O2 simulator
 

Has anyone bought or used an O2 simulator on their H2 (6 liter). Curious of the results, worth the money?, or just get a new sensor (Bank 1, sensor 1). Thanks

Are you planning on gutting/deleting the cats? If cats are still in place, why get an O2 sim?

My O2 sensor has been out for a year. so if any damage has been done to the cats then i would gut them, run the simulators. I am not an exhaust pro but the cats internally sure seem restrictive to the overall flow. maybe i am wrong and should just go get O2 sensor.

Sims don't last too long, and they're hard to find (since they had to be pulled off the market). Another option is to get the rear O2 sensors programed out.

How do you program them out? what do you use?

Find a guy that can real time tune your truck.
The rear O2sare literally 1 click off/on.

True, but he said bank 1 sensor 1. That's not the rear cat.

Duh. Guess I should have read all of it!
You cant really do a simulator on the front. The computer uses that data for A/F ratio. Sims are always used on the rear. Thats why I assumed rear without reading fully.

I took my cats out. Put flowmaster 40s on. I get cel on. I need o2 simulators? How many?
