Hey I just installed my JWT ECU with a Z32 MAF and what's happening is that I'm getting a constant signal of 5 volts from the MAF so the SAFC is reading 100% airflow all the time even when the car is only on the "on" position. Any ideas of what is causing this and how I can resolve it? Also whats the sensor settings that I'm supposed to use on the SAFC, my ECU is tuned to treat the Z32 MAF as stock, I have it set to sensor number 2 in 2 out and sensor cal 1 in 1 out?

Your SAFC settings are wrong. For the number, set it 2 in 5 out if you are running a KA24 or 2 in 6 out if your running a SR. Apexi's webpage has a bunch of downloadable PDF files that help you with the SAFC and their other apps. Hope this helps.

Err, nvm on that last post then.. Didnt read well enough, if your aftermarket ECU is set to read the z32 maf as stock then your safc settings should be fine. Check the wiring to the MAF, make sure you got that right, might have a wire crossed.
