FiTECH Fuel Injection Systems
 

This system came up in another thread and to not take away from that OP's thread i figured i would start one on it.

So has anyone used any of these systems on Marine applications? Seem really simple, and you really don't need a lot of the (auto) bells and whistles that the Holley's and Fast systems have for marine use.

What are some of the issues that this system may have ? This Question is addressed to the guys on here that actually tune with EFI on a regular basis.

Honestly they don't tell you much in the description. Like "4 high flow 600hp injectors". I'm a believer in you get what you pay for.

looked at that as well...looks interesting...several make the same looking unit, not sure on their ECM and thats where all the magic lies...could be great though

Laptop software is available for advanced tuners site says. What capabilities it allows is not listed. Site looks to cater to people who want the ease of bolt on and go carb replament. However, the videos on their website show it in a blow through and roots blower application and reports say they run fantastic and idle smooth. I know my interest has been piqued.

I've only read positive reviews so far. I called and asked if they've done much work in the marine environment and they said the biggest hurdle was keeping the O2 sensor dry. I asked about locking in a map and disregard the sensor after tuning and he said no dice.

The have the basic bolt on and go system, or the "power adder" units designed for supercharged systems. I plan on playing with a unit soon. I'll post my findings.

That's too bad.

Yeah I wouldn't even consider a package that relies on O2 sensor data unless I was running a totally dry exhaust.

That was my biggest question. That sucks! I don't see why they couldn't add that to the software.

Anyone here use the Fast EZ system?

Very cool. What does it do when O2 fails?

If it matters to anyone, just doing some digging

The resume' of Jeremy Schmidt is 14 years of developing and implementing self tuning EFI systems. Pretty impressive.

No, actually I'm not. I don't know enough about the systems overall dependability to make that call.

I'm pro american...yes...but....I will not call stuff made in China Chinese Junk until it's proven it's Chinese junk.

Does it raise an eyebrow ? Sure....since, what, 80% of things made in China is junk......but again, that doesn't mean something is until it's proven as junk.

Just wanna make this clear.

Helped with the installation of 2 systems a couple of years ago on 2 540's. They need constant O2 feedback and will not work with forced induction. 1.5yrs on the O2's and boat runs great. Pretty simple systems.

Yes I already said in another thread that they are not USA made but left out the China made because I did not want anyone to think up front that it was pure junk system. I met the owner in person and he even told me were they are made China. He seemed very interested in making head way into the marine market. He also wanted to know from my end how are the marine OEM EFI set ups and my opinions. IMO he really cares about his products and wants to keep them entry level pricing but try to offer best bang for your buck kind of deal.

I have no experience with USING his systems but did spend alot of time looking over them in my hands. They actually looked good in person. just saying

I edited, sorry for drawing conclusions.

In case there is a little doubt left, has one has heard me say Scat forged stuff is junk ? Nope.

I have an inquiry to them about using their new and yet released MPI system with twin turbos in a Marine environment. There is a post on one of the forums about using the TBI version with a Procharger with good results.

The literature says the new MPI system will take boost as it comes with a 2.5 bar MAP, spark control/rev limiting and all other sensors contained in the throttle body, apart from a water temp sensor for the intake and a 02 sensor for the pipe (which can not be tuned out) Entire system for up to 1050hp is $1995, turnkey. I have all the intake stuff, probably go ahead and buy new injectors, so deleting those items from their "package", the stand alone electronics package is $1295. 6-wire hook up and your rollin'.
When you're talking about two engines, that's a heck of a savings! Even made in America stuff is often just "assembled" in America using Chinese stuff. Looks good, but so do alot of mean women!!! lol! Only time will tell.

Do you have a link about the post in the forum? I'd like to have a look at that. I don't need any links to mean women as I've got that covered. ;)

Fitechefi.com

I tried to find the exact link I saw, but looking back, couldn't find it. It was in the comments to a youtube post, the guy that owns the company built it. Google Fitech EFI Procharger and there are several forums and reviews.

I saw in the Youtube post a guy running a blow thru turbo at 9lbs. no problems.
Interested to see what they say about the MPI system under boost. Everything I can see about them, down to tech support, seems great.

Here is my response from Fitech:

Hi Charles
I don't have a timeline for the go port's release just yet, but
hopefully within the next couple of months.
Our system is probably the most plug-and-play you find.
Our ECU will control the timing, the pickup and distributor must be a
two wire magnetic pickup, nothing else will work.
Our system will offer full timing control with boost timing retard, it
will support up to 25 pounds of boost.
Our fuel pressure requires a constant 58 psi, the volume depends on how
much horsepower you're trying to produce 340 LPH pump support up to 800
hp on forced induction.
Any custom harness modifications will have to be done yourself, all our
systems are premade.
They been holding up to Florida airboats in a few other things, but we
are not Coast Guard approved.
Or do we make any claims to be Marine friendly.
Just to build a proper and adequate fuel system which would be
determined by the amount horsepower you are going to cover.
Any other questions let me know

Pretty impressive. I'm going to be building my Mustang soon and need a new fuel injection system. I might just buy the 600HP version for it seeing that it handles boost. While I'm building my 347 I see no reason not to run it on one of my 454's. I'll be a guinea pig. :)

will someone please post a pic of a Chinese Junk so everyone knows what we are discussing here?

