Default ignition base timing A vs B

hello everybody!

I was working on my ecu ignition table to get rid of some flkc and fbkc. everything is clear, I have done it. I almost do not see knock correction in log files. but one qqestion is diging my mind: what is difference between A and B tables? I know what base A timing does, but for what reason is there second B table? for low octane fuel? if it's for low octane fuel, I should retard values there even more to be safe... (I always use RON98)

You are talking about open source software. You'll want to post in the open source sub-forum.
