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).
