But I am still eager to read feedback from folks that will code the CP ASD on their cars.

I have MPE on my inbound M3 and plan on coding this to try it out. Will let you know my thoughts.

I installed the Dinan exhaust a couple weeks ago. It sounds good - granted, it's not as loud as other aftermarket exhausts I've seen/heard on YouTube. I unplugged the ASD module and drove it around for a day and I personally prefer the sound from ASD. I plugged it back in and for me, it enrichens the driving experience. My two cents.

So if I have a MY 2016 September built car, I should be able to code ASD CP to ON? How many people have done this so far?

Guleb has done this and reported on the difference it made in post #17. The question is whether the new ASD unit is needed to fully get the intended sound.

We will have to wait until somebody with a March 2016 build tries it.

• There are firmware changes in the ASD ECU between my build and current-production cars: my car has SWFL_0000111D_002_007_004 and SWFL_000021D4_001_009_001, while current-production cars have SWFL_0000111D_002_007_006 and SWFL_00003EE0_001_004_000.

Hmmm.... my car was apparently built on 2014-07-03 and I doubt it's ever had an ASD firmware upgrade. I'm also guessing that the original firmware knows nothing about CP coding values.

Assuming the hardware is compatible, would it be possible to DIY update the firmware?

(From my limited understanding of coding, I'm thinking this would at least require the full pszData so maybe something I need to convince a friendly dealer to do for me - just like the HUD update I never managed to get )

You could check if your CAFD shows the "Competition Paket" parameter and whether that makes a difference (I have not had a chance to try on my car yet). At most, if it turns out that the new ASD hardware is not critical, it will indeed be a matter of flashing the ASD ECU (just like doing the HUD update).

I've coded CP to yes on my car during some experimentation but only to check if faults are generated in Rheingold which was the case. However I never did drive to compare as I don't care about ASD you can flash ASD, and should be a simple procedure as its a very simple ECU compared to others. Here's a thread where few people did it http://f80.bimmerpost.com/forums/sho....php?t=1193651

You coded CP to Yes in just the ASD, or other modules? Did the Rheingold faults occur after just coding the ASD?

When I was experimenting back then, I coded CP only in ASD, the fault is thrown for all of us that have coded ASD off, it's no big deal

[7woodman7]

my car is 02/2015. i have the CP switch under ASD. tried it out and been not able to hear a big difference.

[Chayse]

This is all very interesting. I have been following a lot of the threads for Coding items on my car. I like what I am hearing regarding this, but I have a very old car. It is a 2015 with a 6/2014 in service date. dmnc02 if you would like to meet up and grab some files from my car, I would be happy to help.

[Bluex]

Will be following this with interest.

I have a 4/2015 production date and have not updated my ESYS software or psdzdata since I did all of my LED coding.

[terahertz]

Perfect! I had the idea to do this once I heard the CP was released. Hope to see what you guys find can be coded.

[momo3605]

How come this wasn't discovered until now? If this is codeable on a post July 2015 build F8x, why wasn't it discovered then when the MY16 cars came out? Do you need new software that was just released recently to code this?

I didn't know about the other Fahrzeugtyp option. Either that has to be coded at the same time, or maybe the comp pack stuff wasn't implemented in my version of software on the car, and my car is pretty new.

I have ASD disabled, so I wasn't interested in that.

I will be trying these settings this weekend maybe. I also downloaded the 58.0 PZSData, so I could possibly upgrade some modules if needed.

Does anybody know which module controls the rear diff? Is that perhaps part of the ICM or VDC?

I think it's GHAS.

My build was Nov 2015 and I needed 57.2 to code. 57.1 didn't work.

Hmm. I haven't looked at that module yet. The official Comp Pack description says "Reconfigured Active M Differential", so I was expecting a coding change to whatever module, but perhaps the GHAS has a different firmware loaded on it instead of using coding to switch profiles?

Edit: Great info in that document.

"The signals of the Integrated Chassis Management (ICM) and the Dynamic Stability Control (DSC) interact functionally for the distribution of the locking torque at the rear axle."

So maybe coding the ICM and DSC are enough since they seem to control the lockup of the GHAS.

[aboulfad]

terahertz, there is a new GHAS SWFL & CAFD version update between my car (06/15, psdZ 55.3, F020-15-03-503) and current production (psdZ 58.0, F020-16-03-501), but it looks to be a minor one, but who really knows for sure what these updates do

I finally found time to experiment with this. Despite the 7/14 build date, E-Sys did show the Competition Paket parameter, and allowed me to code it to 'Yes'

I took the car for a drive, and my first impression was that it was *much* quieter in all modes - almost as though ASD was disabled.

I *think* there was still some synthetic sound, but it was barely noticeable. The bass grumble under acceleration and the diesel-like idle sounds were almost completely gone. Under hard acceleration, maybe a bit more E46-like.

Not very much difference between comfort and sport/sport plus either. In fact, the car sounded much too quiet until I set the exhaust valves to 'always open'.

So, I'm wondering if somehow due to old firmware I effectively disabled ASD?

I recall but not entirely sure that when setting the CP ASD param to yes, that Rheingold reported a similar fault as when we set the car type to anything but F08x to disable ASD. So it's possible on cars not equipped with new ASD module, that setting that parameter won't do much, but maybe also disable ASD as it throws a fault. But again I am going from memory, can't recall for sure from my earlier experiments (my car is 06/15).

Where can i get E-Sys ?
