Right, so pure Alpha-N - then I'd say that's pretty normal - what happens if you bump the fuel a little and get to 14.7:1 without the lambda - the Lambda is probably causing other things to happen, it may be pulling the timing around also - I don't know exactly what goes on inside the ECU as far as what adjustments it'll make from the Lambda...
Out of interest, when it's cold and the Lambda is connected, does it stumble badly? Since it's not open loop, so shouldn't pull the fuel around at all - just run off it's speed-density maps.
