Engine Managment computer

[Byrdman]

I'm looking for a good fuel injection/ engine management computer that will work with the new Ford SOHC 4.0
Anyone have a sourse or company name they could turn me on to would be bitchin. Thank you- Roger

we use this in our 10 car and works great and i have seen it used in a 7 open ranger at the 500

[Byrdman]

Thank You. How much does the complete set up cost?? Thanks Again

The prices are on their web page, it's by far the least expensive system and it works very well. I've heard that they can't run with some Ford motors so check it out for your specific motor. Ross is their tech and sales guy, he's very helpful. We have been running one in our Toyota for 4 years without any problems...Curt

Motec has great systems, but they are a lil pricey.

Byrdman,

PLEASE check the rules before you go that route. I don't have a recent SCORE rulebook, but my recollection is that aftermarket injection is not allowed in any 7 class.

BITD RULES:
7100 (7S): "SCR17: IGNITION
Vehicles with 4300cc engines must retain the vehicle manufacturers stock CPU computer as delivered by the factory."

CARBURETOR
3000cc engine rule
"Any make of carburetor or fuel injection may be used but must maintain a maximum of one venturi per cylinder.

4300cc engine rule
Any make of carburetor or stock production vehicle manufacturers factory fuel injection may be used but must maintain a maximum of one venturi per cylinder."

7200 (7 Open):
"Any make of carburetors permitted with a maximum of one venturi per cylinder.
Stock fuel injection is permitted."

7300 (Pure Stock):
"Any make of automotive carburetor(s) or factory stock fuel injection may be used, providing they maintain a maximum of one venturi per cylinder. Any OE factory intake manifold set (upper and lower) appropriate for the engine may be used. Upper intake manifold cannot be modified.

Any make of intake manifold may be used for carbureted engines only."

Now, I've never heard of anyone getting busted for running aftermarket FI, and it certainly isn't an issue if you don't plan to race. We all know there is no such thing as enforcement from the sanctioning bodies themselves. Just thought I'd let you know.

I'll second the SDS units. I have put mine through hell in Baja for 3 years. This includes full submersion (not recomended). Just drianed the water, let it dry in the sun, pluged it back in and drove off.

[Byrdman]

IF I were to run the new motor, I would use the stock F I and probably run an aftermarket computer. Computers are open according to Savage at SCORE

[johnnyweb]

what class are you looking to run the truck/car in?

[Byrdman]

Class 7s at SCORE

[drtdevil93]

ive heard more than once that for the 4.0 sohc, motec is the only system that will work. im not sure why.

Sorry for digging up such an old thread but when SCORE says "stock fuel injection" do they mean the physical injectors and not the computer? IOW as long as I use the stock injectors I can use any computer that I want (like Dan Chamlee did here... http://sdsefi.com/ )?

How about for ignition control, anything restricted there (electronic vs dizzy, etc)?

Thanks folks.

Howdy Byrdwman!

Call Steve Dose of Lethal Dose in Santee, CA. He offers, services, and tunes Electromotive and Motec. I am very impressed with the latest Electromotive TEC3. It is both durable and their coils offer the most powerful spark that I know of I have seen many 4.0 pushrod and OHC motors w/ them as well as some 3.8's.

Steve can be reached at (619) 449-3835.

Good Luck!

There are many aftermarket ECU's that will work. MoTeC, EFI Technologies, Pectel, Life Racing, AEM, etc... All the above have configurable inputs for crank and cam position signal, along with adjustable dwell time for various coils with and without internal coil drivers. Ford Coils are fairly good by the way.

We use Accel DFI on 4.0 SOHC motor. It works pretty well.

[CRAIGHALL]

Just to add.. Stock will work in another chassis,you just need somebody to reconfigure the stock computer.

[SimonSays]

dont know if someone has mentioned simple digital, thats what we use in our class 7 race truck, it works great and its not very expensive at all. cheaper then reprograming the stock computer. it is avaible to use with fuel and spark or just fuel(if you want to use a msd distributer or stock distributer) very reliable too, we have never had a problem we have the computer in a water proof container and even if the motor is completly under water going though a creek crossing we NEVER have had a miss.

Install is easy too, you have to pull of the harmonic balancer and glue in 3 magnets, bolt on a bracket that reads the crank position off the harmonic balancer and plug into the stock fuel injectors, if you are gonna run spark off it too you just have to find a spot for there spark box and plug in the spark plug wires.

once you have it installed, its time to take it to the dyno and tune it
you have rpm inrichments
map inrichments and tps inrichments so it gives you a very stong and consistant powerband.

You really use SDS in a race vehicle? Wow! I would bet that the stock ECU is more powerfull than the SDS unit. There are quite a few guys that are proficient with the mapping of Ford ECU's...

Depends on the Ford your are talking about. for the older speed density 351W's it's a way better set-up. Also, if your starting from scratch is more cost effective. Yes there are plenty of guys around that can tune a stock Ford computer but a couple trips to them would pay for an SDS system you can tune yourself, no laptop required. They are also bullet proof. They can be submerged in water and filled with mud and still work fine when dried out.


Having used both I would never go back to a stock computer.

We will never go back either, infact i want to change my prerunner to the SDS system.

4.0 SOHC with SCT programming and performance components.

We bring the lap top to tune and reprogram if need be. No hassles!

no hassle except when you dont have a computer to use. the nice thing about the sds (simple digital system) is it doesnt require a computer to tune so if you got a problem on the course you dont have to send in a laptop only a programer

[baja619]

That is why we either bring the laptop with us or have our pretuned alternatives to swap out for the best performance under the circumstances.

You got alot of good feedback on your system and it seems to work for you.

We prepare for what we need and more, No hassles!
