How confident are you on a leak free install of the CP and IC? Your boost control looks a little strange; it takes a while to reach target, then you start to overboost, it pulls WGDC and you drop below again, which repeats. It might have even happened one more time if you went to 6k+ rpm. Also, your STFT are very negative. I dont think ive ever seen 20% fuel getting pulled like that before. To me those things suggest a leak after the MAF, hard to be certain though since you are actually able to reach boost target eventually. |

Anyone got thoughts on the two random knocks? Wondering if its just noise since one is low RPM and the 2nd is mid shift. Really cant believe how crappy the timing looks. Been trying to chalk it up to crap CT gas, but i get the same behavior with the 91 tune.
https://www.bootmod3.net/log?id=5e89...0b436a66a1a264 Running 93 octane with boostane. Sport+, Paddles., Stg2 and XHP Stg3. One step plugs at .024 (replaced them and coils with eldors about 200 miles ago) Second pull, same spot, no knock https://www.bootmod3.net/log?id=5e89...90c608068500f6

https://f30.bimmerpost.com/forums/sh...als+for+charge https://f30.bimmerpost.com/forums/sh...oost+leak+test There needs to be some resistance when you install the CP onto the IC. If it just "falls" on and you can rattle/wiggle it back and forth easily even once it is all the way on and clipped, its probably not going to be air tight. |

adding boostane hasn't helped as much as it did last season, so i'm guessing the gas quality is really bad right now and rising IAT is exposing it. |

E85 has roughly 30% less energy density than gasoline. You cant just add a bunch of E85 (without switching to an ethanol tune) because your fueling will be off. Yes, the DME will try to compensate with fuel trims, but you really dont want to do that beyond a few gallons of E85 to a full (remaming) tank of pump gas. Bottom line you should do the test using 100 octane. If long term you want to start mixing E85 into pump gas to achieve higher octane, that is a separate conversation. |

Just stick with your dinan software and reinstall original catalytic converter. If you want more exhaust note, you can install aftermarket exhaust or do resonator or muffler delete for cheap.

7.1 has been out a while. Most are satisfied with 7.1. I never read of idling issues. Just don't delete your 6.4 tune if you want to revert

Been busy and haven't been able to share this yet (or even go on the forums) but man 7.1 feels refined almost stock. definitely feels better at lower rpm.
Anyone care to chime in? 2nd gear pull 2500-7k https://www.bootmod3.net/log?id=5eb8...0b430ed5ce443f
