Knocks in CYL 3#
Posted: Tue Aug 13, 2019 7:50 pm
Hello, i have a civic SI 2011 with just K&N SRI.
In a 30 min datalog i had 77 knocks only in the cylinder 3 and always at the same RPM range. (2750-3000) and in part throttle. In full throttle the AFR is OK and no knocks. Im wondering if is real knocks that i need to reduce the timing in those RPM range or are false knocks because of the resonance at 3000 rpm with the intake. I can't upload the datalog because is too large. what do you think, real or false knocks?.
Thank you
