hi, yes I know that knock count is not important in this platform but here is the situation; when I leave the throttle pedal while accelerating or cruising and and TPS becomes zero, there is a knock count on always cylinder four. As you can see in the datalog all the knock counts are when I leave the throttle and maf voltage decreased to 1.31-1.35v. Sometimes it just doesn't happen and sometimes I get 10 to 30 knock counts mostly on cylinder four. I scaled the maf just a little like -%5 at those voltages but it happens at stock maf values,too maybe not that much.
Do you have any idea why it happens or should I just ignore it?
