I've had my 2021 M2 Comp for a month, it came from the 1st owner with ASD disabled and a Dinan exhaust. My one disappointment with the car was how quiet it was. Mind you I am coming off a GT4 with a $6k titanium JCR exhaust, so it might be perspective. However I turned ASD on via expert mode on Bimmercode, just to see what it was like, expecting to hate it based on nearly universal online hatred for it, and I actually prefer it. It doesn't sound fakey to me and I don't hear a drone. For me it turns driving the car into a sports car experience, when before it felt like I was driving a sports car with a Camry Hybrid soundtrack dubbed over.

Is ASD different for the Comp models compared to earlier? I just wonder why everyone seems to hate it when I think it sounds better.

Glad you're not an ear surgeon

I never got around to turning it off in my M2 and it was fine.

Driving my M2C home I didn't get more than 10 miles out before it drove me crazy. Once at home I installed the harness to turn it off and haven't looked back.

I honestly forgot ASD was even a thing. Just gonna leave it.

Its so bassy and boomy, I hated it. I had it for a solid 9 months so I surely gave it a try but prefer without it.

I turned mine off about two weeks into my ownership.

I tried to like ASD and I think it adds a little excitement when getting on throttle but most of the time it sounds like a buzzy swarm of locusts to my ears. 36k miles and it's been off for the vast majority of that time. Also...I turned burbles off. Car sounds much better to me now.

I remember feeling a cognitive dissonance because I initially liked the sound on the throttle in sport/sport+ and found it very exciting but at the same time I felt it was so incredibly lame for it to be fake.

What ultimately got me to turn it off though was the drone on the highway. I'm surprised you don't hear it.

Then later I got the AA EL Midpipe and never looked back at potentially re-enabling ASD.

I've recently turned ASD off. I've got a 30 mile commute to work and the drone at highway speeds was draining to me 🙂

Different strokes for different folks. I couldn't wait to turn that fake racket off, disabling it the moment I got it home from the dealership. But hey, I'm a geezer at 64 - I got over loud cars a LONG time ago.

Shortly afterwards I turned it off in my buddy's 2015 M4. He'd been living with it for years. He couldn't believe what an improvement it was to kill it off. His main complaint was the same as many others - highway drone.

Maybe it’s because this is a weekend toy for me and not a daily driver. I do essentially zero freeway miles in it.

[///MPhatic]

As do I.

[Moflow]

I don't mind it if i'm not on the freeway. On the freeway i'm basically never in sport or sport+ so it's not a problem. I love how the car feels when i'm rev-matching my downshifts and ASD is probably part of it? A lot of it is the throttle response and how quick the car is to free-rev but sound is certainly also a factor.

[ASAP]

As a driver... I don't particularly mind it... when I coded it off, it felt like something was missing albeit I have the stock exhaust... so we'll see how it feels once an aftermarket exhaust is on.

As a passenger... it's straight up god awful... you don't see how bad it is until you are no longer the one feeling the feedback from the throttle... it sounds so fake.

[Kikuchiyo]

I once coded it off but after a while had it back on. I am driving a manual and couldn't select gears to the engine sound as it was so quiet without ASD.

I don't like or hate it soundwise but I see it useful functionally.

Hmm, this is a good point. Although, I'll never be a passenger in my M2, ever!

[BigKutta]

You are not alone. I dont mind the ASD either and I think if you are sitting in the M2 with windows up, the engine sound by itself is nothing to enjoy anyway, so if it helps thats a good thing. Someone told me that the best way to hear ASD is to be cruising at a steady speed in Efficient, and then hitting the Sport mode and the change in sound is the ASD. That sound is not bad to me honestly.
I usually have my windows down to enjoy the sound of this car and when switching to Sport mode, I hear the majority of the difference in sound change from the outside, so I'm not sure how intrusive ASD really is. It hasn't bothered me to code it out

I don't particularly care enough about this car to not be a passenger, but all that aside... try it and it will all make sense lol.

[brad65ford]

the s55 is a weird duck because of the twin turbo and the placement of the dp pipes where then connect. Yes I agree, ever the asd on so it bends in sound.

[pz619]

I also prefer it on. The S55 just is not a great sounding motor regardless of the exhaust setup in my opinion. At least the fake sounds overpower some of the real "not great" sounds.

[NWest]

I had it on for the first week of ownership before coding it out.

I do daily highway driving so ASD off was a must, it gave me a headache.

[chris719]

It's too bad this car has analog audio to the back. I have considered but probably will never get around to designing a DSP box in order to manually control ASD volume and tone from my phone. It can be done with the analog I/O but necessitates the latency of additional A/D and D/A conversions.
