FiTech?

Has anyone heard of or have this system? http://fitechefi.com/ I'm looking to switch from to fi. Just checking my options.

I'm seriously thinking about grabbing the new 'small' setup (up to 400hp). All reviews I've seen have been good. I do like the spark control on the next level up but not sure is worth the extra $200 on such a low po motor.

I did the 600hp model cause I wanted the timing control. I'm pretty sure I've figured out how to use the motorcraft distance quite easily and cheaply for the timing control. Figured if I'm going that far to add fi I want it to control everything.
Got mine for $1198 with free shipping from pace performance. That was with the external fuel pump kit. But they are out till March 7th

Just FYI, Holley's "Sniper" kit looks like it's designed and priced specifically to compete with Fitech's kit. It's supposed to drop later this year. Might want to look at both before jumping on this Fitech wave. Dunno, Fitech may be a better kit, but I can easily envision the posts where people buy Fitech and wish they had waited.

Yeah, I saw both of them. I like how it's all in one package with the pcm on the throttle body and option to use the mechanical fuel pump. I'll wait til May when the Holley comes out or if I get a wild hare I'll go FiTech.

I'm anxious to see how these work out. I can't get my head around the timing controls without locking down the distributor

It took me a long time but I think I figured it out lol
I'll post up once I have something. Right now trying to figure out my fuel lines.

You do have to lock the distributor, but to do that just replace the springs with wire. Yeah you have to pull the distributor, but that's not a very big chore at all.

Looks like the next level up from the base 600hp setup (600hp with boost/power adder support) has more timing control points - instead of 3x3,it's 10x12. Still think I might go with the 400hp unit without timing control and fuel center as I could quickly throw the carb back on if anything in the fi setup fails.

I hope I don't jinx myself, but I've been basically daily driving mine and it's great. I did the 400 system and the command center and have had zero issues. Everything about it is better than a carb. I used to have real bad hot starts and now it's like a modern vehicle. I also have msd ignition and a cs130 and I think it really helps.

Your FCC will overheat the fuel pump when it idles for any period of time.

Idle it for about 5 minutes and go out and feel it.

Mines been in now for at least 6 months and haven't had any problems. Where did you mount your command center? I cut a hole in the inner fender where the over flow container is so it gets a lot of moving air from the fan on it, it's never felt warm and it's been driven a lot and idled a lot.

I had mine originally where the overflow tank was but moved it to the fenderwell and built a heat soak shield for it. Had no problems at first too till I idled it for a while in the driveway and the pump overheated and auto shut down.

First thing I noticed was the low pressure gauge not working right. Went the rounds with that, replaced gauge, tore apart FCC, moved location, called fitech support, etc.....

Then I went wheelin. Climbed a hill slowly and idled at the top to take pics and it died till I cooled it off with some ice and got some fast moving air on it then no probs.
Had the wife and kids with me and had them worried to death we were stranded but I knew exactly what it was.

It just doesn't move enough fuel through the can to keep it cool enough at idle basically. The pump deadheads against thenTb, and overheats inside the can.

I wrote up some posts earlier in the year about and I can't recall all the extensive details but since I switched it out for an intank I haven't had a single issue.

Fitech knows this and they've since updated to some different FCCs and delivery systems because the FCC sux while never admitting this problem. I had zero argument about getting a refund for the POS which is good for them and I'll give em credit for that.

And for their FI system other than that is great....

How long did you have it where the coolant bottle goes? And why did you move it? I did read where people had issues with it, but I figured it was because it was mounted by an exhaust manifold.

my jeep never gets above 205 degrees, so it's a cool running motor, also I have a vented gas cap and no emission stuff in the engine bay and new fuel lines and new mechanical pump. I haven't been babying it either, since June I've driven it more than I have probably than the previous 6 years.

Before I got the Fitech I basically couldn't drive it during the summer because I got such bad heat soak with the carb. At this point I'm definitely happy with it.

I've had the base model 400hp version for about a year now. I used their inline setup instead of the FCC, so no issues there. It's been reliable and it runs better than it did with the carb. The only real issue I had is you need to ensure you don't drop 12V to the unit during cranking. This is technically mentioned in the install instructions but it should be more clear. Since sorting that out, it's been great for the price so far. Easy enough to install, and having it all in one unit makes for a clean setup.

Had mine installed since June with no issues. Cheap inline fuel pump mounted to the rear cross member and 31 gallon spare tire location fuel tank. Mine gets almost 14 mpg now and my 2009 chevy 2500hd 4x4 with the 6.0 barely gets 12.. I drive the Jeep more to save money on gas....

How do you compare performance and MPG to when it had the carb?

Can't speak for fitech, but with GM TBI very noticeable increase in performance.
Not big HWY MPG increase, maybe 1MPG, but huge gain in City MPG ~3MPG.
Doesn't sound like much but = ~30% which is pretty significant.
I'd expect similar results from FiTech or Holley...

The beauty of TBI be it fitech/GM/etc., is once tuned, just turn key and go.
No warmup period needed, no setting the choke, no constantly explaining to wife how to start a carb'ed vehicle etc.

They can also be tuned for performance, crappy MPG, but again noticeable increase in performance.
Tuning them for MPG, even better MPG, but takes a performance hit.
All without even opening the hood

Yeah it's a big step forward IMO. Now that it's had a few thousand miles and I've dialed in the stuff it doesn't really do on it's own (idle, fan control temps, closed-throttle cutoffs, and Accel pump settings) it's a nice driving truck. Most noticeable is around town performance...just off idle and stoplight to stoplight. It just feels a lot more modern.
I wouldn't hesitate to do it again.
