efi systems

[tamanaco]

anyone installed FiTech efi system? Products

can be used as a standard suck thru or as a blow thru for turbo/blower car. clean looking installation...looking for any feedback.

Looks like a good system.

I'd buy one.

Hardware looks nice cosmetically, and the price is right. You'll get better performance if you don't mind seeing a pair of fuel rails and go with the edelbrock victor EFI manifold and 4 barrel throttle body and stand alone ECU. I'm fond of Megasquirt.

Be aware of the learning curve of tuning and don't think an auto learning unit is smart enough to auto tune without a good bit of guidance and correction. Read Prof's experiences. For that matter, look at Bob Cowans (may have misspelled) hair removal getting a reliable crank signal on his megasquirt install.

Mu biggest question is how much flexibility and control their little touch screen interface has. I can't imagine doing what I do with the laptop from a little proprietary touch screen.

There's 2 ways to install EFI.

1- Pay a lot of money for some shop to do it, and make sure they can tune it as well and be prepared to go round and round saying no this isn't good enough,

2- Spend a lot of time learning how to tune it yourself.

I recently installed the Fitech Go EFI 8 on my car. I haven't had it long enough to explore all the possibilities yet but it gets better every time I drive it. Happy so far.

Any updates on the FITECH?

[G_Edmonds]

I still only have a few hundred miles on the Fitech. Full throttle power is very good but then, it was good before with the carb. The advantage for me is drivability when highway cruising or other part throttle situations. In reality that is the majority of my driving. It definitely meters the fuel better in those situations.

G_Edmonds, How much effort was required for the install/programming? Or did everthing go in easily? Thinking of the same thing for my Cobra.

[G_Edmonds]

I used the Fuel Command Center and that was the hardest part of the install. If you just put a high psi pump in the rear it would have been very easy. The tuning was another matter. They send you a list of definitions of all the things you can adjust but no advice on how much to change. Their tech guys are very helpful when you call though. After a call or two and a lot of searching online, I've got it starting easy and running really well. I really like it so far but as they say, time will tell.

[spdbrake]

G_E are you using the timing feature? I'm so far not really happy with it controlling the spark but its only been running 4-5 miles so far.

That was the biggest problem I found with my holley setup. It took a while to learn what all the functions did, but that is do-able. The problem is that I couldn't figure out what my motor wanted. I asked online a bunch of times... What base timing, what max timing, what AFR, and the response was always "you tell me". I kept adjusting timing, fuel tables, AE vs TPS, AFR target, etc. I even took it to a "professional tuner" and it came it running just as poorly as it did before.

I went thru three WBO2 sensors at $130 each. The last one went while I was on the track at Harris Hill Raceway, ending not only my track day, but the entire Texas Cobra Club meet that I wait all year for.

I think these are good systems, just finding the right tune seems happenstance. There is no stock 408 stroked Ford, 195 AFR heads, 2400 pound, manual transmission, 9 inch rear with 3.73 rear gears tune.

I ripped it all out and went back to a nice quick fuel carb from Blykins. If anyone wants to try a Holley Terminator system, I've got a slightly used one for sale.

[G_Edmonds]

spdbrake, in my application the unit can't control the timing. From what I've read, if you have your timing pretty well lined out already, the Fitech won't really improve on that.

Probably should have gone with a HP or Dominator system. Both work excellent on engines with a lot of mods and big cams.

The Terminator system is a HP if you connect a laptop. I gave up on the handheld after the first day.

That doesn't seem to be the way they are listed on the Holley website. It looks like the HP is a different line than the Terminator line.

Excellent?? I recall a thread on here where Vintage Motorsports our backdraft dealer ditched this system because it did not work. For everyone who says they love these self learners there are countless threads where 5 can't get them to work. One is the az cobra club on here stated he tried the fast ditched it because Bob Rhem efi expert could not get it to work with a big cam. He went back to a carb. It may work for some and not for others. Seems strange.

One thread on here titled. Breaking down efi options. Many complaints about the self learning systems. I can link the thread for some reason. A search easily finds it.

Funny, yet I visit a site that is dedicated to LS engines and they are running 1400 hp twin turbo E85 engines with 11:1 CR, massive cams, 7500 redline etc..etc..etc..and that is all they run. And they drive them on the street. Heck, my factory EFI handles a cam with 250 dur @ .05 and well over .600" lift and it will run with the MAF sensor and in closed loop. My cam isn't even that radical.

I wouldn't rely on the self tuning to run on a daily basis, but it seems to work decent to get the car fired and put on a few miles so you can fine tune it.

Maybe people just don't do their research enough or think they can get by with a cheap system. The Dominator is definitely not cheap and it has a large learning curve, but it will do whatever you want it to do.

The Holley self learning system won't support 1400hp. The Holley dominator is a multiport system. 2 totally different efi set ups. Lol

I have been using Big Stuff 3 (BS3) for the last few years. It works well, has good drivability, and makes really good power. My Turbocharged factory Five makes 924hp/ and 986wrtq on around 18 pounds of boost. BS3 also has great Data-Logging, when you plug up a laptop to the system. The car makes more power than you will ever need!!
