Hi, recently flashed the 93 basemap on my 19 FK8, and was reading that k retard across multiple cylinders is something to look out for.

The attached log is a 3rd gear WOT pull to redline, after 6500 rpm there is 2 degrees of k retard on cylinder 1/2/3.

Is this an issue or is it within an acceptable range?

From the help file tuning notes: https://www.hondata.com/help/flashpro/fk2_fk2_notes.htm

Knock. Changing the knock retard step table to reduce the knock retard upon a knock event helps to stop large drops in engine power from a single knock event. If there is knock retard after 5000 rpm without any sign of knock, consider changing the knock sensitivity tables.
