05 OZ turbo build
yeah it pulls pretty good up there. like i said im hitting peak hp at 6400 rpm so theres definitely pull! plus its nice to have all that room. odd thing is my low rpm high load knock im getting. around 3k it realls starts to knock then carries on throughout the entire pull but if i start higher up in the rpm i wont get any of the high rpm knock..
Your crazy 7k on top end i was nervous with 6400. English claimed it was false knock when tuning me and changed knock sensitive and a couple other things i believe. Car pulls awesome every time. Also on SD though.
haha ok ill try to get a vid. but the knock is around 130-140 load in 3rd gear and around 2750-3250 rpm and i can FEEL it so i know its not fake ill just lower the timing i guess but it doesnt seem that high at 5 or6* i think i hit max load at like 250-260
Adjust the knock tables in the problem area to clean up the noise.
The multiplier isn't super useful on the lower rpms because its used in junction with the rpm to create the noise height knock must exceed.
In other words as rpm raises the noise threshold for knock raises with it using the multiplier.
Since low rpm noise thresholds can be undesirably low you can set knock to be ignored up to a load point and rpm point which takes care of the low stuff. There should be a table of rpm points and load thresholds you can set to conquer persistent false knock via rpm by manually raising the bar.

I was talking with Aaron from ER when Ryan and I were down there and he was explaining the frequency difference between the 4G94 engine and the 4G63 engines for noise. My trip home I noticed I had not gotten a single knock flash so I was nervous he disabled my cel flash on knock. I pulled the rom and seen he turned all 3 multipliers up to 24. Timing is still the same. Was still nervous at first but everything is running great and very very seldom do I get a knock flash ever.
