amin vp Posted April 15, 2023 Report Share Posted April 15, 2023 Hello, I have an link xtrem on a BMW M50B29 turbo engine with 8.5 CR on which I added Bosch KS4 Knock sensor my problem is that even if I ride with a very low timing around 4 degree at 200kPa with pump gas I already detect knock . Do you really think my engine has knocks at such a low ignition timing? You will find attached some logs files . Waiting for your precious advice, thank you in advance Log 2023-04-12 5;18;04 pm.llg Log 2023-04-12 5;28;11 pm.llg Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 15, 2023 Report Share Posted April 15, 2023 I would say more likely the knock control system hasn't been set up or tuned correctly. The knock frequency you are using is pretty odd. Quote Link to comment Share on other sites More sharing options...
