Tuning timing maps.
If adjusting timing has no affect on your knock counts then odds are its false knock. You can log knock_base and knock_adc_processed in evoscan and then graph them after a run. If the processed line is constantly butting its head on the knock base line then its gonna register as knock although its probably just noise and you can try bumping up the knock mulitplier in that range. If its a sharp spike poking up through the knock base then odds are good its real.
So, I take it you didn't read the thread? Look, Ive been communicating with you via email and pm. Im trying to help you and get people to help you. I dont know if its a language barrier that makes it cone off as if youre not trying to learn. Me personally, if im going to continue, im going to need you to do some homework. I started helping to give you a chance to help the turbo auto community, but if youre just trying to ride on coat tails im not down with that. If you’re not going to attempt to try and help the community im through.
To adjust airflow you want to log air flow hz and adjust accordingly.

I've been spending more time focusing on timing lately. What I've found is that timing should be somewhere between the stock values in the stock rom and the evo values. The car hates the stock values because it's too little in the 80-100 range. The car hates the evo values, it's too much, knock all up in the 60-100 range. There is a happy medium but I can't find it. I also tried corelating the timing at, say 3000 rpm, in both roms and calculating out a conversion factor. It didn't work, but it was half way close.
The 2 engines are so similar and yet so different, I just can't get it perfect. Anyway, I'll post my current timing again just so people can see, but it's not idea by anymeans.

I played around with my spoolup timing awhile back to get faster spool, then later realized my wastegate flapper was still staying open a little during spool up causing my slightly slower spool. So now with the wastegate closed during spoolup combined with my earlier efforts with the timing map my turbo spools faster than it ever has. I am actually hitting more boost now too since I dont want to adjust the wga rod (i've had enough of messing with it for awhile lol). My gauge reads close to 16 so since my gauge reads around 1-2 psi less than actual I am hitting 17-18 psi :-). Spool up is so loud its awesome!!! I rev it out to redline but not as often as before Im nervous to blow something. Then again I dont have to hold it WOT anymore it pulls plenty at 1/2 throttle
I have trouble seeing knocksum counts of 8, not during spoolup but if I go from cruising at a steady speed and then accelerate. It doesn't have to be mashing on the gas, it is mashing or just as slow as possible adding accel and the light comes on no matter what. It's only when the car is hot, not just operating temp hot, but after I've been driving on the highway for a while too.
I don't have the EGR enabled, that's what I thought it was first. If I just let the car slow down, engine brake style, it doesn't knock (light blink). Do any of you have that behaivor or know if it might be timing related or something else? I think it might be that by decel and coasting it is cooling the EGT, so maybe it is real knock because the exhaust is just too hot. Also, lets post timing maps, I want to see what you guys are currently using.

Do you still have your knock values all stock? I had issues with knocking in that same general area although my egr is still enabled. It wasnt a for sure knock everytime it was rather hit and miss but whenever it would knock it was in that general area. I firmly believe that it is not actually knock but more has to due with the difference in engine harmonics between the evo 4G63 and 4G94 (for those running evo rom). I never seemed to have an issue with this when I still ran lancer rom. Ever since Aaron changed my knock multipiers to 24 across the board random knock has not been an issue.

If yours is as persistent as you say and you have moved the timing every which way with no change in knock counts (same issues as I had) chances are its just engine noise that the evo rom is not calibrated for. Mine are all set at 24 why not try moving yours up to 20 and see what happens?
