This is the best mod I did , car looks aggressive with bigger exhaust tips. I also think the stock exhaust sounds insane in sports plus mode

Just the other day, I was driving home from a park after doing some sprints with my friend. I was super tired, so I set the car into efficient/comfort and just cruised in peace with little to no effort while rowing through the gears (my legs were killing me, as I could barely move them). Big kudos to auto rev-match too. I love this car for what it is. Great to be able to choose your poison on any given day. |

Fellow M2C enthusiasts
Some great post of late!!! Thanks to all for sharing your journeys, including insights that only Poochie can provide . . . this forum is an incredible resource. Been hitting it hard at work, so time has been limited toward forum contributions . . . but I do keep up with the forum posts between patients and surgeries. Walking out of hospital yesterday and I could not help but notice that I got the beast's suspension height perfectly dialed-in with the MP Coilovers . . . snapped a quick pic. If only I could capture the glorious MPE acoustics. ///AVM |

Noticed something weird , cruising on 3rd gear around 40-45 mph and step on it there is a turbo lag and it takes some time for the car to pick up speed , anyone notice that?

You answered your own question brother. If you are in 3rd gear and going 40-45 mph, then you are lugging the shit out of your car. . . or, if you like, turbo lag galore. You need to wring your beast out a bit. ///AVM |

Really if I am driving in 3rd gear at 40-45 I am lugging the car ? I guess it's normal gearing at this speed , infact sometimes I am in 4th gear at this speed when I am coasting at that speed since you drive a DCT can you check which gear the car is in when you are in D mode ?

You are only lugging the car if you are in 3rd or 4th gear cruising at 40-50 THEN apply aggressive throttle . . . under which circumstance you describe experiencing 'turbo lag.' If I am in just cruising at 40-50 mph (Efficient and DCT Automatic modes), I will be in D7 and about 2K RPM. If I am just cruising at 40-50 mph (Sport and DCT Automatic modes), I will be in D5 and between 2-3K RPM. If I am just cruising at 40-50 mph (Sport Plus and DCT Automatic modes), I will be in D4/5 and about 3K RPM. How do I know? I just went out and tried all of these modes. As expected, applying aggressive throttle in any of the above scenarios is associated with some lugging and turbo lag. . . albeit a little less as you move from Efficient to Sport Plus modes. This pertains to why I almost never use anything other than manual mode . . . the MT fanboy in me will not give up control of shift points. I believe you own a MT, so I see no reason for you to ever be in 3rd or 4th gears and going 40-50 mph . . . unless you are just 'Sunday cruising' around town. Under such circumstance, I cannot imagine the need to apply aggressive throttle. If you do find such need and do not want the lug/lag, then downshift to 2nd gear before aggressive throttle application. ///AVM EDIT: Not to convolute things, but this topic pertains to just one reason why the Porsche PDK is so damn good. If you are ‘cruising’ in PDK automatic and Efficient modes at say 40-50 mph - as with BMW DCT - you will be in 6th or 7th gears. To avoid lugging/turbo lag you have two options. (1) give a quick pump release of the throttle and the transmission will switch to the lowest gear possible, then you can apply aggressive throttle with no engine lug and minimal turbo lag. In essence, this maneuver equates to manually downshifting to get RPMs up before applying aggressive throttle. (2) apply WOT. PDK will similarly shift to the lowest gear possible followed by max throttle and, again, be associated with no engine lug and minimal turbo lag. Both (1) and (2) above can occur very quickly BUT not INSTANTLY. In other words, there is a bit of a delay, but the delay is no longer than the time it takes to manually downshift. These maneuvers prevent lugging and minimize turbo lag . . . just as occurs with downshifting in MT or DCT manual mode. Last edited by ///AVM; 10-25-2020 at 06:08 AM.. |

Anyone else notice how twitchy this car is at high speeds? - Say you're doing 90+ mph, and want to change lanes fast or take a curve at those or similar speeds, the car feels a little "nervous" or unsettled.
It's a little tricky to point it with precision. I'm not sure if it's because it lacks aero (like the CS has) or if that's the nature of a short wheelbase. It doesn't feel "wrong", per se, but somewhat awkward. Could this be the result of all those things, in addition to sport or sport plus steering modes? I truly believe nothing is wrong with my car. Maybe that's just a characteristic I have to get used to? - I wanna say that my e46 M3 felt more stable or predictable at those speeds. Or maybe it's all in my head. I don't know. |

In terms of street cars, other than overall shape of the car, aero is pretty consistent across modern like for like cars. There are so many factors that can affect stability, such as wind direction and any cambers on the road. I wouldn't say the M2C lacks any "aero" that would result in depreciated stability. Other than the wheelbase metric I mentioned earlier 😉

Wont argue with anything stated, and the short wheel base is a very reasonable explanation. That said, I honestly have not appreciated the M2C to be (overly) 'sensitive' when it comes to handling at high speeds. By 'sensitive' I assume j23 means (overly) responsive to steering inputs?? Perhaps all relative to where you are coming from? ///AVM |

I suck at describing these things.
Car feels a little floaty during high speeds. Could be the wheelbase. Or perhaps the electric steering that I'm not fully used to yet. When I would point the e46 M3, it would go there. It's almost like the steering on the M2C is trying to catch up with my inputs. Again, maybe I'm just not fully used to how this car drives. It's nothing like the e46 M3 - that's for sure. Feels twice as fast too. But what do I know. This car is spectacular nonetheless. |

I can't say I've driven the M2C at excessive highway speeds but I have seen triple digits on track several times and places. I've not noticed any unstable feeling. The combination of short wheelbase, and low profile tires does make it hyper sensitive to road conditions, more so than older BMWs, in particular 5 series that I've had. I've also heard the EPS may react oddly to quick inputs and does feel different than hydraulic power steering.
