Logging Knock Retard on Mapped Points

[Davem3261]

Is there any way to log knock retard on individual mapped points? I have a couple of spots in mapped point 3-4 that I am seeing knock. I would like to create some sort of histogram so I know exactly where to take out timing. hpt truck.png

You can create a filter in the graph layout to only log when above a percentage of that designated mapped point.

make new graph
parameter spark retard
Filter - new variable - hit the green gear - mapped point you want to use
Column axis RPM - setup the rpm to the same rpm points in your timing table
Row axis load - setup to timing table load values

Thanks for the help. Screenshot 2022-09-17 051745.png
At this point I was between Mapped points 6 and 7. About 8 degrees @ 5500 rpm, 1.8 load. In the tune file those 2 points are at 1.5 deg on MP6 and 2.0 on MP7. I have noticed at lower rpms the load, timing, and mapped points from the log match up with the tune pretty close. Any ideas on why this is?

There's several other factors at play than just the borderline tables, several modifiers such as your OAR is .24, plus the knock sensors were adding timing in the pull.
