BMW must be constantly upgrading Launch Control and AWD
https://www.caranddriver.com/reviews...y-the-numbers/
That is getting wicked fast for basically a M5C. Has to be a better LC and AWD TC system. |

its a year newer? there has to be things that have changed, even if its just software. for the LCI, add some hardware from the M8C into the mix and hopefully the M5 times come down even more

Not sure why but M8 feels slightly faster to me! Non comp both, I think better traction, despite M8 having horrid Pirellis and M5 wearing M4S

faster solenoids, better handling of higher torque, etc. im sure the software being tweaked helps too, but software wont be able to totally fix a hardware deficiency |

The 2018-2019 M5 would shift out of 1st gear early if it couldn't get traction? (not sure if that is the exact reason) It would cause a dip in boost though and you would enter second down on power
Ever since my last update at the dealer my car ('19 comp) no longer short shifts in 1st when launching and my 1/4 mile times are very consistent. It will immediately shift out of second into 3rd if you are spinning too much now though. So it does seem like they are updating things from time to time The 2020+ m5 and m8 have a slightly different transmission which never seemed to have the above issue Evolve also has a TCU tune that seems to fix this issue if you already tuned |

So tcu tune would give similar results on 2019s? Evolve and few other vendors have similar offerings for $500.

I'm sure there are some folks around here that actually have it though and the owner posts here so you might be able to ask him |

We get the new M8 transmission software, according to my BMW tech (which I think is prob one of the best out there. Trusted 100%)

As for downpipes, I don’t want to do full downpipes either, because of the fuel smell. I was thinking about doing only primary (upper downpipes) and not secondaries which would allow for a stage 2 ECU tune. Do you recommend it? |

I don't understand BMW, which boast itself to have connected cars.
It would be easy, to update TCU ... Tesla way . During the first 3 years of a vehicle, this update service should be included. All they do with their connected drive is collect a ton of data without our knowledge. Where does all this data go? What data does it collect? Who have access to this data? Is it written in our contracts they collects this data? Do they have the right to do so ... About TCU software of the 2020, it should be at least an option to"upgrade" the version of the older version, since it's just a software... BTW, it's very easy right now for them to track flash, piggyback, your position, your speed without opening the hood of your car ... https://www.altoros.com/blog/bmw-del...g-ibm-bluemix/
