Default Maf Help!

MAF (f3vf-12b579-aa afh80-01) Searching i found this is from a lincoln mark VII 93-95 with #24 injectors 80mm. The plug connectoris the same as mine 89 lx 5.0 and was originally told it was from a cobra, and just needed to adapt the flange to my air inlet hose. I am going to try and make this work. There is really nothing in the ford maf to tell it injector size, it is in my computer right, so im thinking my #19 stock set-up will be just fine, other than overkill on size of the housing.

Anymore info please, I have read that the computer knows the size of injectors and getting aftermarket mafs and messing with sampling tubes just tries to fool the computer. So i thought getting a cobra maf would work just fine. There is a lot of bad information on maf's and i see it all the time uncorrected, any help is appreciated.

LOL.. you sir, are incorrect

the mark VIII maf will not work properly with the A9* computers in a fox. Look for a 70mm maf from a 94-95 stang... 5.0 and 3.8 will both work

this is actually the correct info.
the 93 cobra computer, along with the 94-95 j4j1 computer were tuned to run 24# injectors. The MAF on a 1994-1995 cobra in interchaneable with a MAF from a 1994-1995 GT. the size of the injectors doesnt matter, the stock "calibration" is in the computer

god damn you people are thick

STOCK MAF'S DONT CONTROL INJECTOR SIZE!!!

aftermarket maf's are tuned to "lie" to the computer so that you can run a larger injector without the computer knowing any different

a 1994-1995 maf from a mustang will work with your 19# injectors, because thats what your computer is tuned to use.. even the Cobra maf... will still work with your stock injectors, because the cobra in tuned with a special computer that has different internal values for the 24# injectors
