mass air kit

[GT40Mustang]

Does anyone know where i can get a mass air conversion kit? and how hard and long does it take to install?

Best (read: cheapest) is to hit up a junkyard and get one out of an '89-'93 Fox. Other than that, any 3rd party vendor (Summit, etc) or even FRPP.

do you know anyone on this site with a A9P computer or any of the other parts needed for the swap...i already have the harness

They aren't cheap. Best bet, again, is a junkyard or parted out 'Stang.

i dont understand the maf that comes in different sizes ....since i have a 70mm tb and egr plate should i get a 70mm maf? and will the computer just plug in ...cause i see you have to play with 4 wires? can someone clear this up for me

I'm pretty sure the main plug going to the ECU is different but I'm not positive.

do i need the whole wiring harness? ....cause i saw a wiring kit for the conversion and i think it showed ethier 4 or 6 wiring to put in somewhere and to change the computer and that was basicly the swap

I know a guy with an A9P but its set up for 24lb injectors

A9P is just an auto mass air computer and is for 19lbers unless he has a chip in it.

Good how-to should have everything you need right there.

And something alot of you guys should all bookmark...

lots of replacement EFI parts...great tech..etc.

chipped

chipped

Just pop the chip out and it would be ok, but is better off going with a 5spd computer since his car is 5spd already. Unless it was a auto swapped to a 5spd then it would be ok.

wait GT40s car is 5spd?... why would he want an A9P??

Nevermind....I missed that part he was looking for an A9P:smash:

I just assumed he had a 5spd.

That one your friend has would be great then!! Just buy it then sell the chip! What kind of chip is it? SCT? Diablo?

lol why sell the chip gt40 said he has 24s.......

I didn't see anything about 24lbers. Depends what meter the chip was made for...

the car that the a9p and maf were in was an auto lx it had 24s and the a9p tuned for 24s and a c&L MAF 76mm

Did the C&L have the 24lb tube in it? There are 2 different ways to program the chip when you use a calibrated MAF. You can enter the actual transfer function and injector settings, or you can just leave the stock injector settings and scale back the displacement to correct the load by the ratio of the stock and new injectors.

24lb tube in the C&L, and idono how it was tuned, but the guy i bought it from really knew his shit, and probably had it taken to a tuner ... he does alot via computer, soo maybe if was a full stand alone tune? idono... i never asked him..

Ok, he would be safe is he used that exact meter then. The "correct" way is to enter the MAF transfer of the meter then the injector settings to get an OEM like tune. You can use any size calibration meter you want, 24, 30,42 etc as long as you know the transfer function. You can make a close estimation too by using the ratio of the new and old injector size and apply it to the stock transfer function.
