2020 M2 Comp DME unlock journey.
Wow what a pain in the butt getting these newer DME's to unlock/flash. Miss how easy it was to flash my 19 m2 comp, this 2020 is fighting me every step of the way. While we removed the dme which was fun, then had a local tuner unlock the DME now I'm up to the point of flashing but its requesting a force flash. Not finding much on the subject when searching and have a message into BM3 already, though was curious if this is the norm regarding "force flashing" when one has a DME unlocked? Assuming it will brick if there is an issue Anyone else know more on this or have done similar?

Update: BM3 has some great customer service. They walked me through it, flashed our 2020 M2 Comp with stage 1 93 file.

Thinking the same. Wondering if it can yield better 60-130's with different shifting rpm's, been leaving it in auto after shifting manual into 3rd. Would be tits if she can get in the 8's with a splash of E85 and some nicer weather.

Hell yeah!! I’m not too far behind you… trying to get this car sorted out. Purchased it used with 4k miles on it, already had a lot of warranty work done. Once I feel it’s “safe” to move on, I’ll do exactly as you’ve done here. Baseline, 93 tune, then I’ll try a couple gallons of E85… then onto a stage 2 E85 tune.
My wife’s X3MC was a beast on an E30 tune. So I know these lil cars respond well to better fuel for sure! Good luck, keep us posted. |

That's boring, I know. A good friend tunes a lot of BMWs, specially the S5x platform, and you can check his Instagram for 100-200 with stage 1 and 2 (with ethanol, too). Stock turbos go as low as sub6 100-200 (sub 6,5 60-130mph). Check it out at @prospoolfreaks |

This makes sense or at least it feels like it drags on waiting to shift in automatic mode up to 7300ish (not sure what it shifts at actually). Will attempt to manual shift lower in the RPM range. There has to be a thread on this subject.

Thank you sir! It's an 2019. Alpine White, loaded up... Pretty cool little car so far.
It's nice talking to like minded people on here, that's for sure. I came from the Porsche and Mclaren world, and there are some pretty cool guys on those forums as well, so it was nice to see some on here too. Congrats on your latest M2C as well. I look forward to seeing what you do with it moving forward. If you decide to do downpipes, are you thinking catted or catless versions? I'm leaning towards doing catted and HOPE I can still pass my emissions test each year... I don't want the hassle of doing a hat dance to get it to pass, I'm too old for that crap anymore! HaHa!! |

Was going to just flash stage 2 93 file on stock exhaust since others have done it prior but said the heck with it and ordered the CTS catted ones. On my last M2C I went with a resonated DP, then added the AA single mid pipe. Ended up removing the mid pipe since I didn't like the sounds and kept the resonated dp on. No difference in performance from what I remember. Hopefully the CTS dp's are pretty good.

Safest for the turbos is most liked cat-less or resonated Dp's but personally I dislike any added smells. Even though the secondary's do a good jot helping remove some of it. Aside from smell I dislike rasp hence high flow cats are going in lol.

Incidentally, I did speak to AA today, and they recommended a resonated mid-pipe as opposed to their none resonated version if I weren't doing catless dp's. So I'm on the fence on which direction to go currently. |

Having had the single pipe AA mid, i want to leave on the stock mids with a high flow dp for now. Only way i'm switching to AA mid's if they come out with a version that has larger resonators, the ones on that thing aren't do squat imho. |

Said the heck with it and flashed stage 2 93 file today as I await till the dp’s arrive. Wow bm3 must have revised their ots files, so much easier to drive in sports+ than I remember from my 2019 m2 comp. Stage 2 power just feels so right some say stage 1 but I say stage 2 hands down 💪🏼
