If you are looking for a wide band O2 for an EFIS display check this:
http://www.innovatemotorsports.com/products/lc1.php It has a programmable
output with a max of 0-5V. I usually set mine up for AFR 10 to 20 = 0V to 5V. I
have been using these on many engines for over 5 years now and the first one I
bought is still working. For leaded fuel I just change the sensor annually
(about $80). These used sensors have worked fine in unleaded use after that.
These sensors have a porous ceramic that the lead plugs up. A much worse thing
for the sensors is non sensor safe RTV (silicone) sealer, this can kill a
sensor in a matter of a couple hours and seems to affect the sensor long after
it is cured.
Check out Innovates forum for some good info on O2 sensors in general and the
LC-1 in particular.
