FAQ:

Q: Should I add a spacer to my O2 sensor?

A: Adding the spacer introduces a dead-spot where exhaust gas doesn’t flow across the O2 sensor as it would when the O2 sensor is installed in its proper location.

Q: What is the purpose of the O2 spacer and isolator?

A: The primary use of the spacer and or isolator is to take your O2 sensor out of the exhaust stream so that your O2 sensor senses less oxygen in the exhaust pipe. For use with a good running Hydrogen/Oxygen Cell that will produce more water H2O, and oxygen in the exhaust pipe.

Q: Is it possible to adjust the O2 sensor without the ECU?

A: No, it is not possible. The ECU monitors your O2 sensor to know how it needs to adjust its fueling, this can be done in different ways depending on what type of O2 sensor and how the ECU manages its fuel.

Q: Do fuel injection systems use O2 sensors to adjust AFR?

A: There do exist fuel-injection control systems which actively employ the post-cat O2 sensors for adjusting the air-fuel ratio (AFR). The topic was discussed to death on the E39 M5 forum that I used to frequent, and was the primary reason why removing the catalytic converter on the M5 had an awful impact on performance (and emissions).
