I thought so too, but it is only showing the figure that the ECU is trying to maintain (14.71).
It is not showing the figure of the actual AFR from the sensor.
So what I see is
AFR (commanded) = 14.71
AFR (measured) = no data
coz i couldnt find ur posted image not long ago,lol..now i understand.....maybe ur scanner is confused,hahahaha,not so smart like a dyno machine.....ur scanner could be saying dat when the car is warming up,open loop,intake air is not metered and is on open loop,then once the car already moving,finished warming up,closed loop ad,then o2 sensors kicks in and have reading,but til u whack above 3k,it again running open loop,so ur scanner will like ah~~~~i am confused,4get it la,i cannot brain it,juz make it afr reading when the car is running close loop la,

p/s:now after seeing ur image,yea,it oni can shows the afr when ur car is in closed loop,but not open loop,hehehehe
