No, it goes lean when there is a misfire or cut.  It goes rich way before then, before then.  

Near the start of the run at 3500RPM you have 2.2ms injector PW at 80kpa MAP and lambda is on target.  Where it starts to misfire at 5800RPM you have 6.8ms inj PW at 133Kpa MAP.  I dont expect the VE changes much between these two points, so for a 65% increase in MAP (air flow) you have a 300% increase in fuel flow.  That doesnt fit with normal logic.

Does the MAP sensor match BAP with the engine off?  

I would at drop the values in the highlighted cells in the fuel table below down to something similar to the 19.3kpa row above them.
