Motorism Posted January 21 Report Share Posted January 21 V42 Normal test.llgxV42 absurd test.llgxHello, I've fully mapped my Mini R53 using traditional knock detection (ignition only). Everything works well and ignition trims are coherent when knock level is above knock threshold. Then wanted to try Normalised knock and I'm facing a weird issue : when knock level is above knock threshold, knock ingition trims are moving but instead of seeing 1.0 deg/knock event of igntion retard as calibrated, I see only 0.1 knock I-trim. I thought I had some gain to adjust but I found nothing. Then I tried to make an "absurd" test by setting the knock threshold very low compared to normalised level, and instead of seeing very high and sudden knock retard, I only see the knock trims slowly ramping up. To sum up : when I use Normalised knock, I see knock Ignition Trims being about 10 times less as they should be (0.1deg of retard instead of 1.0 deg of retard) Am I missing something here ? All the gains look well calibrated, I don't understand... PS : I see knock events counter incrementing as it should Quote Link to comment Share on other sites More sharing options...
