Knock Sens. Cyl.1-2 more sens. than 3-4, reading knocks.

Post by Slinky » Wed Jun 06, 2018 3:14 am

G'Day Guys, struggling to find info as to why knock noise threshold for cylinder 1-2 is lower than Cyl 3-4.
Reading a great deal more knocks in cyl 1-2 than 3-4, wondering if it's just noise.

No knocks audible. Noticeable Ign retard.

2012 TSX M/T K24Z3

See attached cali and datalog.

Many thanks Gurus! <3

Have you tried reducing the timing to see if it has any effect?
