I'd get a wideband so I wouldn't have to guess what's going on with the tune. It's really hard to diagnose a log without AFRs...

As a general rule, a 1-count knock is generally not consided real knock, as it can be mechanical noise, valve train, etc. But for me personally, I consider a string of 1-counts, or anything more than a 1-count to be real knock.

The TXS Tuner Pro is pretty neat cause it comes with a head-phone jack so you can listen for knock much better. The TXS Tuner Reg is what I have, and it is great for logging etc, but doesn't have all the bells & whistles that the Pro has...

This last log snippette looks pretty severe:

6747 102 +4.8 30 +16.2 rich 00000
6734 102 +5.0 30 +16.3 rich 00000
6747 010 +4.1 30 +17.0 rich 00000
6485 000 -3.8 10 ECU. rich 00000
6161 000 -7.5 10 ECU. rich 00000
6093 000 -8.6 10 ECU. rich 00000
5602 052 -9.1 00 ECU. rich 00000
4761 096 -2.8 00 ECU. rich 00000
4923 105 +1.6 10 +9.4 rich 00026
4930 104 +2.5 20 +7.5 rich 00026
4930 104 +3.3 20 +7.6 rich 00000
5065 105 +3.9 30 +15.5 rich 00000

This looks like a clear case of shift knock to me. This can generally be cleaned up by adding fuel to the 10% column in that rpm range.

A 26 knock count is pretty damn severe. Like engine-damaging severe. If I were you, I would get this fixed asap before you start snapping/ folding rods, hammering rod bearings, or chipping piston ring lands. Even shift-knock can be detrimental to an engine.

As for the first log with the string of 4-count and 6-count knocks... Since you don't have a wideband, I'd just add a little fuel and/or back off the timing a bit and see if that helps. If not, you probably have carbon build up or have internal damage.

Edit: Maybe you could also try a step colder set of plugs.
