Ok, I've deciced I need to do a MAF conversion on my truck due to the mods I'm planning to do. I've done some searching and haven't uncovered much, also my net connection is so slow I can't read thru the 255 results that come up My truck is 5sp so I am wondering what options I have to pilfer my parts from?

5.0 Mustang conversion? I know I have to get the truck intake "Y" thingie and airbox lid on my own.

What ECU #'s can be used?

I think I can piece this together fairly inexpensively just need some imput on which parts to gather. Thanks in advance.

 

89-93 Mustang, 5.0L mass air computers are the most common choice.

There are kits to convert the truck's dual TB hoses to a single, no problem.

Another option is to take a piece of 3/8" steel or aluminum, and trace the gasket of the F150's dual TB's mounting holes onto it. Drill those holes out.

Then take the mustang's, single bore TB's gasket, and center that on the plate and mark the four mounting holes as well as the center bore. Use a hole saw in a drill press to bore out the center hole, and drill and tap the mounting holes.

Then test fit everything. Once you're sure it fits nicely, hack out the tiny bit of aluminum (on the F150's upper intake) that seperate the two bores. There's enough meat three you could use the same holesaw, center it, and bore a round hole.

Then put on the F150's dual TB gasket, your metal plate, the mustang's single TB gasket, then the TB itself. Bolt it all down, and you've completed your dual TB to single TB conversion, and can use mustang bits and adapt hoses to your liking.

Another option, is to do the above, but instead of using mustang parts, use 92-99 Crown Vic parts, from the throttle body forward. The plastic air hoses are long enough from the airbox that it will reach easier and you'll have less adaption to do. And, you can still use the 89-93 mustang computer (A9P, A9L) which gives you access to all the tuning software that's out there.

 

need some more info if you could is it a 4x4 or 4x2 and computer #on your truck is what now? ford racing make a EFI mass air conversion kit part # M-9000-T50 for a truck m/t designed for firing order 1-5-4-2-6-3-7-8.check it out or call talk to tech hot line there real helpful.and this kit comes with everthing you need.

 

My truck is 4wd, I will look for the existing computer # this afternoon

 

ok here some info i have a 1994 F-150 4x4 E4OD trans with mass air from factory had a 5.0 took it out and put a 5.8 in.The computer was a HOG0 took that out put a AKCO lighting mass air conversion system it was an experiment my brother bought it for his lighting.Now the only thing I'm using is computer and air meater cab.for 30LB injectors now this work well the reason i switch computer is it give me more tunning opections for a computer chip and i can run it with out the chip if i want now the only thing is i don't have 4-low the truck has shift on the fly auto locking hubs so the stock computer may have some control on that.But i do git 4-high

 

My truck has the mechanical Transfer case and 5sp manual, so I don't have to worry about tranny control or anything like that. I've located an M9000-T50 kit that is brand new but missing the computer, has everything else. If I can get that and then find a computer I should be set right?

 

so your good on the 4-weel part do you know what injectors you are going to go with

 

I just want to use stock injectors, I'm looking to add every mileage minded upgrade I can get my hands on. I scored a free 4" exhaust from a newer diesel that looks like it will go in with a little massaging from the mig welder, and couple this with some headers should get me a few more mpg. My experience with some 5.0 stangs hasn't been that good on the old air density setups when you add performance headers, exhaust, no cats, etc, they don't run well.

 

Went on fordfuelinjection.com lookin for a computer for that kit you found and not much of selection for a truck but found 2 computer under a 94-95 mustang one was J4J1 MAF manual trans or T4MO MAF manual trans look like wood work with that kit you found.or you can use a A9L will work too.

 

I can say, from experience, speed density will work with some bolt-ons; headers, exhaust and CIA, without tuning. The only limitation with speed density is your cam selection. The mass air conversion will should increase about 2mph (depending on your driving habits and condition of your rig), and throttle respsonse will be quicker too.
Doing your own conversion will also save some $$ as well. Eric (EPNCSU2006) has a link to a mass air conversion. If he sees this thread, I'm sure he'll post the link.

 

I'm assuming you mean an extra 2 mpg...that's worth it I think. I've read that it converts from batch fire to sequental which is probably where the extra mileage and power comes from. I've read about people having to rewire their injectors is this true or does the included plug in harness in the conv. kit(M9000-T50, the one for my truck) take care of everything?

 

Nevermind that last post found it. There is a adapter plug that goes between the old harness and ECU on the ford kits, then the rest plugs in, you ground the unit and tape off the old injector plugs and wires. Seems easy enough.

 

Yes, it's that easy.

Actually, you can do the same thing for nearly free. Visit a junkyard, and find yourself a V8, mass air ford of any kind, and take the wiring between the mass air sensor and the EEC connector, and the injectors and the EEC connector. If your yard wants to rape you on a complete harness, pop apart the EEC connector and take the pins out for the mass air sensor and the injectors, roll them up and call it "connectors with some wire for splicing". When you get home, pop the wires into YOUR EEC connector, move the pins around as necessary as per the wiring diagram you're using, and you're all done.

Or buy a several hundred dollar aftermarket Mass Air harness from ford or someplace else.

Me, I'd rather pop EEC connectors apart in the junkyard. It's worth the extra 5 minutes.

 

I have a buddy that got the conversion for his Stang and didn't use it because he got a wrecked lower mile maf car and swapped the whole thing in, but the ecu is gone so he's gonna sell me the rest of the conversion for $200. Otherwise I will be junkyarding for the parts. Reason I prefer not to junkyard is I have to go south to Seattle which I don't have time for. Our tree huggers have gotten so many of our local yards closed only 2 insurance scam yards are left they charge like 80% of dealer list and you can't even go in to get your own parts, may they burn in hell.

There ya go Matt

If you can get the kit for pretty cheap, all you'll need is an A9L computer from an 89-93 5.0 mustang. You will also have to get a three wire O2 sensor and run a wire from pin 49 on the computer to ground (this is if the stock O2 sensor has 4 wires). Other than that it should be plug and play. Or you could go the "wire it yourself" route using a mustang SEFI harness to pull the needed wiring from.
