o2 sensor voltage reading on Apexi S-AFC
Just read an interesting article on the installation of an S-AFC on a Supra, where they used the (normally unused) blue wire on the AFC...has anyone doen this on an FD3S ?

This allows you to read Oxygen Sensor Voltage on the AFC display. On the wiring harness for the AFC the blue wire is not normally used. The blue wire is meant for the second Mass Air Flow Meter on a Nissan 300ZX. You will connect this wire to the O2 sensor wire right at the ECU. To read the O2 sensor voltage, scroll down to and select the "etc." menu. Select the "Sensor Check". Of the three readings, O2 voltage will be the middle one (#2).
