Wow! TunerPro showed Knock Counts like the Energizer Bunny! They just kept going and going! Not sure what you were doing in the log at 5 MPH for a long time at 2400 RPM, but knock counts never stopped at that point!
When I get back I'll give a better look over of the log.

Speedo is way off. Like 70mph shows as 9 or 10mph. 55 mph shows as 5mph.
Edit- Looks like the knocks didn't go crazy until after I left gas station. Something must have wiggled out. The drive to the gas station was fine, but not after, and the truck stayed idling while I was there.

Only got breakfast there, no gas
In tunerpro RT, theres 9 tables for knock, which one do i use? running sample count?
and theres 9 tables for BLM history. use running average?
Also i use 93 octane, and i thought my spark advance was semi conservative.
Time: 6:30-6:50pm central time
Temperature: 75 fehrenheit
Humidity:40 percent
a darn good time to log i recon.(i dont know what this green guys doin but i like it...)
Heres a much better log than this morning.
edit---And because of the knock i went back to ARJT from ASDU(didnt help)and the knocks showed up in that area before and i lowered the spark and it went away. i think the warmer day and the actually being warmed up all the way brought it back. so i lowered it a little more for this log. It may even be somehting rattling at that rpm vibration? maybe not

So you had no gas after breakfast? That's good right?
You were plenty warmed up and knock counts shouldn't have started... (well maybe if you left idling and got hot) but should not have continued. I'm curious now and have to look at that part of log and see what happened.

This ECM is hard to use knock counts as a tool. Use Most recent Sample and when you see a knock count increase, the actual number means nothing, when it is increasing does mean something/knock counts! Pause the data log and use key controls to go 1 frame forward at a time. Shift + [ for one step back and Shift + ] for one step forward. Your's was pretty obvious as it just kept going!
If you use the method I described along with Data Tracing and the SPark Advance table open you will see the exact area that is causing the knock counts. It usually takes 3-4 degrees less in that area to safely remove knock counts. There is a borderline where to much spark advance is not helping power, but also not causing knock counts. It does cause heat in piston and stress on wrist pin and rod bearing along with oil temperature rise!

nope no gas after breakfast
ha fuel that turns into gas......related indeed (had to get in on this on the ground laughter)
P.s. thanks mark and dave for making me get RT thats amazing I like the monitors area ahahaha GREAT Stuff, albeit a little confusing at first. you can really see some stuff. much better than visualizing winaldl text. definitely going to donate the 39 doll hairs its well worth it, plus itll get rid of that 10 second delay. i's just a little skeptical at first
I think I'm only advanced around 26-30 degrees with that 2400 cruising rpm knock, that couldn't be to high, could it
Of the MAP AE and TPS AE which one fuels the initial pedal smash and which one carries through as you keep it floored?
I'm still not up to helping much past AE !!
TPS AE is a short blast while throttle blades open.
MAP AE is the longer AE to finish the transition...
