The ASD masks the actual engine sound, so you can't be aware of what sound is being emitted externally from the car pretty much at any speed. You must roll the windows down to hear the the exhaust, but at lower engine speeds for example, the speakers will even cover that up.

Lmao, I thank you for backing up my point.

A couple of annoying things if you're wanting to hear the actual engine/exhaust from inside:
1) No natural engine sound available to your ears, unless you roll down the windows and rev it. In other words you are prevented from being aware of what the engine/exhaust sounds like.
2) The ASD does not correctly measure engine load to replicate the sound and volume appropriately - it gives bad feedback. That 75-80mph example is one example.

So it's like while driving you're in one reality with the real engine/exhaust (people outside of the car can hear this). But inside your car, constantly fighting to replace that reality, is an imposing, artificial, unfaithful video-game sound effect generator. .

Then before I decided to order the Technic ASD harness, I removed the 122 fuse for one full day. All the fake engine noise is gone. It is really unbelievable how the real engine sound is totally weak sounding. I think ASD even alters with inside-the-car exhaust note, the sound that I thought was from the exhaust coming from the rear of the car, that sound became like 40% quieter. In Sport and Sport+, the boom boom is just gone. I was not dispointed but very very surprised.

That day I wonder if I could live with this M2 without the boomy fake engine noise, and have a slightly better car audio. The answer is a big NO, even though it is fake, it adds a better sports car sensation while driving. I really need the fake engine noise to enjoy this car, even it adds some tiny hiss to the audio, so what. To my ears, the fake noise is real enough to make the car sounds powerful.

Sure many of you will disagree with me, that is your choice. The point I am trying to make is that the trend on this forum points everyone towards removing the ASD, at first I even thought of the ASD as the enemy to the audio system. But in reality ASD is not as bad as what people think. What is the point of driving a great 370hp car with little engine sound or a crappy engine sound? Why not just forget that there is even ASD, and just drive the M2 with great sounding engine? Compare it with aftermarket exhaust or even the great-sounding original M2 exhaust, they are also a sound alteration from the engine, just in an analog/mechanical way. Why not think the ASD hold similar concept, but just in a computerized way?

There are several youtube videos comparing ASD and ASD-disabled sound, they do not show how much the engine sound is really muted. They do not do the judgement. You just have to try it for your self, remove the fuse #122 and hear it, it will amaze you!!

Agreed. I did the ASD delete, and also felt that it was too quiet. For me, the sound just adds to the character of my car. When I did PCD, the best thing I loved about the 1200+ return trip was the glorious sound it made. I still love it, even more with the 200 cell cat. I bought the car for the driving experience. Not too concerned about the sound system.

I'm Ok with the ASD ...wouldn't part with it unless I upgraded my exhaust.

2017 or 2016 makes a huge difference.

Not sure which MY it is for my M2, because it is made for Asian market. I tried to check but the 10th VIN code is "0" (zero) on my car, normally for US market it should be G or H.

But the production date is 07 May 2016, at a plant in Germany.

Whatever Model Year it is, the audio coming out of the HK speakers is just terrible.

May production is a MY2016, and yes ASD with 2016 is lousy.

Sprung for a iOS based coding app (BimmerCode ($30)) and while I was getting rid of the legal disclaimer iDrive screen and turning off the headlight washers, tried coding out ASD to observe the difference on a US spec 2017.

Wasn't dissatisfied with ASD per se, but, in a highway/cruise control situation, hard to imagine MORE steady state noise being desirable. And with this app, easily reversible, so why not give it a go?

First quick test drive impressions:

- Definitely noticeable difference in all modes, but really interested in an getting out for an interstate cruise to see if it's noteworthy
- I now can hear the workings of the turbo if I listen for it with the sound stereo system "off". With ASD on, I'd never before noticed it.

Will leave it for a few days, and form some further conclusions, but as easy as this is to turn on and off, could easily see me turning it off for long highway trips at least.

Are there coding apps like this for Android?

But ASD does not accurately measure load under all conditions so will give misleading feedback. For example it comes on disproportionately loud in response to only minor throttle application. This is not reflecting actual engine and exhaust response. So why is that a good thing?

Even with the windows up and interior sound deadening materials, the ASD masks what you would otherwise be able to hear of the engine and exhaust. Your brain naturally recalibrates listening sensitivity to its immediate environment, adjusting to the loudest sound source (speakers). So your hearing is being hijacked - entirely by artificial means.

ASD is supposed to provide some "expected" in-cabin engine sound. And yes it produces a plausible enough sounding drone noise for most people, but it's not reproducing the engine sound of the car you are actually driving. As sophisticated as ASD is, it's still a stop gap engineering effort. And the problem of a faithful engine sound reproduction remains.

Carly is $51.40 incl vat/shipping for adapter, plus $58.99 for their Android app.
Total $110.39! Cheaper to buy a used iphone and use Bimmercode.

$30 bucks for the iOS app. Total price, a little under $50, if you include the V-Gate Icar2 OBD interface hardware I ordered from Ried's Amazon link (at the top of this thread) for around $18.

I don't know about Androids

I was about to correct my statement, but you already did. Unlocking coding is $40 in Canada, plus $30 for adapter shipped.

Thanks, so $48 for hardware and app and $25-30 for a used iphone 4s w/ 9.3. Still cheaper than Android and you get a phone.

Cheaper than a one time coding fee and you get to do it yourself anytime you want.

That's entirely my point (this is part the reason I bypassed it) and judging by the responses to this thread is exactly what the people want. That theatre is what make them feel they're in a sports car.

Who said it was? Look at how many people post on here about 'what exhaust....' They are not interested in actual performance only the appearance of performance. They'd rather spend thousands of dollars/euro/sterling on parts that make noise and deliver zero gains than spend hundreds on actually being quicker....

Yup. The #becauseracecar crowd is all about image.
