Mass Air Sensor and Housing Identification?

[MikeUrban]

Hey everyone! I'm piecing together my mass air conversion and gt40 top end setup. I was looking around in my basement and I came across this:



It has an f3 part number which designates 80mm. Is there any way I can use this with my car? How do I get everything working together? I have 19# injectors right now

You can use ANY meter that you want so long as it's functional, has decent resolution, and predictable/repeatable results through the CFM range that your motor will be in. You will require a digital tune though. At minimum, the transfer fuction for that meter will need to be interpreted for the EEC.

If that's the meter I think it is; It's a Lincoln/Cobra meter and the curve of the transfer function is not the same as your OEM meter. The curve is not just higher or lower, it's a different curve altogether. Tuning is required.

So one of those SCT tuners or something?

 

[MikeUrban]

I'm so lost haha. Thanks for your help though! Can I just go to bigger injectors or will it still run lean and I'll need a tuner regardless?

If you can get an SCT tuner with the correct transfer function loaded. Dyno-tuning would be the best option if you're going to use that meter. You can also use someth ing like a Quarterhorse or TwEECer/RT. If you're not familiar with digital tuning with these devices, you'll pull your hair out trying to get it to function correctly.

Another option would be to use a Cobra computer (X3Z) and 24 lb injectors (since that computer was designed for that MAF and 24# injectors). My only problem with this setup is that the computer itself is not as widely supported as an A9x.

You still need a tune.

I might have an OEM meter laying around. If one turns up, I'll drop you a PM. At worst, you could use it until you're ready to upgrade.

 

[MikeUrban]

That would be awesome! I'm trying to stay on a budget, so I'd much rather get a stock one than a dyno tune! If you find one I'd love to buy it!

Well do this...

Goto this section of the forum: http://www.stangnet.com/mustang-forums/forums/fox-body-mustang-wtb-trade-cars-parts.304/

and post a Want to Buy ad for a stock, Fox meter. Lots of people have them laying around because they've upgraded. You can probably get one for the cost of shipping.

If I still have the one that I think I have, you can always close the thread.

 

[MikeUrban]

Will do! Thank you again for the help, I really appreciate it.

No worries man. Good luck with your project. What computer are you going to use, by the way?

 

[MikeUrban]

If I can get a stock MAF, I'm going to get a re-man from advanced auto parts by turning in one of my 2.3 computers as a core. For $100 it's worth a shot and I've read good reviews. If not I think I'll do the same for a 93 cobra computer, and grab some 24#s at the junkyard.

What's the full part number? I can't make it out in the pics?

The F3 number on the sensor

 

[mikestang63]

hey not trying to use this as a classified, but if you don't find a stock MAF I have one from my 90 LX that you can have for $20 + ship. Only reason I removed it was to swap on a 95 MAF. Works fine. Think I have the stock bracket to mount it too which I'll throw in.

Where are you located?


Also, back to the computer question. I found an A9P for sale on craigslist for dirt cheap, and I want to use that even though my car is a 5 speed. Any thoughts?

That's a Lincoln Mark 8 MAF meter.

Not really a plug and play application. You'll need a tune to get it to work with your car.

South Florida . Think it's a little too far to drive lol. That MAF won't work without a tune. You can use an auto computer for a stick, but not a stick computer for an auto.

If you want a cheap upgrade, look for a 94-95 gt MAF. It is a plug and play and calibrated for your stock 19lbers. Only thing you need to do either fab up a bracket for the MAF to lower tube or buy one off flea bay. It's a nice little cheap upgrade to a 70mm MAF and the MAF electronics are damn close to the stock one, not causing any driveability issues. PN F2VF-12B579-A2A. They are like $35 to $40 at junkyards.

 

[MikeUrban]

My closest junkyard is like an hour and a half away, so the v8 cars always get cleaned out before I make it down. But I'll definitely look for a 70mm next time I go down there. If not, Mike, I'd be more than happy to buy your MAF for the price you suggested. I'm really getting into the budget build idea haha!

Thanks for the info, I might just try selling it or something.
