Looking at my logs, My AFR numbers look good.  Not jumping around, and steady.  But the AFR Trim number is normally in the 25 range, but sometimes up to the mid 50's.  During the time the AFR Learn is 0 or very close to it.

But when the AFR Trim goes down to the low teens or the single digits, the AFR Learn goes up into the positive mid to high teens.

Is there is normal good set of numbers for these two indicators?  My AFR numbers always look good.
