Yea I have been checking the part number mostly for compatibility. They seem to be on any 96-99 Ford or Lincoln with v8. The local yards want 35 for a MAF meter so I've turned to eBay mostly. If the housing is a different size how would that affect performance/run ability. I have a 4 inch/90mm?? housing I used on the mustang I had that I can swap to if the housing in a lot smaller

I was thinking 90mm on cobra and lightning.
Carry on.
35 for a maf isn't bad.
It sounds like that ecu is very specifically programmed. I'd start with exactly as it's programmed for and go from there. Bigger meters will sample more air for smaller injectors. So it can have a big effect on the ecu if it's outside of its compensation range.

Yea 35 isn't bad but 20 including shipping with a pigtail is a lot better though. I will probably try both ways and see what runs better. I think 90mm was on the gen 2 Lightnings and 99-04 cobras. I looked up 90mm MAF on eBay and that was what came up with a very different part number

The 90mm was on the 01-04 Lightnings. The 99-00 Lightnings were 80mm, but I think you will still need to re-tune the transfer function , within the ECU, with either one of those, with that ECU.

Could you post that link to the NLOC? Sure would be a big help. Thanks!

Any truth to that or will any MAF meter with the same part # work? I wouldn't think so but I have had to swear at ford engineers over dumb things before.

Well as far as the electronic piece I was going to use the one that was the correct part number for the PCM but put it in the 90mm housing I already have if the housing that I get is really small. I was not going to try to use a different part as my current plan is to run the AKC0 in stock form and change parts accordingly

Another thought/question. I know from another thread about PCM compatibility there was a solenoid pack or diode or something that moved from the E4OD to the PCM in 95. Is there a provision for that in the AKC0 or am I going to have to transplant the one from my current PCM?

That's kinda what I was getting at. If you used the correct sensor, in a larger housing, then the fueling wont be correct. The MAF transfer function was dialed in with with that sensor in an 80mm housing. Not going to hurt anything to try it and see what it does. However, the last time I tried something like that caused the motor to run lean during throttle changes and also a slight tip in lean condition which caused it to stumble a little from a stop.

The sensor measures the amount of air flowing through the tube by sampling a small portion of the air-flow. The amount of air flow flowing through the sensor is determined by the velocity of the air flowing over it. The velocity of the air for a given amount of flow is directly proportional to the diameter of the tube.

If you put a sensor in a bigger (or smaller) housing than it came in, it's calibration will be off, and you will run lean.

Any one out there know if or how I can get a replacement computer for a the out of production Ford Racing Mass Air Conversion kit M-9000-L58?
Is there anyone out there that can fix the computer or "tune" a replacement that will work in place of the AKCO F8TF-12A650-NA? ( think I got that number right) I really haven't played with hot rod parts in a very long time and I'm a bit out of date. I realize that this year of Truck can now be considered Old School......


A friend of mine that passed away last year owned the 1995 Lightning and I'm trying to fix it for his wife.

Usually the only thing that goes bad in these computers are the capacitors. Easy enough fix.
