Stock si with knock on 2
I had my stock si tuned by a reputable company. The cal had -5 timing pulled from 2 and -2 from 3. I asked about this and was told the k20z3 tends to knock on those cyl so he pulls the timing from them. Does Hondata agree with this? I have set them back to 0 and have noticed a few knocks on 2 but only under part throtthle around 3k. By a few knock I mean 20 min of various driving and I get 3-5 knocks on 2 never at wot.

knock ?????
i datalogged for 5min and got more than 2 knockin cyl in 2 3 4 wtf ??? anyone else having the same prob
sounds like a bandaid tune. I heard a long time ago that cylinder 3 runs a little hot on the K20A2 motor and that adding 1 to 2% fuel helps keep it cooler.
I've notice my car will knock in Cylinder 2 only basically. out of like 10 long logs I've maybe seen 2 knock counts in cylinder 3.
I think there is some adjusting that needs done to the knock sensitivity and or knock tables if your A/F ratios are spot on and your not running any more timing than what is found in say the MAF tuned calibration.
