MAF TB CAI qustion...
I recently came across amaf from an expedition it seems to be 90mm. Can this work for a 94 gt ... if not can i just use the housing and put my old sensor on it?
I want to get a 75mm throttle body, use this maf and find a cai that will accomodate the tubing from fenderwell to tb. do they sell such a cai kit???

and the other question was they are fenderwell kits but... they come for the stock tb wich has a smaller bolt patter than the 90mm one ... all the ads dont specify what size tb or maf and I dont think its a one size fits all deal ....

No, that MAF will not work if you just bolt it up. Without reprogramming the Mass Air Transfer function in your Mustangs ECM, with the specs from the Expedition's MAF, it wont know how much air is coming into your engine. You cannot just change things like MAF's and injectors without reprogramming the computer.Even the so called "calibrated" MAF's you can buy from C&L and Pro M aren't the best way and can stillcancause issues on occassion. As for fitting a larger MAF, most quality CAI kits come with universal adaptors to fit the various size and types of MAF's.

I thought it knows how much air is passing by the voltage it sends to the computer, like a tps, the way i see it nothing changes just air flows easier rather than being restricted through a 70mm maf

Yep, yourkinda right, butyour cars computerhas been "programmed" from the factory to know howmuch air is passing through the "stock" MAFat acertain voltage signal. The problem comes when you install a better flowing MAF and dont re-program the computer. Lets sayyour computer is "programmed" to know that the "stock" MAF is flowing 4.5 lbs. per minute of air when its sending a 2 volt signal. Now you install the Larger Expedition MAF which flows 6.5 lbs per minute of air while sendingyour computer that same 2 volt signal. The problem is no one re-programmed the computer, which meansit still thinks that2 volt signalequals 4.5 lbs. per minute of air flowing through the MAF.As you can imagine thiswould cause all kinds performance and drivability issues, as the engine is actually taking in more air than than the computer thinks it is.This is one of the reasons companies like C&L and PRO M make specially calibrated MAF's to fool the computers stock programming, which IMO is still a half assed way around doing it right, but dont get me started...lol...thats a story for another day.
