KNOCK

I tried to eliminate the knock in my engine but instead of going down the count went up.

2002 Civic SI EP3
K20A3 JRSC-R

Two datalogs in 3rd gear and the calibation are included. Could someone take a look and see where I messed up at, also do I have belt slippage and how do I Tell.

It is too lean between 1000 and 2000 rpm at medium to high load. Tables otherwise look good.

How do I make it a bit richer or add more fuel to the appropriate areas? What % do I add and where to help? thanks.

Actually, I think the low speed cam tables need adjustment too. What calibration did you use to start with? The low speed cam tables are not the same as the starting calibration we supply. I think the retarded cam might cause some of the knock.

On the low speed cam advance tables copy the whole of column 9 to columns 10-13 Datalog again and see what the AF and knock is.
