Z32 Maf Upgrade
Upgarding to a larger Z32 air flow meter!
For those looking to enhance the BHP to over 300 horses, it's a good idea to upgrade their air flow meter to a larger unit like the one from Z32 (300ZX). The basic stock airflow meter is good up to 300BHP anyway and the Z32 is useable up to at least 500BHP.
The Z32 have a 80mm diameter surface area opening for the compressor to suck the air in. Wwiring wise is pretty straight forward if you have a steady hand and knows how to use a solding tip.
Of coz , along with bigger injectors and turbo, the larger unit definitely sees its usefulness.
You will need either an Apexi SAFC or a fully programmable ECU to control this. Using the larger air flow meter without any supoorting means will give your S13 and erratic idle and power.

Wire the MAFS in like the diagram below.
The 12V+ wire on the CA18 is black with a white stripe.The negative(-) is all black.
The signal wire is like orange . The Z32 have two ground. Just twist the two ground together and connect to the negative.
Then on the S-AFC, go into the SENSOR TYPE menu and select HOT WIRE. After that, calibrate it (email me for calibration).
That's it! It should run perfectly, just make sure you have the MAFS hooked up properly.
