To get usable AFR data using a wide band system you will need the air injection disabled I would think.

I have wondered what the factory procedure is for setting CO. Is the air injection pump off at idle?

Is it to be disconnected for setting CO.

Maybe the factory CO setting takes into account the effect of the air injection system being active.

I do not know.

That is another reason for removing said system I suspect.
