those accel enrich values dont look right at all.

you should not set anymore triggers than you have spark outputs.

the rev limiter is set wrong, the base number should be some degree larger than the 'cut' numbers.

the afr target table looks ok, tho it is not enabled.


other than that, yes it does look like the engine is too rich from that datalog.

I would also add that you are probably not making the best use of the 12*12 tables as you have map settings upto 150KPa which will not be seem unless forced induction.
Your AE settings are very high so will probably not be active, which may be why you have ended up with rich settings.
You should also revisit Lambda Sensor Targets as I think you have a few adjustments required there.
