Hi, I hava a 2001 S2000 and wanted to put a rich/lean gauge!!
I wanted to know to which color wire of the oxygen sensor do I need to attach the gauge to!! Any help?? Thanks!!

 

don't waste your time on the rice gauge.

IIRC the o2 sensors on this car are narrowband.

....correct me if I'm wrong.

 

C16 is the Primary O2 Sensor Wire

You stock sensor is narrow band so it is only accurate from about 14.4-15.1. The gauge should not be used for tuning! But it can give you some insight as to what your ECU is doing to correct the A/F ratio. The generally consensus is that these gauges are just for show. If you are really trying to tune your car, look into a wideband.

You should be using shielded wire to make this connection.

 

its an air fuel gauge... not a rich lean gauge... what about stoich?
You know that gauge is next to pointless?

well, it's not the gauge that is useless, it's the narrow band sensor that make the whole thing a light show.

the op got a point, it only shoot from lean to rich and that's about it

 

the need for this gauge presents itself because??
