I would take fuel out at 2500, 4500 and 5000 and add fuel at 7000 then log again to see if it's knocking anywhere.
you want to be ~ 12.5 heading towards 12.0 during spool up (2000-3000) and quickly get to ~ 11.5-11.0 a peak boost ~ 3300
at 4500 and 5000 you're in the 10.9 area, try to bump that up to ~ 11.2
at 7000 you're still going a bit lean, there's no knock but I would get it down to ~ 11.2 and see how it reacts with more timing.
small moves though, nothing drastic, let me know if you have any questions.
p.s. there was no wideband data in your second log, so I did not comment on it.

Everyone here inputted their opinions, but nobody asked the very important question.
What octane gas are you using? That makes a huge difference on what timing and AFR's you want to be running.

He should focus on building a nice lean, mean and "safe" fuel map and then build a timing map optimized for the afr. His timing looks good and I think I even run a couple more degrees than he does with 0 knock with occasional 1's-2's and a 12.0 afr. He can keep adding timing at different areas until it knocks and then back off a degree and the car should run very well. 1's and 2's mean your trying, tuning for 0 knock is just a waste of time.
and cramming timing down a motors throat and adding fuel to compensate so it doesnt knock is just plain barbaric.
By no means am I a "tuner" and i dont tune anyone elses car but my own but so far I have my IX running very strong with minimal mods and is 100% safe.
Here is a link to one of my 3rd gear logs, 23 psi, 93 octane.....its still a work in progress but im getting closer to where i want it to be and its running very strong. I have a tbe, intake, mbc.
