anyone know what pinouts are for air/flow signal output…and airflow signal input? its a RB25 ecu

all i can seem to find is #26 Mass air flow sensor ground, and #27 Mass air flow… which is input and outpiut?
I found 2. One here: http://www.innovatemotorsports.com/resources/1993_1998_Nissan_Skyline.php
One Here:
i did find the same one, but i still need to know which is input and output signal…
Humm, I dunno. Moved to NGA to see if anyone else can find it.
I can’t find the right piece of paper that states which is which right now.
BUT, look up Z32. Pin outs are exactly the same +/- a few stupid useless shit between the 2 cars.

The more and more I think about this. Well, there is no 5V input, only output.
Pin 3 = power which is joined with the AAC
Pin 5 = ground IIRC
Pin 4 & 2 go directly to ECM
Pin 1 = non existent.
Again; Pin 2 goes to 27 on ECM. Pin 4 goes to 28.
In essence. You should not even have to re-wire your MAF…??? I did not. Did not even extend the harness.
So I dunno what your after. Hopefully I helped a bit
well basically i have to hook up this SAFC i need to know what colour wires to splice into from the ecu to properly have this safc installed right.

my problem is the car runs like crap with the MAF that i have on the rb25… aparently the safc will fix the issue…
The safc has an input and output wires for the maf signal, but they both tie into the same maf wire… you cut the wire (27) and put the ECU side wire to “maf output” and the harness side of the wire to “maf input”
