The ONLY thing I need to confirm right now is if there was some kind of delay/lag introduced on throttle input. I'm not saying it just to say it - I'm sensitive to throttle response and stock the B58/M340i response is phenomenal. The first thing I noticed after driving off with the JB+ is, at least in lower RPMs, throttle response seemed to be scaled back every so slightly. If I was to take a wild stab at it - the ECU is expecting certain results, and as the JB+ is rewriting boost, etc. under acceleration it is recalculating it to match targets or adjust for what it believes it should be getting. It's not inherently a problem - at all. I drove a couple more days on it - and it's fine. But, I'll remove it again to check myself on it. Car still drives smooth, not jerky transmission changes, etc. So far, so good. |

My comments on this subject are for entertainment and my own curiosity.
I do not work in the automotive industry so I must rely on the experts who do to fill in some of the gaps for me. I was at a DEFCON, when things used to be normal, where OTA, specifically the BMW OTA exploit CVE-2018-9322, was referenced. It is clear that an update does not need to be downloaded or approved for install by the user. That is clear as the above stated exploit was patched OTA by BMW. Isn't it possible that BMW could OTA determine if a DME was unlocked and if so, lock it remotely? There are a ton of attack surfaces that connected vehicles have (GSM, HTTP, NGTP etc). If you learned what type of encryption the OTAs used (asymmetric I assume) wouldn't it be possible to spoof an update with the parameters chosen by the user? I am sorry if this has been asked before. |

Download BM3 on your iPhone or laptop. Run a pre-scan via OBDP and send this to protuningfreaks (the owners of BM3) They'll read the scan from the ECU and tell you what the status is. Takes 5mins, costs nowt and the service from them is 1st class. |

Nightmare getting it unlocked where I am. Every tuner doesn't know or doesn't want to bother. |

So if a 2020 has been locked by BMW it can be unlocked? As opposed to the 2021's which at this point can't be unlocked? Just trying to understand this.

Yes that's correct. I believe the newer DME has some physical changes too if I understood Alex at mission tuning correctly.
