Raving man is starting to make some sense now,why isnt it happening ?
......A good trick to try with the live data running is to partially block off the inlet to the maf with it disconnected.With the engine idling use a piece of wood or similar to restrict the air going into the maf,this will speed up the air,fooling the maf.You should see the airflow go up and the oxy sensors starting to cycle.Be careful how you do it though.Its a worthwhile test to do as it proves then that the ecu and fuel system can properly go closed loop and fuel the engine correctly.
Now we are getting there.
