    Help with interpreting my MHD logs?

    What’s up everyone.

    was hoping someone could chime in and read some of my logs to tell me if something is wrong.

    car is a 2014 335i with VRSF intercooler, charge pipe, and cat less down pipe. Tuned on MHD stage 2+ 93 octane. I’m getting a lot of timing correction in pretty much all 6 cylinders. Some correction are more. Than -4 and I’ve seen all the way to -8 in some cylinders. Spark plugs and coil packs are pretty much brand new with less than 1000 miles on them. I usually use shell 93 but my last fill up was with another brands 93.

    Honestly car runs fine and pulls hard. I wouldn’t even think anything is wrong until I look at the logs and see the corrections.

    I didn't read the post fully before looking at the logs and first thing I saw was the timing correction.

    It doesn't log a Knock value, but I would assume it's knocking because its consistent across all 3 logs.

    Flash a lower octane map, like a 91 map and see if it still does it.

    With these DME's you may see knock every once in a while, but not consistently. It's doing it's job, but it shouldn't do it all the time.
