Hello all i installed a Air Fuel gauge in a pillar pod. i Tapped into the 02 sensor on the header tried each wire with no luck in a receiving a reading even after i let the car warm up. AM I SUPPOSED TO TAP into the O2 on the S/downpipe instead?

Has anyone done a DIY Air Fuel Gauge on a SCION tC? any info pointers or help is greatly appreciated!

Thanks Everyone!

 

what A/F do you have?

 

You will need an O2 sender for the gauge that welds into your S- pipe... It will not work with the factory O2's.

 

gauges like the AEM which i've had before provide a o2 sensor... you just have to weld a bung to u'r S-pipe. All you would need then is a power supply to power up the gauge

 

if he has a narrowband afr gauge, he can plug that into his stock o2 sensor... but narrowband gauges dont tell you anything, they just flash a bunch of pretty lights

 

Thanks for the feedback everyone! soo either way i connect to the S pipe it is a narrowband sensor and i can agree its nothing but some flashy lights lol ill have to look into the AEM stuff in near future.



AS FOR THE COLOR OF THE WIRE I TAP INTO does anyone know?

I have 2006 Scion tC and the harness i believe has 2 black 1 blue 1 white (on headers)


Any Pointers on what color the wire might be on Spipe for me to connect, for the narrowband sensor?

Thanks!

 

FOR ANYONE THAT CARES IT IS THE BLACK WIRE On The DOWNPIPE/Spipe i figured this out after much trial and error! haha

enjoy
