I was wondering if a a/f guage would work on a non obd setup. the o2 sensors are 1wire o2's. Would I just tap into the one wire or what. I dont know. any input would be great.

 

someone has to know?????

 

shouldn't hurt to try?

 

I guess, but I was thinking someone might know already. I know its not the most accurate but I would still like to check my vitals before I go beating on my NA motor, and before I make it to the dyno.

 

I thought that on some(?) of the 1-wire sensors, the wire was shielded. So just be aware when you cut into that wire.

 

find the ecu pinouts and tap it into the o2 wire going into the ecu

 

Works on mine with just one wire, like mentioned above. Just tap into there are anywhere past the connection where it hooks into the wiring harness...

 

What makes you think OBDII is so special?!? All it is is an O2 sensor with a heater attached. The only difference is that non-OBD cars don't have the heater =P. Just attach the air/fuel ratio gauge to the one wire, somewhere near the ECU.

I personally have the O2 sensor tapped into the output from a DPST switch, and each of the poles hooked up to an O2 sensor output on a dual-O2 sensor B16A. So I can toggle between the O2 sensor outputs on each bank of cylinders. It's kind of interesting to flip back and forth sometimes .
