Need help! Deactivating rear O2 sensor! - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Hi!

I need to deactivate the rear O2 sensor system circuit because I want to install Longtubes. My car is in Mexico and I do not have any possibility to bring the car to a dyno shop because next to my location is no dyno shop. How can I deactivate the rear O2 sensor? Can I use a DialoSport Predator for this?

Simplest way is to plug O2 sims into the wiring harness in place of the sensors. They fool the computer into thinking the sensors are reporting normal readings. They're available at most speed shops.

Might be able to use O2 extenders. Works for the high flow cats to keep the readings within normal rainge.

Thanks for help!

What are O2 sims or O2 extenders?

A "Sim" is a simulator. It plugs into the same place but fools the computer into thinking a real O2 sensor is there.
The Extender is a tube that screws into the spot the O2 sensor goes, then the O2 sensor screws into the top of the extender. It moves the sensor farther out of the exhaust stream and can make it so it doesnt throw codes that might come from headers or high flow cats.

Thanks for your help! Do you know a speed shop in the US that can ship me the part to Mexico?