Ok, followup. First let me say, great customer service!!! They have emailed me and called me multiple times concerning my questions about supercharging/turbocharging their system.

Now, ALTHOUGH they tout that they have "supercharger ready" systems, that is a bit of "misnomer" at this point. Because their initial offerings were designed to hit the biggest demographic, the carb-to-efi swap, ALL of their sensors (except temp and o2) are built-in the TB and they read exclusively off the TB ports. At this juncture, they have no way to read "boost" through the MAP sensor unless it shows boost at the TB, and since it is not able to be modified to externally reference, there is no way to show the computer real-time "boost" unless it is BLOW-THROUGH at the TB.

To Use it in it's current configuration for "draw-through" EFI (like a roots system or intake side turbos), you generally set it up as a "Carb". You do get the advantage of 02 map changes and the ability to change things through their interface screen, but you have to go in manually and set it up to change spark functions, etc. The tech recommended just using a standalone dist and box like MSD. I was totally bummed. I had it in my brain that their yet to be released MPI system would bolt on and go, but not so.

Not to give up hope!!! He said they were testing to provide an EFI system in the same price-points where the MAP could be externally referenced to read real-time boost from the manifold and control all aspects of a boosted engine, just like it can a NA engine. (Like they advertise now, but can't) He projected in the next 6-8 months that a full (and truthful) "boost-ready" root type blower system will be available that is fully self-contained and self learning. Type in CI, boost perimeters (advance, retard and AFRs) and hit the key. Less than $2k Multiport EFI per motor and a 6-wire hookup!

For NA street rods, Procharger/Vortech guys, this appears to be great stuff. I have time before I turn the key on my Resto, so I can wait.

Great feedback!

I have a Vortech and want a system sooner than later and plan on pulling the pin this week for the 1200hp adder plus system and will keep you all posted. I'm curious if it would be worth waiting for the MPI system?

For you it looks like a piece of cake! Bolt on, change the water temp sensor and drill a hole in your exhaust for the 02(They have a Clamp style bung that doesn't even need to be welded) and hook up 6 wires. Answer some questions and fire it up. Takes a bit for the ECU to figure it all out, but gets better as it goes they say.

So this is a lie?

....

NO no! not a lie, just not very clear. For a draw thru system, you set it up manually like a carb and the O2 will adjust the fuel map, which is what they did in the video apparently. The video SAYS the timing was "locked" at 28 degrees, meaning the ECU was not controlling timing in this configuration (because it can't). All that is correct and follows what the tech told me exactly. However, unlike a carb, the 02 WILL read the AFR, "self learn", and adjust on the fly, and any other changes can be made through their hand held monitor if you don't like something. Great advantage to carb, just not a complete plug and play on draw thru.. If you wanted spark control in a draw through, that will have to be with a separate system not tied to the ECU.

What you have to watch out for on draw thru is the advertising telling you that on draw thru, they read boost (up to 25lbs). and can control SPARK and all is completely self contained and self learning. There are some ads (Pace performance) that say Fitech has "Blower Ready" systems, and they show a Roots blower. The system currently (by my understanding) operates with a blow thru system up to 25lbs and will control spark, and in that configuration it is plug and play for a boosted motor.

Hate to say it, but aftmkt fuel injection without timing control is so early mid 90's. I'd pass !

"Supposedly" within the next 6-8 months they will have a TBI and MPI system that will have the capability to read boost on draw thru systems, and be completely self-contained and control everything. I'm at LEAST that far away from firing engines, so I think I'll wait them out!

If I understand correctly, it does control spark, just not for boost referenced apps yet (ie no reference port). For NA and blow through it will do spark.

I don't see why blow thru or draw thru would be much of a change, I would imagine they run a MAP in the ecm, the mega squirt stuff we use does and thats where boost is picked up. They have a couple different MAP's depending on boost level, also I called and talked these guys about a year ago and was told they were working on their boost ready setup and would be ready in the future...guess thats now

That doesn't make much sense. A draw thru does not have the throttle bodies in a pressurized environment - they are open to the atmosphere, the blow thru's are subected to 'boost.'. Remember, the injectors are in the throttle bodies.

Either way, if an application is not supported with ignition timing I would pass.

The feature it doesn't have is the ability to reference the boost under the blower, so it could not pull spark when the pressure went up. The MAP sensor is integral to the throttle body, so on a blow through, it would see the increase in pressure and could pull spark.

Would work on a pull through blower, but not for spark control - unless you locked spark or had a separate controller.

Every system has it's limits and trade offs, even Holley, etc. I'd think the market for NA is huge. boost-referenced pull through blowers not so much. They went for the market niche of NA, where it is a complete system. Blow through boosted apps are essentially NA with some software and MAP changes for the pressure situations.

Ahhhh ! Thank you Kemosabe (sp?) - I simply didn't see (or comprende or got old and forgot) the map sensor was internal to the throttle body.
I'm used to MAP sensor directly connected to the intake manifold.I thought it was a programming issue they had. Totally makes sense now. Thank you.

It seems that more often than not folks lock out the timing anyways so in that case it's a non-issue, right?

Apollard--That was my understanding. The change they anticipate is simply a port to externally reference their internal MAP, allowing you to run a hose to a nipple below the blower and reference your vacuum and boost there, and control everything else based on it. At the price point he suggested, it's hard not to go with them.
