2021 sdrive40i 0-60 (stock and jb4)
I'm not really a 0-60 guy, but was certainly curious to know what kinda 0-60 this little motor (in a big car) can do. Fuel is 93 octane mixed to e33ish with e85. Running jb4 with EWG connections installed.
Runs done within 5-10 minutes of each other. Car is a bit too slow do 60-130 runs, so not gonna bother there. However, it's definitely quicker and faster with jb4, as we'd all assume. This is without doing any setting changes to jb4 after installing EWG connectors, as I just sent my logs to Terry to evaluate. map 0 (stock) - 5.85, using LC map 4 (20psi) - 4.67, using LC map 4 (20psi) - 4.69, using LC map 4 (20psi) - 4.36, brake boosting Last edited by FloridaM5; 11-02-2020 at 08:12 AM.. |

Holy crap Man, that is over a full second improvement 0-60, WOW! This has to be a very noticeable increase in power.
Have you done a 0-60 without the EWG connections? Thanks for sharing your results. |

I'll be installing the Jb4 on my '21 M50i soon and am wondering about those EWG connections. Burger suggests not connecting them to start with, not sure why. Hoping to see the kind of gains you have realized, a second plus 0-60 is huge.

Little cooler weather...finally. And this was brake boosting...no launch control. This b58 is such a stout motor, for the little guy that it is.

I'd have to agree. Pretty cool. I tried one more time this AM via brake boosting. Built too much boost, spun tires in a meaty sorta way. So far, brake boosting is def quicker with this setup, for a good launch. Will have to figure out how much boost to build, or do some boost by gear work with the JB4 to see if another 10th or two could be achieved.

Launch control on this car is just not very aggressive. Playing with brake boosting this morning quickly showed me brake boosting will be the winner here. |

5.8s 0-60 is very slow for this car stock. Whats going on with that? These things have been documented well below 5.3, even car and driver has the 2021 mild hybrid X6 40i at 4.7 and 2020 X5 40i at 5.0

The weird part is, BMW rates the 2021 X6 at 5.3s and they at notorious for underrating 0-60 times, they usually don't overrate...like ever. Perhaps the .43% incline affected it? |
