i dunno if you want to put 12v to the maf, you might let the smoke out.
idea number 2 is good though

Alright, I tried putting 12V instead of 4.5, still no change. It still doesnt work. I have a few more things to try, but I am starting to look into converting from MAF to speed density, using stock sensors that are already on the engine, like the pressure sensor, TPS, and an RPM input.

I would like to see a straight shot to the TB. Meaning no MAF at all. like using a MAP sensor and converting it's signal to plug into the MAF plug on the car. souds reasonable right? If you can come up with a way to to just get everything out of the way of the air that would be great. how ever you want to do it

Im working on the MAF more today, I thought of another possible reason why it wasn't working.

I guess that some people just need to learn from their own mistakes.

An aftermarket ECU would let you ditch the MAF all together.
Thanks for posting so that others will not waste their time and money with this mod.

the reason you have to replace the afm all the time is becuase ford is too cheap to put a burn off into the ecu...

This may be a stupid question, but what the heck.
Have you bench tested the 2 meters to make sure their voltage output is similar?
A tuner mag did a hotwire conversion on Ford Probe with same plunger style airflow meter. They had to jump through a lot of hoops to make it work. The hotwire set-up they went with provided voltage signals opposite of the factory unit. They then needed a 'black box' to change the aftermarket readings back to 'stock'. After that they also required additional sensors to also take into account the air temp, etc. By the time they were done, the price tag was around an entry level EMS.

This company makes MAF kits. They are just expensive. I have been given a 2000 Mustang GT MAF sensor to try to make this conversion happen. I just haven't had time to devote to it. I am working on getting it to work for a GSL-SE. It wouldn't be hard to get it to work with later models if I can get it to work with a GSL-SE.
It can be done and I am convinced that it would help. I have yet to hear of it hurting performance when properly done.

All we have to do is to make it cheaper for ourselves. For the money that they want for the kit, I would buy a Wolf or work on getting a Haltech. But if we can figure out these circuits, then we could save a lot of money. Think of it this way. Get a MAF from a totaled out Stang, then build a Megasquirt. There is increased fuel and air. On a 1st gen, do the dual leading coil setup for ignition or an MSD. ll are cheaper than Wolf or Haltech, although not as easy or probably as good. But cheaper yes.

People, stop PMing me asking if theres been any progress. There has been none, nor will there be. Unless youre an EE with too much time on your hands, its not worth your time or money.

The second time, I got a fantastic mechanic working on it, and he was honest enough to say that he didn't really know what the problem was because it had some really strange error codes on the ECU, but he reset it, drove it around for reprogramming, and told me to take it back in if I have any more problems.
I have never had a problem with a 2Gen MAF in 13 years. I have no idea why anyone would want to use a Ford MAF, which IMO would be as stupid as replacing the 13B with a Yugo engine. If you want an upgrade that gets rid of the Mazda MAF, then get a Wolf 3D.

I have a 2001 Ford Escape and never had a single problem with my stock MAF... then I upgraded to a 75mm high flow MAF and guess what, still NO problems. Everyone always gives fords such a hard time, but I've owned 2, the escape and a 91 escort... The escort was the ugliest piece of **** ever, was slow as hell, but hey it was a manual, i bought it for 500 bucks and after putting in a k&n and good driving i was getting up to 30MPG and had no issues with it at all. Ford just has a bad rep unfortunately

The rx-7 use and air flow meter, not a mass airflow sensor. The whole idea is to ditch the restrictive, slower acting AFM and replace it with a commonly available MAF.
So far the 5.0 mustang MAF is loooking like the best bet.

Vane Air Meter to be exact but you get the idea. The ford and merkur units are same in construction but are larger=more flow. Turbo coupes are quite plentiful.
