FiTech efi

Mike67 said:
Looks great & impressive! Ive been researching the fitech/fast/ msd just to compare so if the day ever comes I decide to go that way... I kind of like the fcc, but like others have said here it is kids scary having a gallon of fuel under the hood... But I wanted to ask you are the fccs insulated in anyway? Seems to me that would beneficial since its under the hood....or even if it was double walled....
Awesome job thanks for all of the updates!

I'm not sure how insulated the FCC is.
One thing I must add: the FCC doesn't require a filter from the mechanical pump. I've been having some minor tuning issues so I re-read the instructions. I even had the passage highlighted and still installed a filter. :BangHead: Removed the filter today and inserted a 5/16" to 3/8" barbed adapter.
Engine hasn't been idling right - lots of flat spots. Tonight I found the #2 spark plug wire laying on the header. :BangHead::BangHead: After routing away the idle smoothed out. I think ignition issues affect the EFI much more than carbureted. The O2 sensor was probably going crazy trying to account for raw fuel dumping into the collector.
 
Actually the instructions do say a user installed carburetor-style filter between the mechanical pump and fcc is required. It's the 3rd paragraph on the second page of the fcc instructions manual. I have a filter pre-mechanical fuel pump and post-mechanical pump. I am questioning myself on the use of pre and post pump filters. I'll ask Fitech that question today when I call about another question: the direction of flow for the efi-style filter. I don't have an arrow on my housing so I want to be sure which end is in/out.
 
As soon as I seen this unit working great on the autocross...never thought twice about getting one based on the price and true plug and play...nobody has to sit with a laptop as you drive around...really bad experiences before with so called "plug and play"

on a side note I decided to go with a EFI gas tank rather then the command center

I talked to an FiTech tech today. The FCC and throttle body install instructions contradict each other. But the answer is YES, a pre-FCC filter is required. I knew there was a reason I originally installed one. So, the filter goes back on this week.

Thanks for the update! I talked to Fitech yesterday about my pre- and post-mechanical carburetor pump filters and they didn't think it would hurt anything leaving both but I'm going to pull the pre-pump filter since it's old, I have to replace that section of fuel line anyway, and the pickup in the tank should filter the junk. I will keep the low-pressure mechanical pump filter between the pump and fcc.

On a side note, my in-line high-pressure filter between the fcc and throttle body doesn't have a direction of flow marked on it (or an in/out stamping) but Fitech tech support said the nut side of the filter is the outlet in case anyone else has this issue. Also the return port on the throttle body uses the smaller of the supplied plugs. My intructions said I had three of the larger plugs and one smaller one. They said they needed to update their intructions on this issue and I noticed they talk about it in their latest Summit Racing video online. I should have noticed the smaller threads when I pulled the return line fitting but what are you going to do. :BangHead:

It's at the 9:30 mark.

 
Gents, a quick note. A friend was having his pure stock (no EFI) 68 Bee dynode and the tech spent a lot of time with it to get her tuned in perfect...he knew what he was doing. After the pulls I started talking to him about the add on EFI systems and specifically Fitect because that is my system of choice also. He was pretty well versed on the different EFI systems and had one bit of advice to pass on. He said, some of the systems do not have a memory aspect that will reboot after a loss of power. In other words, if you disconnect the battery for any reason, you go back to the start of a "learning process and reprogram". That was the main fault plus he wasn't that impressed with having a pressurized can of gas in the engine bay. Outside of that he had no complaints. I just though I would pass that on to the group to digest.

The tank is the engine bay is not pressurized. Only the line from the fuel command center to the throttle body is under pressure.

And there service is on top of it. No issues with install at all.

Really clean set up! Love the color and how you did your valve covers. Hope you don't mind a few nosy questions...... What are your engine specs? HP, Compression, Cam duration, inches of vacuum at idle? I'm seriously considering this EFI set up for my 700hp 440ci R3 small block but worried about idle quality and it not being enough CFM. I only having about 6.5 - 7 inches of vacuum at idle if i'm lucky.

I believe the 600hp systems are 950 cfm. The 1200 HP system would be plenty for your engine.

I spoke with FiTech yesterday and the dude there said all of their throttle bodies are 850cfm...... Now, i'm not sure if that means they have the same venturi size as an 850 carb or they actually flow 850cfm..... If it's the same size as an 850 then it'll flow quite a bit more due to the fact that the venturi is wide open and there isn't any boosters getting in the way slowing things down.
 
Just finished installing FITECH on my 528 Hemi. I haven't driven it yet, but it started in probably two cranks with great run-up.

I ended up pulling the trigger as well...... I opted for the 800hp Mean Street setup. Runs wayyyyyy better and uses probably half the fuel as before. Still fine tuning but so far i really like it.

I know that this post was made in July but in the interest of accuracy, I wanted to say that the FiTech unit DOES NOT LOSE the program if you disconnect the battery. And, as has been said, the quart of fuel in the Fuel Command Center is NOT pressurized.

Nice looking install. Once you get it to operating temp, go into your main screen on the controller and find your IAC steps #; it will probably be over 40. It needs to be lower than 10 otherwise you'll experience hot-start issues. It's mechanical adjustment; looks like a idle air screw on a carb. It's located at the front drivers side of the TB. Clockwise lowers the IAC, counter-clockwise raises. It doesn't take much, 1/8 to 1/4 turns in the beginning, less as you dial it in. The engine has to be idling at operating temp.
Also want to dial in your Pulse Wide Modulation, PWM. It's a different setup for each type of electric fuel pump. Call FiTech tech support and ask for Cody, he'll tell you the best setting.
 

I've heard these complaints also...... With the FiTech system, once the unit powers itself down, it automatically saves your learned parameters. So, just as long as you let it power down on it's own before killing battery power, it will save what it learned. If it suddenly loses power before shutting down, it will still have the saved parameters from the last time it powered down..... As for the Fuel Command System under the hood... I'm not running one since i have a sumped Aeromotive fuel pump but, it's not a pressurized can of fuel.... The only thing under high pressure is the fuel line from the can to the throttle body which you would have regardless the fuel supply system you choose to run, although it is a can full of fuel, it is not under pressure.
 
So far no complaints, been running it for about 8 months and she runs great with perfect manners in the morning with warm up along with great throttle response
