Hi folks, I have a 98 5.0 from an explorer and wanted to know if the stock MAF would work with an a9p EEC? I would think the output voltage would be the same. I am using the stock 19 lb. injectors. Any help would be greatly appreciated.

Thanks Gdub.

Factory MAF meters are not calibrated to injector sizes (that's done in the EEC processor) and they usually have differnt transfer functions. I can guarantee that the Explorer MAF won't work with an A9P EEC. For one the A9P is an EEC-IV processor where as the 5.0 Explorers are all EEC-V processor equipped.

So what do you think would be the best thing to look for?

Besides the stock Mustang 55mm units the following 70mm units will work with an A9P. Before I got my 73mm C&L MAF and 24lb injectors I used a 70mm MAF from a 1994 Lincoln Town Car. You need the MAF sensor from one of the Following Ford vehicles:

1995-94 Mustang 3.8L F2VF-12B579-A2A,
1994-92 Crown Victoria 4.6L F2VF-12B579-A2A,
1995-94 Mustang, Mustang Cobra 5.0L F2VF-12B579-A2A,
1994-92 Town Car 4.6L F2VF-12B579-A2A,
1994-92 Grand Marquis 4.6L F2VF-12B579-A2A

Now these sensors all have a and that has to be ground down to use the stock air intake tubing. I ended up using the F2VF sensor in a 94-95 Thunderbird MAF housing, since it was 70mm and had the exact same internal measurements as the Town car housing. It was able to bolt right into place like a a factory meter instead of having to have the ground off first.

Thanks ThunderJet, Off to the yard to see what I can find.

It's an Explorer engine, with an Explorer MAF. What would happen if you tried to use an Explorer EEC?

Well the Explorer uses EEC-V with no distributor. A Fox Thunderbird/Cougar/Mustang/Mark VII uses EEC-IV with a distributor. You would have to rewire the whole car to use an Explorer computer.

With an A9P/A9L Mustang EEC-IV computer you have to either use the stock MAF that came with an 89-93 Mustang, one of the MAF meters I listed above, or an aftermarket MAF calibrated for the correct injector size (C&L, ProM). YOU CAN NOT USE ANY OTHER MAF BESIDES THESE WITH AN A9L/A9P COMPUTER. Don't try it. It won't work. The MAF meters that I just talked about are the only ones that will work. It's been proven by thousands of Mustang guys. Factory MAF meters are not "calibrated" to an injector size like aftermarket MAF meters. The injector calibration is done in the computer. What a calibrated aftermarket MAF does is change the amount of air flowing over the MAF element. This allows the computer to fire larger injectors than the stock 19lb ones. The factory MAF meters don't do that. If you look up the interchange for a stock 89-93 5.0 Mustang MAF you'll find that it was also used in 3.8 Continentals/Taurus/Sable applications as well. They used 14lb injectors from the factory. The factory MAFs are not calibrated to an injector size.

Ya, I wouldn't want to rewire a whole car to use an Explorer EEC. :)

good thread! on maf meter compatability, i will need this later.

also if your gonna run the A9P/A9L ecu's it fires the injectors on the H.O. firing order, the factory bird cam is on the non H.O. firing order or standard 302 firing order..

Can you run a A9P or A9L with an AOD? Will they work the same?

The auto ECU puts a bit more timing in in the lower RPM's. With a car having a torque converter, it's a welcome addition.
