O2 sensor meter

[Shawn Fogg]

Howard,

"Since it is in fact the average that the ECU cares about, it would make sense to display the average, not just the instantaneous reading."

On an OBDII car you can watch short term fuel trim which is what the DME is doing right them in response to the O2 sensors feedback. The long term trim is what the trend has been.
