Interesting, Ken - where did you install them?

 

This shows Peter's and my installations in the down pipes near the frame
rail - both get hot enough in 30 secs or so.

We each bought a K&N square-gauge kit and in turn tried running both gauges
at the same time. Eventually we went to a switch as you have.

 

Peter's using both the K&N O2 sensors and I'm using two <$20 Bosch sensors -
all of which seem to work well.
