skeruno Posted April 14, 2020 Report Share Posted April 14, 2020 Hi there, Maybe you have some insight in this. I see knock trim while the noise is not exceeding the threshold. In the attached example you see that cyl 5 does exceed the threshold but all cylinders show a trim. You guy's have some insight on this? An other question, while im at it: on a warm start(ECT:90C) the engine is running lean for a short period of time(2 mins) which is normal. Is there any way to compensate for this? Thanks a lot!

remski2 Posted April 14, 2020 Report Share Posted April 14, 2020 Look at your: Advance delay Advance rate in the Knock Setup section. Quote Link to comment Share on other sites More sharing options...
Vaughan Posted April 14, 2020 Report Share Posted April 14, 2020 If that's a PCLink log then it is possible that knock occured on all cylinders but the log wasn't fast enough to capture it. Have a look at the post start enrichment settings if the engine is lean for a time after startup. Quote Link to comment Share on other sites More sharing options...
Ducie54 Posted April 14, 2020 Report Share Posted April 14, 2020 Knock threshold would have occurred in a earlier part of the run. It then is applied to that cell each time after unless reset. All in the help file. remski2 1 Quote Link to comment Share on other sites More sharing options...
Rob W Posted April 16, 2020 Report Share Posted April 16, 2020 Do ECU logging for the same selected parameters at 100hZ and you might see it will pick up the knock event. Had the same issue. Quote Link to comment Share on other sites More sharing options...
