Thoughts on my knock?
Up top is a far cry from peak torque and therefore peak cylinder pressure however. I know E85 guys (running an VIII) that have a hard time duplicating the timing a IX can run at almost the same boost on pump. 28psi spike 0* on E85 vs. 4* at 25 on Shell 92. BIG DIFFERENCE.
I block tune so that load cells 220 and 260 have nearly identical numbers in them. I only see 250+ load cells when I crank the boost and thats only done on race gas so I get nearly the same timing with more boost when I run race gas. My overall fuel map looks generic because the cell numbers are the same for the top three loads but it should be known that both boost and fuel conditions are changed when I reach the higher load cells.
(Basic cammed 2003 EVO 8) Here are my timing numbers...at 22psi on 93 octane.
3500 4*
4000 6*
4500 6*
5000 7*
5500 7*
6000 9*
6500 13*
7000 16*
7500 16*

Perhaps I should have clarified. Stock turbo to Stock turbo, Cammed VIII to non cammed IX. E85 is octane of 105 or some I am told, and Shell 92 is well 92. Peak torque timing was provided to show how much more tolerant a IX is than an VIII when the cylinder pressure is high. A cammed VIII should be able to run more high rpm timing than that from the few I have tuned, everything else being equal.

sounds slow
im sure theres even more potential
you know that mitsu loves the evo, cancel the warranty, then charge you 5k for a tranny lol
brings the sticker up to 37 lol
if the 10s make 330 flash, everyone will buy one, break them, the mitsu will eventually break even lol
My latest run:
I really appreciate the help guys. I love learning about this stuff. Is my timing in the 6000RPM range too high. It was showing no knock from 4500 to 6500... then bang, 10 counts.

still way too lean during spoolup and look at 3500... still knocking even though your timing is retarded. I bet the car is very slow like that.
You really need to focus on fixing the low RPM range before you move on to higher RPM

let me give you a few milestones to go after:
2500 12.0:1
2800 11.5:1
3000 11.0:1 and hold that AFR to redline
this is very basic and conservative but it should get you to where you can run a little more timing. then you can fine tune it from there.
