I'd like to hear from folks who LIKE the sound of Active Sound in their car and installed the bimmertech amp. I'm hoping it isn't unreasonably loud. There is a cable available to disable the sound but I really love it. It makes the car feel faster and is just fun. In fact, I would find it entertaining to code the m6 sound in my f31 grocery getter

Is it going to be annoying once I receive and install my amp?
Is there any way to attenuate that engine noise signal?

Thanks for your support

With Bimmertech amp, you will have to code off the active sound. It's extremely loud and drones as well. I would not install the amp unless you know how to code the AS off immediately after installation, since the AS is unbearable with the amp.

You can play around with the DSP tuning to make ASD reasonable. The default BimmerTech tune makes ASD unbearably loud. I'm using a slightly modified version of "Marshalltj _Aug 3 _Revised_TUNE_BSW_LHD" and I feel the ASD is only slightly louder than the base HiFi amp and still very reasonable. (I modified it so the center channel is only getting input from the front channels and I turned down the level slightly)

If you have the time, try all the different settings people posted and tweak your favorite one as needed.

ASD audio level isn't controlled by the head unit's volume control. So a quick way to tell if the ASD is going to be too loud is if you have to turn down the volume for your music compared to the original HiFi amp.

Agree with ecompk, you can tune the amp by pushing down the gain of channels in order to make ASD less loud. I am doing the same. Indeed I have tuned my amp in the way the ASD is little bit quieter than factory hifi amp.

Another point to note is the EQ. You really need to play around the EQ (best using a mic to fine tune the EQ using the ATF software) to fit your cabin acoustic environment. By doing so I get a very impressive music quality (even with stock speakers) and a very balanced ASD sound.

thank god I don't have ASD (they didn't have $hit in 2012!)

So my active sound is gone when I plug in the bimmerTech. I don't have access to a Windows laptop to check the tune yet. Any thoughts on why?

[ecompk]

Maybe they forgot to load the BimmerTech tune when they shipped you your unit. I vaguely remember the default tune being very quiet.

I think there's a way to load the tune with a micro SD card if you don't have a Windows laptop. I think I read that some where, but I haven't tried it myself.

You might also want to play with the balance and fader in the head unit to make sure each individual speaker is playing audio. I got a bad cable where a few of the pins came loose so I would randomly loose audio from a corner of my car.

Reviving this ancient thread but I figured it's better than starting a new one on the same topic.

I am in the same minority as the OP who happens to feel that the ASD is working pretty well and adds a positive experience

At the same time, the Hifi audio system is really lacking. I recently bought this car (2016 F31) and it was really apparent that it's not on par with even the Mazda I was driving before.

So my question is regarding the tuning of the BimmerTech amp to keep ASD but make it fit the overall volume of the system.

I am more of a plug and play kind of person, and have not modded the car in any way. I am fully comfortable dropping in a plug n play BimmerTech amp replacement but might not be able to do the tuning needed. Does anybody have tuning files they could share that allow ASD to stay enabled? I am picking up a BimmerTech PP82DSP amp.

Thanks!

There's a separate thread full of PP82/86DSP presets, grab some from there and test them until you find one that you like:

Thanks, looks like several people have created tunes to work with ASD! Will ask in that thread.
