 Yeah .. I do .. how about internal BOSCH memos and cal docs on their LSM-11
 sensor ..

 Put the dammed electrochemical textbooks away .. this is the REAL world, not
 the bloody lab!!

 If you have a (basically) known composition fuel (gasoline, known C/H ratio) you
 can then linearize the sensor .. even better, the LSM-11 sensor is a carefully
 built sensor which is constant from sensor to sensor .. 

 If it's good enough for Bosch Motorsport, it had BETTER be good enough for you!
