M340i owners with jb4
Feel free to chime in, I took the jb4 off my 2017 340 and added it onto my m340 so far it feels a bit faster but the transmission shifting delay on wot is worse then on the f30.

Most likely because it's not optimized for the 2020 M340. I keep saying this, while it's fine to transfer the JB it's not optimized for it. That's literally why there will be a new one. I'm holding out still.

BMS will probably release a new firmware optimized for this car. It will be the same Jb4 just a different software
