Let's see your fully tuned timing maps

lol ive been there. This thread has greatly helped me grasp my timing curve. I still feel Im missing a few areas and my ramping timing up at low loads may seem steep, however I dont get knock. I may be leaving some on the table in some areas and Im guilty of the "implying smoothness where its not present"...
a majority of the timing values in the low rpm spool are determine by eliminating knock so I was blending that in with the shift knock and eliminating the presence of that. Timing is almost linear at spool from higher rpm, vs lower rpm is curved

I have been playing with the tune trying to get things squared away. Thought things were doing relatively well. Last night at the track I was getting some knock in 3rd and 4th. Ill attach the log and my ignition map. Let me know what you guys think. I know there are many of you who have a hell of alot more experience than I do. Current mods, Ets 4" core with ets upper pipe/ evo 9 dv, and buschur lower, stock viii turbo, intake (no idea whos), turbo back (no idea whos), grimmspeed 3 port, wally 255, aem uego, all of this is on pumpee 91.

Thanks for the input.
My wife is driving the car this week so I will do some tweaks when I have the car again.
Does anybody know of a specific parameter that would affect knock @ right around 5500 rpm?
I sometimes get knock counts up to about 8 out of nowhere @ 5500 rpm.
No afr spike or timing jump. Not sure what else to consider.
That is one reason my higher rpm timing is a little lower and why I'm going to try cooler spark plugs.
Thanks again.

opinions on this one...where can I improve it. I have also included the VD. For some reason my VD numbers are inflated. I picked level ground, VD numbers change around 10 hp from smoothing 1 to 6, and I consistently get these numbers run after run, and my gearing is the same as the Evo 9 RS(5 speed). Anyways if anything a good reference. (note: I have added a bit of fuel in the 3750-4500 range as you see its a bit lean, and the logs only show 1 count of knock at 3200 RPM)
-JDM Evo 7
-Running 93-95 octane
-stock turbo w/10.5 hotside
-GSC S1 cams
-ETS 3.8" garret intercooler w/upper and lower intercooler pipping
-MAP o2 eliminator downpipe and AMS exhaust
-boost peaks at 29 psi from 3600-5000 RPM, and falls down to 25 psi @ 7000

That knock looks to be NLTS-induced to me. Try to smooth out your timing change at high rpm, low-mid 100's load. For example, at 6500 rpm and between 160 and 180 load, you go from 21 to 14 degrees. Smooth that out to a change of no more than 2 degrees and see if it's better (lower the timing to the left of the 14, don't touch the right side, it looks alright.)

You are the man. Ill play with it tonight. I completely thought past nlts being a contributing factor... I think I read somewhere you said you were running -10* on your launch map? How much boost are you able to build? I noticed I was only getting about 8-9psi at the line at about 5800 rpms with timing around like 5*.

What's with the sudden drop to -10 at high rpm and again at high load?? Map needs some work in other areas where timing goes in the wrong direction.
That looks like a pretty good map to me. Don't know what could be inflating the numbers, do you have the weight entered in correctly?
