Okay, was able to get out tonight and make some adjustments and log.

I kept moving the AFR Enleanment up further and further and the fuel trims started coming down

and the AFR started to move up a bit but not very much

I have the AFR enleanment set at 20 (max according to what it says on the user adjustable table 5-20) and the car is now running about 11.5 AFR

This is better than the high 10's - 11 flat it was running before, but could still used improvement.

So if the AFR enleanment is maxed out what is needed to adjust next the actual AFR target table itself?
