I would turn the Ftrim tables off to start with to keep it simple.  Set your TP, TP delta, MAP and MAP delta lockouts to something suitable. You can look at logs to see what deltas you exceed during transients.   From memory it will work with the deltas set to zero but the MAP and TP lockouts will need a proper value entered.  

I would also suggest you want to set up the error high/low on your lambda analog input so that it fails safe (with ANV6 error value = 0.000) if the sensor fails or a wire falls off etc.

Rate and gain something like below will usually not be far off:
