I'll be working through knock sensor wiring and fuel today. Thanks guys!
Another good way to log, which is how I did all my tuning with my Stang, is to just do a 3rd gear pull. Your tune needs to allow you to hold it in 3rd at low rpm though, which my AJP tune does. I do both a WOT run from 0 to 90+mph and a 3rd gear pull from 2500rpm to redline.

Crap, I didn't see this until after I collected logs.
Secondly, I hope I didn't royally eff up my truck. Just after getting in from my last pull, literally two seconds after pulling into my driveway, the engine light started flashing, and the truck started idling really rough. GREAT. No DTC.
I shut off the car, then restarted it, and it cranked for 5 seconds before it started. Still idled rough. Let it run for about 20 seconds, then I got P0302 - Cylinder 2 misfire code, which I believe is the middle cylinder nearest the firewall. I'm going to pull the plug and see if it looks melted.
In the meantime, here are some data logs to look at:
87NoKnockFix is a new baseline run from this morning before I did anything.
87KnockFix is after I taped up the knock sensor wires on the driver's side. No chafing was evident.
91KnockFix is after I added 18.003 gallons of 91 no ethanol BP fuel. I thought the station had 93, but when I got there it was 91. I was 11 miles to E, so I didn't have enough gas to get anywhere else. I burned just shy of 1 gallon of the fresh fuel before taking my data log.
To me, I don't see a substantial difference between the three, and the big jumps in KR seem to coincide with shifting.
