Hi guys

Here are some videos of my retrofitted ASD in action.

First half of first video, comfort mode, barely noticeable (the way I want it). 2nd half of first video, sport mode, more noticeable.

Second video I messed around with F80 M4 settings. Way too aggressive and noticeable, especially on my aftermarket amp & speakers. What also sucks about the M4 setting is that the volume is constant on Eco-Pro,Comfort and Sport. Probably because M4 has different way of adjusting driving modes.

Hi guys

I thought I'd post of this thread to share my progress on retrofitting Active Sound Design to my 2013 328i MSport.

To start off with I ordered the module. It has various part numbers, but apparently they are all the same: 65129352264*; 65129326555; 65129343317; 65129353021; 65129362445; 65129362445; 65 12 9 322 712 (03/12 -> ); 65 12 9 302 536 (03/12 -> 07/13).*

I could not get a part number for the connector so I will be making up my own.

Next up I got the pin assignments from ISTA Rheingold:




Here is the inside of the connector:




I then transposed all the pin assignments onto an image to make my life easier:




I then continued to only connect power and the CAN signal.




ISTA detects the new module
ISTA before:




ISTA after:




E-SYS detects the new module:




After this I flashed the ASD module. I used a modified FA where I changed the production code typekey to 3C17 to ensure it is a production code that included ASD.


Here is the FDL edit view afterward:




Next thing I must connect the feed from NBT head unit and output to the AMP. I first need to spend some time to make proper connectors so will update all you guys once I progress further.

Very excited to see this retrofit work!

Great work!

I have ASD and coded it off. However after a few months I found the silence deafening so to speak and coded it back on.

Great thread. I love reading about DIYs like this. Looking forward to your progress.

Very interesting!

[fraidoon]

I am a bit confused. What does this exactly do? Is it like noise canceling feature?

Not really. It is about the car making the 'right' kind of noise. Back in the day they would work intake/exhaust, now they just play recorded sound through the car speakers. This is becoming commonplace even in 'high end' vehicles such as the M cars.

Would the output be any different from a NBT vs CIC? Am very interested in doing this but not sure if I could build the wiring harness.

Curious whats your running total for cost?

[BmwFlooner]

This may be a dumb question, but why isn't the approach to try and pipe in the actual engine/exhaust sounds into the cabin by bypassing the sound-deadening material?

Probably because the actual sound sucks!

[BmwFlooner]

If the actual sound sucks, but the ASD component is faithfully recreating the actual engine sound based on engine parameters...I don't follow you....

That's a big assumption that the ASD is faithfully reproducing the engine/ exhaust sound.

I'm sure this will kill a person lol. Exhaust fumes in the cabin.

I paid R3000 (Around $290) for the part, new from dealership. Then paid R100 ($10) from a scapyard for the connector. It's nearly impossible to get a ASD connector. In the end I got a HiFi amp connector (From E92, even amp connector from E46 will work). You just have to trim off some of the guides on the outside of the connector.

Just a quick update. The module is connected and it is working. I must say it is quite a bit lounder than I expected. Might be because I am running aftermarket amp & speakers. Will first try and change selected engine and turning amp gain down a bit to balance it out.

All in all, this mod was a lot easier than I anticipated.

Any chance you'll have a detailed step-by-step guide for those of us who are less DIY inclined?

i can confirm it IS louder with an aftermarket amp installed (but not all amps - with my ms-8 there was no difference, with xd800.. night and day). It went from not/barely noticeable (pre amp install) to WHOA (after amp install). I also found the diesel is waaaayy louder than f82

I'm just going by what BMW claims. So maybe you're right.

I had been reading about how other car makers like Ford (with the Mustang) solved this problem, and while I didn't get into the specifics, they basically funnel noise into the car past the sound barriers vs using the BMW strategy of simulating the noise.

I provided quite a bit of information already. Is there anything specific that you would like to know that I should add?
