Hi all. After searching quite a bit, I think I'll have to ask :)
In the logs of KTuner there are three labels including AFR.
These are AFR CMD (this should be the targeted AFR, based on the WOT enrichment table - under WOT obviously)
AFR and AFR ADJ. On the later I would need some explanation. Which one is the actual AFR measured by the O2 sensor?

Thank in advance!

OK, great. So AFR is generally very close to the WOT enrichment table under WOT, which makes sense. Can you explain what the AFR ADJ measurement represents?

Thanks a lot in advance!

What does it mean by "Not apply to this platform" ?
It's there for other gens/models but it's not used on this platform (civic 10th gen) ECU's.

Correct. The AFR value is pretty accurate on this vehicle unless the O2 is moved.
What is the right value of good AFR during full throttle?
What are the side effects of running bit richer, say the AFR 9,5-10,5 during full throttle only ?

Thank you Mr. J.R

See the AFR.CMD in the data list for what we're targeting. If you're running richer than that you could use some MAF curve tuning.
AFR.CMD 11.0
And yes it is richer during WOT.
If I leave it like this, what is the side effect? Engine damage?
