Cel light on = it will run the Base factory map.

I am using a VAFC to tune if that makes any difference in your response.

Ok, so any of the cars "learned" fuel trims are not operating properly, effecting just normal driving. Would it effect peak performance?

Mine was so much smoother when I fixed the secondary o2,and the learn returned 
I was on the understanding also as above that its just to test Cat efficiency..
But its not the case and was very noticeable when fixed the cell
the car ran rich with soot on the tail pipes.Not now though
the car will run better = faster through the range.
peak power may not be affected because of throttle position.

Do you need to physically wire the O2 to the plug them or does it literally just plug right up?
So this is the OEM one would it just plug right in?

Even at Autozone they want $300. I am just trying to figure out the difference.

Wow! That is a huge savings. I think I need the secondary which is the downstream.
