It is said:

O2 ERROR BOUNDRY TABLES:
Two tables define the desired O2 sensor upper and lower limits. These
limits are used to decide whether the O2 sensor is either: below, above,
or within the limit window. These are the error boundries. These values
are the actual voltage output of the O2 sensor.

Ron's Q?

What is the range of mv that the GM 02 sensor can function within?

Reason i ask is that if I wish to change "stoich" from 14.7 to say 14.0 I will need to change the R/L Mean the same % amount. To do so I will need to know the ans to that Q.

It will depend upon why the stoich value is being changed. If it is because of E10/E15/Exx then the O2 values don't need to change. At stoich with any fuel the output will be the same (basically 450 mV).

If you just want to run a little richer then stoich, you should be able to get away with +100 mV more in the window tables.
