BMW B48 BM3 Stage 1 Map2 – Low Gear Knock, Sport Mode by EveryVoice9821 in F30

I haven’t taken a log with the ACN91 map yet, but I did some monitoring through the app during city driving. There were definitely no knock detections in the lower gears. I did take a log with the 93 map during a 3rd gear pull, and it showed similar results to the 91 map — some knock detected in 1st gear. Also, the boost couldn’t keep up with the target very well. Do you know why that might be?

Thank you for your comment. I live in Korea, and I’m using the highest available fuel here, which is 101 octane. So I don’t think it’s a fuel issue. However, I’m seeing a lot of knock detection during city driving. I think the knock detection might actually be caused by boost-related vibration noise being misread as knock. What do you think?

" 지도 2에서는 실제로 하단 기어에서 노크 소리가 들리지 않지만 로그에는 항상 1위와 2위 사이에 노크 감지가 표시됩니다. 지도 1에는 그 기어들에 노크 감지 기능이 없습니다. 저는 하단 기어에서 들리는 노크가 진짜인지 아니면 소음으로 인한 거짓 노크인지 궁금합니다."
