Think it all depends how it's mapped but think stock works of the narrow band sensor in the exhaust elbow and working in a closed loop with the ecu and targets 14.7 afr in the idle and low load areas of the map if that makes sense.
I am by no means no expert but think that how it works
Update: took the car to mappers yesterday to check if the AFR readings are correct or not. Car is running correctly. Everything is as it should be. Seems the sensor is possibly kaput. Got a new one so will know for sure pretty soon.
