For when the truck is in run, while changing tunes and what not, I can turn the controller off, the switch actually runs to the controller. With the AEM the guage was the controller. Also, this doesn't apply to me very much do to the climate, if it's really humid, where there's more condensation in the exhaust before start up, I could leave it off, then start the truck allowing any moisture to burn off before the ceramic sensor heats up.
I did a lot of research on why wideband sensors fail easily. Specifically the Bosch. You never want to have the engine running while the sensor is off, and you never want to have the sensor on, while it's not running. Also if there is moisture/ condensation on the sensor before it heats up it could break it. The ceramic sensor is very small and thin.
One of the more helpful articles I read:
Bosch is the world's leading manufacturer of exhaust gas oxygen sensors. Their LSU range of wide-band sensors has been widely adopted by the OEMs and can be found on a huge number of production vehicles to accurately measure Lambda or the air/fuel ratio (AFR) in the exhaust system. Their common...
