Message Those gauges are not to be used as a tuning tool and they
can only barely be considered to be of use as a warning
gauge.

It relies on a sensor that is already fairly inaccurate and
the build quality of the gauge is not exactly the world's best.

I have seen with my own eyes an autometer a/f gauge show
full rich as the car detonated due to severe lack of fuel. This
is not unheard of, uncommon, or unexpected. When a good
a/f gauge says it's lean, the car is detonating, the injector
pulsewidth is maxed out, and the gauge says it's running rich
you have to wonder....

I would recommend the Greddy a/f gauge (which I believe
comes with its own 5 wire O2), EGTs, or a knock sensor long
before I'd use those.
