiling from ear to ear.
 
Anyone have any pictures of the fuel commander thing installed in an engine bay?
 
i will get you a couple of pictures tomorrow...mine is in the front near the radiator support but bolted to the fender...
 
Explain this please. I don't understand how if they both flow what the engine needs how a more primitive one is superior to the more advanced one?

Because at wide open throttle the air velocity is so great that even with a carb the fuel is atomized very well. The big advantage to and EFI setup is not wide open power, it's good fuel atomization at low to medium engine speeds which relates to smoother idle and better all around driveability as well as an improvement in fuel mileage and less emissions

Thanks for those pics. That is exactly where/how I had planned to mount mine. Nice to see it will work as planned.
