i connected the blue wire on my safc to the o2 sensor by the ecu....but i dont know what setting to use to monitor it....right now im monitoring rpm and throttle (via pressure sensor)...what do i need to select to monitor the o2 sensor

 

go back to the original main menu, go to etc., then go to sensor check. I believe it will be the second voltage.

 

What you can read O2 voltage with the SAFC?

 

Just reading the voltage from the stock narrowband o2 sensor. I wouldn't reccomend tuning by it, get a wideband. They're cheap enough these days.

 

true

 

Hello,

Do you just tap the blue wirie from the SAFC to the black O2 wire from the harness?

Thanks.

 

correct, just tap into the o2 wire that's coming into the ecu. I don't recall which pin it is offhand.

www.iluvmyrx7.com has the FSM, look in there.

 

What is the purpose of this mod? I didn't know that the SAFC can monitor O2 readings. Please enlighten me on this mod.
