Default Air Fuel Ratio Gauge

I installed the violet Air Fuel Ratio Gauge wire to the B17 O2 sensor signal wire and the gauge reads rich all the time. Does this mean i have a bad 02 sensor or is it the gauge?

It means that AF gauges in our cars are completely useless UNLESS you also install a wideband o2 sensor to go with it.
The stock o2 sensors are not wideband.

So....

To get a proper system that can be used for tuning...which is a REALLY good thing to have....and ditch the bling gauge...which is useless for tuning.....you can expect to pay ~$350 and up.

There are several good ones available.

wait so that leads to question this:

-the defi D-gauges? are they worth it? will they work at all?

i would just like a somewhat accurate to tell me how rich i run at idle through mid throttle.

There is NO gauge that connects to the stock, factory o2 sensors that is anything more than a useless toy, AFAIK.

Defi gauges rock....skip the AF one, though....
