2020 M340iX Dynapack AWD Dyno Numbers
Hey guys! Just did a baseline dyno on our 2020 M340iX. Figure you guys would be interested seeing this. Car is completely stock. It's an early delivery and the first one that Irvine BMW got (thanks Yi Wen!). We dynoed at Road Race Engineering on their Dynapack AWD dyno (thanks Mike & Robert!). Ambient temperature was 85F in the dyno room. Regular 91 octane pump gas.
For reference, we put the M340i dyno graph up against an E90 M3 that Edmunds had brought to dyno at Road Race Engineering. |

Feels about right, seems it's more or less equal to my previous f30 with a tune

FYI, OP did say it is an early model. BMW did forget to limit the hp on their early M340i. I saw another post saying early M340 has close to 400 whp! Which match this dunk number. But BMW already knew about it, later model are all reduced power. Bummer

I've yet to see an ounce of proof on this.

We did get a letter from BMW some time ago informing us of a recall that needed to be performed. Luckily for us, the car was down for development work so we didn't take it in. I did read on another thread about the reflash. Looks like we're not taking it in lol.

"the issue relates to improper welding, therefore, the rear center headrest may fold in the event of a rear impact crash."

Good info. Thanks! That seems a pretty important recall to do.
The letter does not state what the recall was for so it's just speculation on our part. Will talk to the Irvine BMW guys and see. Quote:

You think Mission Performance fabricated the numbers? |

Wow hadn't heard about this.
I did notice that my car seemed slower than when it was new. I brought it back to have smart shield applied, and had an issue with the sunroof not closing. I wonder if they flashed it then? |

If BMW wants to release a car with "only" 382 hp, fine. But it's a bad move to send out early versions of that car with 430+ hp and then detune after a customer bought it based on the higher output. |
