Manually scale the knock sensor graph so that 0% is the bottom and 25% is the top. In that graph, the spike of 8% appears the same as a spike of 12% because of the auto-ranging scale. Normally auto-ranging is great, but not in this case.

If you ever try to instrument and compare various pressure reading (MAP, pre-intercooler, turbine inlet, pre-cat, etc) then you'll want to do this as well.

Here are my setting for knock input threshold:
I just took a 3rd gear log on wastegate only.

To fix this, go into 'Calculated Fields', 'Fixed Field Min and Max', then 'Add Fixed Field'. Set the min and max on all 4 cylinder knock values to the same levels, and now you can compare them visually.

No, in MegaLogViewer. Normally, MLV looks through the log and sets the top and bottom of the displayed range based upon the highest and lowest values it finds in the log. This means that if cylinder 2 peaks at a value of 80%, but spends most of its time at 40%, then it will look lower than cylinder 3 which peaks at 35%, but spends most of its time at 35%.

That's knock on cyl#2. Not a lot, not very bad, but a tiny bit. You can also see a little on cyl around the 2sec mark. Could be as simple as running the car too lean there (12.4:1 in that range). I would fatten it up to 11.8 and pull 2deg of timing at that boost level. There's also a little puff of knock at 9.413s in the same log.

I just want to say THANK YOU to everyone who has helped/ put up with me so far. I know I ask a lot of questions but I'm learning.
Speaking of questions and putting up with me...in the morning 3 log (all of the above) around the 9sec mark for example there is 12% knock in cyl 4. So when I'm looking at the spark table, the cross section of 5600RPM and 157kpa is 19.8. But in the log it knocks at 17.9*. Soooo.... I'm kinda confused. Do I pull 2* from the 19.8?
