Low rpm knock count

Post by Knox » Tue Sep 04, 2012 1:39 am

Hello,

I have some serious knock count but only around 1250rpm when rpm goes down. I know that this is not knock, just knock sersor hears some sound from the engine but i wonder why and how can i fix this ?

Here is my datalog, please check it spunkster for me.

Thanks.

I found the problem, problem is with the knock sensitivity tables. Now i use stock k20a-itr knock sensitivity tables and there is not knock. This calibration inside the ecu is loaded when i bought (i bought kpro used) the ecu, so may be old owner has camshafts and he modified the knock sensitivity tables. I'm running with stock itr cams so i use stock knock sensitivity tables and problem solved.
