BM3 datalog cyl 6 ignition timing = 0 + knock detected = 72
Hello all
2016 340i xdrive, stage 2.0 93+ OTS map. VRSF catless dp, cts intake, snow methanol injection. 94 octane fuel from Petro Canada. Logging last night produced some scary results. Power was there, 2 runs were done both with and without methanol. Without meth produced 480whp on virtual dyno, and with meth made 516whp. The logs are scary, it's showing a constant knock of 72 on all logs and cyl 6 timing is showing steady 0. Is this an error in logging or is something foul at play? Any insight appreciated, sorry if I left anything out. Logfile: https://www.bootmod3.net/log?id=60af...90c62c69a3f414 |

Oddly enough, yes the car seems to be driving perfectly fine. No shaking or any sounds that I could identify. The virtual dyno numbers were almost identical from before it was happening. I was suspecting injector or plug as well, this seems to be the easiest place to start.

Update: It seems there was an error with the logging, the values shown belong to the category below it.
I did another run today, I still see 2 knock events in the low range. https://www.bootmod3.net/log?id=60af...90c62c69a3f634 Is this ok? |

mmm, with the methanol your timing should be better... i,m not very familiar with WMI and settings and if you can adjust, but i think WMI should improve timing

I switched back to a less demanding Stage 2 tune and it seems to have done the trick, this log has much better timing - https://www.bootmod3.net/log?id=60b0...0b4342ae6f9482
