5.0 efi, 91-93 T-bird MAF same as 89-93 Mustang?

[mattt]

The Mustang MAF is the only part I don't yet have for an EFI conversion. I haven't found one that is in good shape or complete. Does the 5.0 Thunderchicken from 91-93 use the same MAF as the 89-93 Mustang? I'm using the Mustang A9_ computer and wiring.

 

[Broncobowsher]

OK I have been searching for the actual tables, having a hard time finding them.
If I remember right, they are different flow calibrations. So you can't mix the MAF and computer unless you reprogram the computer for the thunderchickes MAF.

You may find the curves if you have a binary editor and read files found here http://fordfuelinjection.com/bins/
I'll keep looking for something easier to read.

I'm guessing they are not the same....especially if it is a Mustang HO vs. Thunderbird. After seeing a thunderbird throttle body, it's extremely small and the mustang HO is 55mm. Not sure about a standard output mustang. The biggest issue is what size injectors are in the engine. I think all standard outputs are 14lb/hr (mustang and t-bird) and HO's are 19. So, If the throttle body and injectors are the same, it'll work. If the injectors are the same, it should work. Otherwise, it's not gonna work.

My $0.02.

Thanks Broncobowsher for the help. You da man!

I haven't yet looked at the T-chickens injectors, but it is a 5.0 HO. I think I read somewhere that it is the same 5.0 HO as the 94-95 Mustang 5.0 HO. It has the TB off at a 45 degree angle pointing forward. I guess the injectors would be a good indicator. 19lb'rs are tan/orange color right?

 

[mattt]

I looked at the Thunderchicken's injectors, they look to be the tan/orange 19lb'rs. I looked at the MAF in the T-chicken and it has a part # F1ZF 12B579 AA.
I had an 88 Mustang MAF there to compare the two. They appear to be the same. The part # on the 88 Mustang MAF is E8ZF 12B579 AA. I think this is an 88 only CA Mustang MAF as it has the different connector, more rectangular vs. oval.

I don't know Ford part #'s very well, but I thought the first part of the # designates year, and the 2nd and 3rd parts are the actual part #. If so, it seems like this T-chicken MAF is the same. Anyone know for sure, or have an 89-93 Mustang MAF they could look at the part # on?

Are MAF's a "works or no work part?" Or do they age and wear say how O2 sensors do? Im thinking of grabbing the 88 Mustang MAF even though it doesn't have the same connector as my harness, and I might grab the T-chicken MAF too.

On a side note, I ran across a Mustang computer out of this 88 MAF car that I've never seen before....8LG. I can't find any info on this ECU, but it definitely is 8LG, and it's definitely an 88 CA Mustang MAF car.

I didn't know that many interchanged! Have to take this list to the U-pull yard next time I go!

Yeah that was a nice surprise. The Taurus, Sable and V6 t-birds should be a dime a dozen.

 

[mattt]

Is your interchange list saying that all those vehicles have the same EXACT MAF sensor and housing? If so, I had no idea that many cars ran the same 55mm MAF. Is there a way to test a MAF as buying this used is questionable.

P.S. Where were you able to pull that kind of interchange info? That sort of interchange info would be invaluable.

Probably from Hollanders Interchange Manuals?

I need to pick up one of those manuals someday.

There are a few things it doesn't cover. 4.0 V6 SOHC power steering pump will fit an Explorer but doesn't show in the interchange manual. The inlet nipple has a different bend in it for example.

I have access to an interchange book. Those MAF sensors should all be interchangable. If you were to walk into most any junk yard and ask for one, you would likely get something on that list. I would not hesitate to interchange any of them. Sometimes there are notes about slight differences and minor required mods for interchange. In this case, there were no notes.

As for buying used..... I couldn't afford to go wheelin otherwise. Personally, I'd rather use a used OEM part than a new aftermarket part anyway. There's something to be said for OEM quality and reliability. I get a chuckle out of people that think every part on a car is suddenly bad when it enters the junkyard. The EB crowd seems to be a little sensitive in that department.

 

[mattt]

Thanks again Nobody for the cross reference info. Its surprising that a 6 cylinder Taurus would have the same MAF size/spec as a 5.0 HO Mustang. I hear you on affording this hobby with junkyard stuff, that's how I do it too.

Anyone know the formula to decipher Ford part #'s?

 

[Broncobowsher]

Anyone know the formula to decipher Ford part #'s?

The first part is a date reference, car line, and part of the vehicle.
Middle part is roughly the blueprint number.
Last part is the revision to that number.

For the most part the only useful info is the revision date. E7 heads are heads that were revised in '87

If it makes you feel any more comfortable about the interchange, you can look up a couple of the vehicles at www.napaonline.com . I did 92 5.0L T-Bird, and 92 V6(232) Taurus. Both call for the same part number.

Mass Air Flow (MAF) Sensor - New NEC

I'm not really all that surprised about the interchange. The sensors are merely sensing flow. Much like a TFI module has a set function. There are only 2, Black and Gray. Another way to think about it is a thermometer. Some use mercury, some use a bi-metalic metal strip, etc. All report the same temperature. Your computer just needs to know specific values to calucate air/fuel mixture.

I checked Napa for a 93 Mustang GT 5.0, and it shows a few different MAF's. One of them being the one that Nobody shows above. Wonder what the differences are between the MAF69502, MAF69500, & MAF69509...info from Napa site below.

I have a meter I got from a 91 5.0 i Believe. I'll put it in a box and if you pay shipping you can have it!!!! I was going to throw it away!

In '93 there is also the Cobra. That used a different MAF/computer/injectors. I'll bet that is the third one.

That is correct. This is the interchange for a 93 Cobra
