Hi, I’m running Boodmod3 stage 2 ACN on my 2019 440i with a CTS High flow Downpipe, remus axle back exhaust, and resonator delete. I’m fueling at the Socal Arco 91 pump.

I took 3 logs (in sport rather than sport+) and in total I am seeing 3 knocks detected, some timing issues from cylinders 5 and 6, and some major HPFP crashes.

Would this mean I need better fuel? If I’m too inconvenienced by fueling anywhere other than at the local pump, do I request a custom tune? Go stage 1 ACN? Back to stock? Newbie with logs here and trying to do what’s best for my baby.

Those HPFP crashes are bad. I had far worse timing correction like -7 on some cylinders before a revision of my tune(-7 is pretty bad, and I asked my tuner to dumb down the tune by a lot). Your HPFP may be toast and needs to be replaced.

What do the logs look like on a different map?
