    Default Knock Retard Worries

    Have been doing a few datalogs, looking like my KR values are too high at 4.9. I believe the attached is a 4th gear run.

    I have done many WOT logs and this is the only one with KR showing. Can anyone tell me if this is actual knock? How can I diagnose/ avoid it? I have some denso itv22s coming.

    99% of my logs are fine and dont show any KR at WOT.

    I had it on the dyno a little bit back and the guy said he heard audible knock on the second dyno run (5th gear at 3500 rpm or so) so didn't go any further with that run.

    I am running cobb stage 1 95 tune, but using 98 petrol. Before the dyno I was running the 98 tune, but changed it to 95 tune after the dyno
