7747 adding too much Spark - very confused

[Skinny Pedal]

Re - Spark Slope: The tool tip to the very parameter you screenshotted says it only starts at 3.600rpm. Is that true or not (some other tool tips are wrong).

Correct, it starts at 3600 where the spark table ends. I was just pointing out all adders you still had active. You would be adding roughly 2 degrees from that after 3600.

So from what I see you are commanding roughly 37 degrees based of MAP. In the first picture you are 3400 rpm and 39 degrees of timing. That should be only PE adder. In the second picture you are over 3600 and 42ish degrees of timing. That should be both adders, PE and slope.
