Ok so I am wondering if there is a monitor for my cat that can be turned off in my tune. The reason for the question is I had my tuner retune my car and he thought that I didn't need to go through emission and turned off my rear 02s. Once I figured it out I went back and he turned then back on and I reinstalled my mil eliminator and with my scanner I could verify rear 02 activity and it now will set the 02 monitor but it will not set the cat monitor and I don't have an egr so I'm using that as my one aloud monitor to not be set. By being able to see that rear activity does that mean I haven't waited long enough or is it possible that the cat monitor is turned off. I have driven this car in all different conditions and there is never any current or pending codes. What's the deal

I wonder if it can be tricked?

Im no cats with a hand held perforance tune..my rear o2s are on ..

no eliminator ...never had issues with cel or drive ability..

its been questioned and I posted video of datalog of rear o2 working.

they say it has to be something the tuner did cause I should have issues this way

I was thinking the same thing but nowhere does it say that it waits for egr to pass before it runs the cat monitor.
I actually found it egr 1-12%
