Reducing my timing from 22-24° to 16° up top, I'm not making the 480 hp that I did on RRE dynapack with old tune. I'm also running 11.5-11.8 AFR up top now vs 12.7 prior (with clean injectors too). FP HTA71 is really a 460hp turbo on a dynapack. And that's about 420whp on DJ. With old tune, I was ae to hit 118 mph.
24*.. Unless its a 7:1 engine , most of the time you don't see significant gains over a certain amount of timing with most engines. The 4g63 is an old but durable engine.
When you went 118 was that on the same boost, temp or engine health?

This was in August (#4030). Temp was warmer, but I'm not sure on boost. I'll check logs on computer tonight:

Good call Tim!
I didn't realize that the lower WGDC settings with aggressive timing were boosting more than my higher WGDC with no timing. This is log from 12.0s August run (ignore the speed because the default formula is wrong). I see that timing stopped at 20° in 3rd gear on this run.
20 degrees ignition advance seems like a lot from what I've read and come to understand about Evo engines or am I wrong ? Based on the stock Evo 9 timing numbers of ~12 degrees from 6000rpm upwards, even factoring E85 usage it seems like a lot more. But then I've also learned that you can't use blanket ign advance numbers - there are many factors that influence the engine's demand.

Yes. That was my old tune. My current tune peaks at 16 degrees.
I knew those tables or file had the knock sensor adjusted a bit. I mentioned in on post 529.
I think some people adjust the knock tables slightly once they have ruled out false knock on a Dyno or what is considered normal.
The car had 10 degrees more then what most use and didn’t show any knock .
Isnt it possible to turn the knock sensor off in the rom ?
Ouch good catch Bryan! Hey maybe you can chime in on this but im curious how often you are tweaking knock filters? Isn't this a stock motor? If so I cant see why you would ever want or need to tweak the filters.
My built 2.2 with no balance shafts for example still has factory knock filters.
