Need some ideas on Marine Fuel Injectionion
 

Who has heard about or is running a good marine fuel injection system that they would recommend to a feloow offshore member. Lots of systems out there, who's system is not working in marine enviroment as well as who's is doing a great job. Ideas would be appreciated.

What are you doing and what are you building? What do you want the EFI system to do?

Trying to improve the driveability as well as how clean the boat runs. I'm tired of wiping the black off the transom every couple of hours. I have a Procharger system with dual carbs and there is just not a happy medium, either fat in the middle and runs great on top end(plug readings), or the other option, let's not even discuss, a great cruise and lean on top. A friend is trying the Nickerson blower carbs for blow thru carb systems, but he hasn't tested them yet. I feel a fuel injection for the marine application could do it all, I think we all we have that conclusion eventually, after the bugs are worked. I would think with all the great ideas floating around this board suely someone has tried this, or has researched it to the point they hit a snag, like cost.

I have been running Haltech electronic injection for 5 years. It is a trouble free programable ecm. Not cheap but then the good stuff never is. The ecm can control all ignition functions as well as fuel.

Which Haltech are you using is it the F9 or F9a?
Did you piece together your manifold and throttle body with the rails, and buy the Haltech ECM, or did you buy complete.
Where did you get you system?
Do you have TPS and IAC motor?
Numbers and details would be very helpful.

Has anyone tried the Commander 950 sytem on a boat?
Looks like it would work great, naturally aspirated or supercharged. Here's their website post, copy it and check out all the systems. maybe we could get an Offshore package deal if anyone else is interested.

What about Total Control by PFM Products the superchiller people. That is what I am going to try this year.

I'm going to add my .02 here . You obviosly know a thing or 2 about FI. I'll just state my point. the main problem Wtih aftr mrkt is they need a o2 to accomodate all the different engines for fuel mixture. 02 in marine is a problem.
factory engines have set fuel maps so 02 is not needed . they way i see this is you could look @ mechanical FI (kinsler) or fork over the cash to have a ecm burned to your particular engine fuel map. Now i'll step back and wait to be corrected in my misinformation. please correct me if i'm wrong :D

Try Ariszona speed

The tech people at Holley state that the oxygen sensor can be welded in to Lightning headers with no problem, and the fact I have the dry to the transom makes it even better. As well, once the computer programs itself to the motor, it no longer needs the oxygen sensor. Keeping in mind that it will follow that one program it has just written itself. Sounds great now will someone else try it first, so I can be sure, before I plunk down my 3 grand.
I did price Arizona Speed and Marine and they are $4500.00, and there's runs off E-prom, which is preprogrammed for particualr application, not as flexible, and a lot more.

I am currently using the Haltech e6s. The f9 and f9a are older models. The intake is actually the old Cutler unit which I think was bought out by Holley. I do use an o2 sensor and have had no problems with it. I am using 140# injectors to support the hp output. I also have iac motor and tps. Using this set-up I have been able to run a pretty wild cam and still make motor idle at 800rpms. Unlike the Holley system, the Haltech will not "learn." It has to be programed and the program doesn't change unless you change it. Previously had a Cutler system on my old NA motor but it did not like much over 600hp. Don't know if Holley has figured that out. Hope this helps.

Why not just buy a used system off a 454/502 magEFI. Can get complete for about $1000. Then what ever the motor specs and hp have ASM burn a new program in the computer.

Do you need it to be user programmable? Do you have an O2 sensor and A/F ratio meter to tune it? You can convert any manifold to EFI for about $500.

Electromotive is another good choice and prices are not bad and been in the business for longer than most.

From what I was told, Holley FI systems (which is the old Cutler system) has still not been improved upon. The Halteck is a user friendly system and will work well with radical cams. The Halteck computer can bee used with the Holley hard parts i.e. intake manifold, fuel rail kit, throttle body, etc....it's just that the Holley ECU program is not a good system. The guy who dyno'd my engines is an engineer for fuel injection systems. He's well versed in the marine industry and has been hired in the past by Merc for R&D dyno testing. He's in his late 50's, is incredibly intelligent, has vast knowledge and experience what it takes to make a marine engine survive with good drivability, etc, etc. Heck, he even builds twin turbo applications with the Halteck fuel injection system. This guy is no B.S....he does not have time to horse around---very straight forward and is highly respected by those who know anything about marine engines in the western Michigan area.

Talk to ASM They have complete packages. $3400.00 includes even a Distributor.

Great idea Kaama! Thanks!

electromotive gets rid of the distributor and has the abilty to program fuel and advance retard

JS- how much HP are you wanting to make? This should be the determinig factor as to what type of FI system you go with. The plenum/long runner types, for all their advantages, become unhappy in short order when the MAP sensor doesnt receive a stable vacuum signal at low RPM's, resulting in dirty transoms and instability at idle. The long runners and big plenum will magnify any intake reversion present. The nicest running of this type system on a 502 runs a cam shaft profile not much larger than 225/230..... I know this seems small and it might net you 500hp w/ some nice parts. The system on the HP 500 EFI is already at its limits [from an OEM standpoint] with its 230/236 114LSA cam, though you could get a little more w/ better heads and longer exhaust runners.
If you want bigger power, then you need to go with a shorter runner length, say less than 7"[usually found in single plane manifolds] as this type of manifold will be more compatible with the longer duration camshafts.
Also, IMO, I would "can" the o-2 sensor on a boat unless you are running dry exhaust, I just think you find it to be more of a problem. I think that there are many FI specialist out there that can make speed density systems operate just fine without it.
If you want a 600 HP FI engine, call Innovation Marine, I'm sure they would duplicate the sweet little set-up they used on the Volvo 600....with the bugs already worked out of it. Just my opinions- hope it helps. Good Luck!

If you can wait about 2 weeks i can tell you how the holley system works on the dyno with hp500 and m3sc prochargers, mine have been on order for about 5 weeks that is all i am waiting for.
i had the same exact plroblem with prochargine carbs. making great hp dyno 720 hp with m1 but no way to get the rich lean problem to go away. Hope for this to take care of it.
keep me posted of your progress.

Hey thnks for the input on the fuel injection, I really appreciate it.
Guillermof, it would be great to hear from you how your project with the Prochargers works out, that is about the same boat I'm in, 540 BBC with stage 4 procharger. Please email as soon as you have info. Another boardee, tubrbojack is setting up a stage 4 for his boat and would appreciate the info as well.
Thanks
