Complain to mods and management?? Not worth it. I made that comment for entertainment only, not because I really care.

5-10 off topic rants?? Thats a stretch if not a lie on your part. Why don't you set an example for others by being an honest individual.

 

You can in fact run two EFI computers in parallel, but you're opening up a huge can of worms and it's not an easy project.

I had to do this in my 93 Continental because I sunk a bunch of money into the FWD V6 and installed a paxton supercharger, and the factory EEC didn't like this at all. Since my knowledge of EEC at the time was next to nil, I ran the engine off Electromotive's Tec-II EFI controller which was more than happy to deal with the forced induction as well as the increased redline. The Tec-II had no facility to control the AXOD-E transaxle (very E40D-like in wiring and control) nor did it have any interest in the factory four-corner air suspension that these cars have. So I had to use the Ford EEC to manage the suspension and the trans, and use the Tec-II to manage the engine. Of course the Ford EEC uses Ford sensors, and the Tec-II uses GM sensors. The wiring harness I had to make was ... um ... interesting

And you will have many quirks to deal with after the fact. I could give you a list of mine! In a situation like yours, I would recommend using factory parts and EEC controller if possible, even from a later year, where you can get all the functionality you require. It would be much easier to perform that type of upgrade than to combine two EFI computers and have them work together.

But it can be done.

 

If you don't care then why complain? It's not even slightly entertaining in the midst of a technical discussion.

Sure. That was your fifth irrelevent whine/pout/rant/pretend-humor post right there for this thread.

 

If I did not find it amusing I would not have said it......................OBVIOUSLY.

I ranted about things being off topic (thats what an "off topic" rant - as you would call it - is right???) in this thread and one or two others. Not at all 5-10.

Anyways, this is getting beyond petty an it's entertainment points are way down. Come up with something good or I am not responding.

 

I find that Frederic's post was within the basic conversation of this technical discussion.

Lets be realistic here...we're talking EFI...SD is EFI related...it's not like frederic started talking about his mom's chocolate cookies...

Eco, I find your posts to be interfering with the discussion more-so than any of the others in this thread.

See the "Report bad post" button? You are welcome to use it to report bad posts to a moderator.

Otherwise, join the conversation only if you wish to engage in the technical discussion at hand.

This is a good thread, I'm not dumping it, and suspensions will be given out if we do not behave...

I havn't gotten around to writing this...and I'm not sure what I'm going to do about it. I had the thought of making a plug/play kit and offering it as an alternative to the overpriced options that remain in the market. Theoretically, I could make my own harnesses and offer them to consumers as a plug and play setup for their vehicle. It will take the hassles out of doing it yourself...

 

I have an '89 f150 302 with an AOD tranny. I also have an M-9000-T50 MAF conversion kit. The kit is designed for a manual tranny. The T51 is designed for an AOD.

Can I modify and use the T50 kit? The PCM is for a production '93 mustang with a strategy of A3M1. Only the function of pin 30 (NDS) is different between the two systems.

I could return it and get my $500 back.

I hope I did not hijack this thread.

Thank you,

Running/wiring two ECU's is more time comsuming for a mass air swap on these trucks (using an ECU from the A9 family for the engine and stock ECU to control the trans for trucks that are eqiuped with E-transmissions).

The engine and transmission can be controlled by two Ford ECU's; one for the engine and one for the transmission. Pro-M did this and now PMAS does it as well. I can tell you that there is almost twice the wiring with a dual ECU EFI management system. I purchased a Pro-M mass air conversion harness for my 5.8/E4OD 94. I also had a Ford mass air harness at the time and put both of them side by side. The Pro-M harness was the ultimate spaghetti dinner compared to the Ford harness, and the ECU that came with the Ford kit was/is able to operate the engine and transmission, and it responded well to aftermarket tuning. The Pro-M harness was wired to utilize an ECU from the A9L family and use your stock ECU to control the trans.
Tuning was also more complex as well because if you wanted tuning for the engine and transmission, you needed two chips. And as complicated as the E4OD is, aftermarket tuning is almost as important for the trans as it is for the engine. Honestly though, using an ECU from the A9 family is actually a step back compared to the mass air/E4OD truck ECU's. If I were to do it on my own, I'd find an EEC-4 mass air/E4OD ECU to use for a project like this...but that's just me.
I also do my own tuning and having the ability to make changes with one databse and one chip, (for trucks equiped with an electronic transmission), is easier.

 

a mechanic (kindof a ford hating chevy-lover) told me that ford changed the shape of the plugs every year on the ecm. (he also said you can build a 350 for half the cost of a 302) but i haven't been around many 93-95's. i know my 92 is batch-fire sd/e4od and i know the 96's where maf/e4od's with the obd2 getup. but the 93-95's are a gray area to me. if the lightning's where mass air'd in 94, where all trucks mass-air'd or just certain california one's? i've heard and read so many conflicting answers by now. mustangt221 i hope you good luck on this, you're the answer to everyone's frustrations if you can pull this off. far better than holley

 

Mustangt, I think you'd get a fair bit of interest if you made a kit to sell.. as far as I know no one creates a plug and play kit anymore. I don't have much experience electrical wise and I do plan on using the PMAS kit but I am a bit wary. Just letting you know that at least my personal interest is there. Would you use a mustang ecm in your kit or can any ecm (MAF) be used?

 

That kit will work. Just verify that it has the correct injector firing order. There are two, a 302 firing order and a 302HO/351 firing order.

Those kits do not allow the use of dual o2 sensors and they do not allow the use of the canister purge valve function. It will not interfere with operation but is good to know.

There are a couple of ECMs that could be used. I'm thinkin' about it...a lot. Might happen.

Then he's old school and isn't very up on the EFI stuff. Years ago a 302 used to be more expensive to build than a 350, but now the popularity of a 302/351 has skyrocketed and it's roughly the same money.

Also, they didn't change the shape of the plugs every year. Every truck from 87-96 that is EFI is what's called EEC-IV EFI. Yeah they have different computers in them from year to year as they had very minor programming changes and such but all the computer connections are the same 60 pin connector. The sensor plugs had minor variations over that span but nothing drastic like every one of them being different. Lets be real here, unless they have to change it they're not going to, they want to make them as universal and easy to produce (cheap!) as possible.

 

At first I was against this swap. My 93 5.8 runs well stock. But i dont have my hotrod mustang anymore , my truck might become my hotrod. Sooo MAF would be needed for cam and head changes I guess. One question, would a stock SD setup work with SD CompCam and GT-40 heads without a custom chip burned. I wouldnt know where to put the chip. Motor I can do, computer work, I havent done before.

 

All of the GEN 1 Lightnings were/are speed density from the factory. Several years ago, Ford Racing offered a mass air conversion kit that was basically a lay-over harness, with larger injectors, 80mm MAF, ECU and relocated the ACT sensor from the lower manifold to the air box.

 

Justin,

Thank you

OK. So what would a MAF swap do for a 94 F-150 with a 5.8L,E4OD 4x4???I know it goes from a batch fire to a SEFI.Will this help to improve fuel milage?I know the 5.8L are pigs on fuel but I would like to get better fuel milage since this is a daily driver.Also is a Lightning PCM an upgrade for the 5.8L or will it even show a difference?

 

My mind is still reeling from all 7 pages but has anyone else seen this seems to help me with my 92 f150 e40d anybody else? http://eecperformance.com/mafconversion.html
