Hi Ed,
Just read about an extended range O2 sensor in the Turbo Magazine. It is
mentioned in connection with a mixture measuring gadget. Ever heard of that?
could this mean anything for our use? Or is it like any other O2 sensor.
The gadget is offered by INNOVATE MOTORSPORTS.

Here is something that may be of interest to some of you.
Ken and I have exchanged notes on our interest in electronic fuel
monitoring
gadgets for the aircraft rotary. Here is his interesting employment of
the
LOG version of the LED indictor, to give a more linear response curve of
the
O2 sensor. As Ken indicated you are free to use this to build your own or
contact him for a printed circuit board (don't know the cost, but probably
well worth it).
