MAF swap

SWEET2KSTANG · September 14th, 2009, 01:41 PM

if i were to change my stock MAF to the later MAF style, will the car run without a tune? i would just be putting a stock MAF sensor and housing in place with stock injectors so i can do the initial start and intitial drive.

dcook_14 · September 14th, 2009, 09:32 PM

It might run, but I doubt that it would run well. The later style MAFs are slot style and ours are not. Is there a size difference? I have a 90mm LMAF I might want to sell...

if by later you mean '02 & up (integrated AIT sensor) MAF, don't waiste your time, I just spent about 2 week's with wiring diagram's/ etc., it's not worth the hastle.

SWEET2KSTANG · September 14th, 2009, 09:39 PM

i will be going to a larger MAF when i go to dynotune the car. i just need to get my cat to start and run after i get it back together. i will be starting it on a stock 80mm MAF, get the slot style meter, but didnt know if it would be calibrated close or not. the stock gt's were all 19lb injector, i will start the car on the stock inhectors as well. i will probably go to a C&L 95mm MAF unless i just run across a 90mm for cheap.

how much are the C&L maf's?

there is an adapter harness for the swap. the stock wiring to maf is used, and the IAT is still used as it is now. i will need to go to a larger MAF for my build, plus it will be nice to get away from the sample tube set up as well.

SWEET2KSTANG · September 14th, 2009, 09:48 PM

the 90mm MAF's are able to be gotten cheap, but i think i have plans later for a bigger build

GTsetGO · September 14th, 2009, 09:49 PM

fine. be that way.

what are the plans? PM away.

SWEET2KSTANG · September 14th, 2009, 09:58 PM

well......... i might.

smccoy916 · September 14th, 2009, 10:11 PM

I went with the HPX slot Maf. Really easy to tune compared to others I've played with but I am FI.

SWEET2KSTANG · September 14th, 2009, 10:13 PM

the other maf i am looking into is the dbx, but not sure. i have to change a few things to the build as of right now, so i have to go back over the set up and do some homework.
