This is a common CEL/MIL for rsx equipped with a race header. It would be very helpful if we can have the ability to disable this specific CEL/MIL from coming on. Either by disabling the secondary oxygen sensor (if not harmful to the car) or just telling the ECU to not report this specific error code. Thank you

I don't want to disable obd2, I just want to get rid of this specific MIL
