I'm hooking up my SAFC II to my red top SR20. I went to the Check Sensor Voltage, it read In-1 and In-2 bothing having volts? The manual says that In-2 is for twin airflow systems (twin turboed).

Is it normal that In-2 has a reading? I double checked my wiring and it seemed good.

while the engine is offIn-1 is at .735In-2 is at .20

I havnt turned the car on yet because I wanted to be sure it was wired correctly first.

lol That's what I'm asking.

In my Sens.Cal, which if I'm understanding right, is determines the number of mafs, I have 1 in and 1 out. Which I thought was supposed to set it to 1 maf.

you should have settings of 6 in and 6 out and 1 in 1 out on the other setting.

1 in 1 out is number of MAFs

6 in 6 out is stock SR MAF reading (you can use the apexi manual for all other MAF numbers).

And the second MAF voltage reading is there because there is always some electrical interferrence. even though .2 Volts is a little high I wouldnt worry about it just make sure your settings are correct.

Yeah the settings are good. It just worried me I was getting a reading from a non existant maf. Thanks!
