please look on knock level....
the value 1,99V it is real knock? or it should be only noises?

ignition is very conservative
setup :turbo k20

There is knock at 6300 rpm. Ignition might be low but it is a fair amount of boost (1.3 bar). What octane is the fuel? Reducing the water temp might help too, as will water injection.

thank you.

it normal street fuel, euro 98

it is really strong street honda, this log is from dyno, produced 540HP and 510Nm, and on street fuel boost 1.3bar...

I will try little retard ignition, now is constant 13 degree I will try 11degree.

last question, so 1.99V it is knock always? or it is hard to you, and you must see complete log, then you can say knock or not...

thank you

1.3bar boost in 98 octane is a lot (98 octane RON I assume).

The size of the spike in the knock level shows knock, not the voltage. If you graph the knock voltage then the knock is a sudden spike to around twice the average level.
