Chris R Posted January 23 Report Share Posted January 23 Hi, I'm struggling with setting up knock control on an the above. I read the below from an old forum post but it doesn't make sense to me. The version 5 may be wasted spark but it's sequential injection. It has a cam sensor and I'm pretty sure is capable of 720 sync. Why then can it seemingly not do individual cylinder knock control? On my logs the background noise on cyl 1&2 are identical as are cyl3&4 but I can't figure out why? While I can adjust gain settings for background noise from front of engine to closely match the rear two cyls up to 4500rpm, after that the traces diverge then re-converge toward the red line. No gain setting seem to see the two pairs of cylinders recording same background noise levels. I have confirmed with det cans it's not knocking. I'm more used to dealing with individual cylinder thresholds so you don't need to worry so much about individual cylinder gain. Quote Link to comment Share on other sites More sharing options...
