I did a couple logs a few days ago and came up with some crazy high knock counts and weird points also. I'll let the charts do the rest of the talking.
Here's one with high knock at the end of a pull
Here's the crazy one. 35 counts of knock at a moderate pull. I wasn't even really laying into it as you can see.
Here's are my ignition maps.
My question is should I make both high and low maps the same so that when they interpolate, it's not as big as a jump? And then when I got a good tune, retard the low map?
