First time reviewing BM3 logs - pointers needed
Hi there,
After some technical issues which needed sorting out, I managed to get out and log some time with my car running Stage 2, 93 Octane. I see that there is some knocking detected, which is obviously cause for concern, but does not seem to be at full throttle or under load. Not sure how to interpret this. Is someone more knowledgeable able to take a look and see how these logs look? Is the timing okay? It seems to be to my beginners eyes, but there is a lot of data here!! Many thanks! https://www.bootmod3.net/log?id=5ec0...729b721306b894 |

This log is unreadable to me. There is too much noise. aka useless data that is getting in the way of diagnosing issues.
What you need to do is put car in DSC Off mode, start the log, then apply full throttle at ~2500rpm in 4th gear, continue logging until redline. Choose one gear and do not shift gears during the log. |

This log isn't showing any useful data. It looks like you just cruised down the streets in some stop and go?
You need to go from 2500RPM from 3rd gear all the way to redline and ideally into 4th gear and up to redline again. Use Sport+ at a minimum or DSC completely off. |

I also suggest OP fix whatever is showing his gears incorrectly. 0 gear, 0.16 gear, and 1.45 gear do not exist. No idea why it's showing like that in the logs. |

For me yes I start my log before I do the pull and end it shortly after to keep things minimal. It's not necessary to do though. I just see no indication of you doing a pull in the log you posted. |

The current version of BM3 has an autolog feature to start the log at a set pedal input level (set it to 75% or something high) and an auto cutoff for a specified number of seconds after liftoff
