Converting to Z32 MAF in a STI 5

[prelude_b16a]

Hi guys, have anyone of u guys successfully converted to a Z32 airflow?

I'm running a power fc ecu, and im pretty sure the wiring for the z32 maf to my cars wiring harness is correct, but the check light is on and the car is very rich. i tried to calibrate the voltage settings on the power fc vg30 airflow menu but still no luck...

if anyone can give me any advice id really appreciate it,

thanks
