I walked into MAF heaven!

[Mr. Stroker]

OK guys, i went to the junk yard, and i found multiple ford vehicles with MAF. Now heres my question, they was all 302's and the question is.... Will they work on a 351? Also i was worried about the PCM cuz i found a couple of F150s with MAF but a U code trans, and mines not that. So did T birds with the MAF 302's have E4OD's. I was to much in shock to really think straight. Im going to head back this saturday to get prices and shop around a little deeper.

Also will an Auto MAF work on a Manual Trans? And if not, would changing the computer make it work?

Only the trucks/vans came with the E4OD. All the others have the AOD/AODE whatever the newer one is. No the 302 ECU wont work on the 351. That was I was told when I found a F150 with the 302 and Mass air.

Are you talking about the meter or the computer.. or both. Are you doing a MAF swap on your truck?

Also will an Auto MAF work on a Manual Trans?

There's no such thing as an auto or manual MAF meter, only the computers are different.

You were given bad info.. the 302 computer will run a 351 just fine.

Sorry Con, he was asking for me, too. Lol. I was anxious to get some answers.

That's what he was talking about, the computers. Seems to me that an auto computer would work just fine on a manual truck but it might throw some trans codes.

 

[Mr. Stroker]

ok let me getting this straightened out lol i read all that and got confused lol. I Will be doing a MAF conversion on my truck sooner or later. Hopefully sooner.

Ok... first question
1. I heard from a little birdy that cars have AOD's. Even tho! I saw multiple T Birds with 302 HO's and MAF's. Now to me it would only make sense to put a E4OD behind a 302.

2. I read somewhere that a ECU out of a late 80's- early 90's mustang that had a E4OD! would work... I cant remember the source, im thinking fordfuelinjection.com Not 100 percent sure tho.

Ok now that we got it straight that all the wiring from a 302 will work on a 351, im able to get the air box, air tubes that go to the throttle body, along with the 460 air tube, along with all the wiring, and air meter.

Only thing i have to find now is a ECU for a maf truck with an E4OD. There was a couple of vans there, i do recall one of them having a straight 6, but i cant remember what the other one was. Thinking they may have been the older late 80's vans, if thats the case i bet they dont have maf.

Now back to those T birds. Any chances of them having E4OD's? If so then there was at least 6 thunderbirds there with 302's some of them being HO's with MAF. There was also different style intakes, one of the intakes had the throttle body to the passengers side like a normal mustang, some of them went to the passengers side again but had a long spacer that curved towards the front, and some went to the drivers side. So if anyones looking for a HO intake that goes to the drivers side like a lightning, let me know.

Hope u guys can clear this up for me so i know what im looking for when i return to the junkyard.

I really don't care about trans codes being thrown as long as it doesn't affect anything and as long as I get the right computer I shouldn't have an issue anyways.

My plan;

-Get a complete engine harness from a MAF 302 minus the MAF sensor (but I will get the tubing it goes in.
- Get a computer from a MAF 302 'stang as well as the MAF sensor (so as not to upset the MAF that's calibrated with the computer).
- Plug the crap in and hope it works. Lol.

Sound like a good plan?

 

[Mr. Stroker]

OK some info i found on Wikipedia,

1989-1997 "Super Birds"

The Super Coupe was available with a 5-speed Mazda-derived manual transmission as well as Ford's own AOD 4-speed automatic transmission. The base and LX Thunderbirds could only be ordered with the AOD.

In 1994, the Thunderbird received some minor exterior updates and a redesigned interior that featured new sweeping curves on the door panels and dashboard areas, but the most dramatic change was the new 205 hp (153 kW) 4.6L SOHC V8 which replaced the iconic and much-loved 5.0. The 4.6 brought with it an updated electronic control system (EEC-V), and an electronically-controlled 4R70W automatic transmission.

And a 4R70W computer wont work if i have a E4OD right? Even tho they are basically the same transmissions..

Let me know if you find any t-bird 5 spds..

1. I heard from a little birdy that cars have AOD's. Even tho! I saw multiple T Birds with 302 HO's and MAF's. .

All the 302HO cars had AOD trannys.. if they had automatics that is.

2. I read somewhere that a ECU out of a late 80's- early 90's mustang that had a E4OD! would work... I cant remember the source, im thinking fordfuelinjection.com Not 100 percent sure tho..

No such thing. see above.

Only thing i have to find now is a ECU for a maf truck with an E4OD..

Correct. And you'll only find that in the mid '90's E and F series trucks.

You won't get any trans codes with a 5.0 mustang computer, they didn't use electronically controlled trannys in those cars.

My plan;

-Get a complete engine harness from a MAF 302 minus the MAF sensor (but I will get the tubing it goes in.
- Get a computer from a MAF 302 'stang as well as the MAF sensor (so as not to upset the MAF that's calibrated with the computer).
- Plug the crap in and hope it works. Lol.

It'll work.. mine does.. really well.

Great source of information, Con.

I'm hoping to see some gains with my longtubes and my so called 302HO longblock (still haven't had time to look into it).

There were 4r70 MAf trucks At least guy on other site had 1. I can't say personaly. as I never found a truck with any thing other than e4od.


But the 302 Maf setup works fine on 351. I didn't know if to full potential but swaps I helped with 2 guys r more than happy with the 302 ecu and the 351.

You will need engine and engine bay harness . Even if dont want to swap whole harness in you will have all wires needed. Also the Maf air box has a sensor (air temp?) That replaces the one on the intake.

We rewired one truck to use the intake one because guy wanted to use open filter and truck ran worse. He replace stock air box but still not right so we rewired the sensor on air box and was fine, the values must be different or sumtin. Who would have thunk it.

Also if have a manual and have access to auto MAF setup get everything including the trans harness for e4od and the MPLS switch (I'm sure the harness can be to rewire to work without ) Put switch in neutral position . They run just fine according to rFord racing guy I talked to.

This is another one of those little details. Use caution when relocating the air temp sensor with this mod, the computers that use the airbox location are calibrated much differently than those that use the lower intake position. The air in the intake manifold is heated by engine coolant and combustion heat, so it doesn't vary as much as the actual outside air temp. If the sensor is relocated to the airbox with a computer designed for the intake location the motor may run in open loop all the time, performance will be good but milage will be terrible.

I get one right once in while.

These was all U code transmissions.
