$6E basic question - is PE added to spark table or part of?
Having trouble understanding the datalog from tunerpro.
The spark adv at ref pulse matches the spark table. Check. And the spark advance at TDC matches the spark table PLUS the base timing. Check.
I don't see any jump for PE. So is PE occuring, and does it add spark ON TOP of the main spark table? If so, I would expect to see the data log with XX more degrees at the various RPM's.
I think I am in PE mode as the AFR drops 10.67 from 14.73.
Sorry if this is a newb question. I've been stewing over these numbers trying to make sense.

NVM. More and more reading ... suggests PE Spark Advance is ADDED to this table. Which explains why the spark numbers in the last two columns are LOW in comparison to the middle of the table.
I have to re-think my timing table a bit.
