Hello Guys,

A while ago I retrofitted ASD from G01 to my 2014 F30 320iX
It was flashed and coded to my the newest software and now I'm can not change the sounds, it only works with F030 and N20B20 engine coded.

If I want to code another one, for example F080 and S55B30 or F010 and S63B44 - it just getting off the ASD and the error occurs in Rheingold.

I read that it is because of the new software and I need to flash the ASD with older psdzdata.

Then I got psdzdata 3.55 and flashed the ASD.

The result was like that:


It seems to me that it did not flash it properly is I got the same problem with disabling ASD when different engine coded as well.



Could you please help what I did wrong? Is there any special procedure when you downgrade the software from newest, or it is the same as you just flash the ECU's?

Thanks!!

Please help)

The procedure of flashing downwards is the same like upwards.
You should only load the older psdzdata (before 07/2015 i think) and the program should find a different (older) software for the ASD.

I did the same procedure, but the swfl, btld and cafd files stays the same. No errors, but it seems to me that it has not been flashed

It should look like this after KIS/SVT Target calculation..
I used E-Sys 3.26 and psdzdata 15_03_502 from march 2015 for this example.

But mine is looking like that
What I did wrong?

[atzebmw]

You didn't load the older psdzdata.
At your ACSM i see a red CAFD 911_003_001_020
and the blue CAFD 911_003_001_015.
The blue is always the current software and the red is the software after the update/flashing.
But because the numbers of the red CAFD are higher than the blue one you can see that the loaded psdzdata are newer than the ecu software.
For the ASD the programm didn't find newer/older/other software. That's why there is all blue.

You have to copy/move the older psdzdata to the folder C:/Data and it must be called psdzdata without numbers or letters after it.

[Ivan887]

I already tried the older 3.55 full data as well as 2.54 full data that was placed in the D/Data without any letters or numbers

Could it be that there just no software files for ASD in this data? As you can see from my printscreen that it has data for ACSM

[atzebmw]

Yes, it may also be that there is no newer/older/other software.
But i don't know why this should happen.
Maybe you can search in your psdzdata for the files like in my picture.
These files should be found somewhere in the folders.

Thank you atzebmw, will try to search for the separate files

Here i uploaded some special Full/Lite psdzdata for you.
These psdzdata have been the full version 3.55 but i deleted every files you don't need.
I just left the files you need for flashing the ASD to an older software.
I only tested it on my home computer and not at my car.
So i can't give you a guarantee.

Thank you! Will try tomorrow and let you know!

Resolved!
I changed svt_ist file and add 328i type in FA

Success!)

Could you please reupload this? I am trying to downgrade my ASD on a 2018 435xi GC. I am particularly confused about how I can flash a single ECU and with old PSDZdata. Do I need the newer psdzdata currently on my car? and in the guide, do i still calculate for complete flash?? I assume I remove all the other columns except for ASD?

Many thanks in advance!

Maybe you can download the complete psdzdata full 3.55 yourself from here, because i don't have this special stripped down version anymore.

hey
You should only have older psdz 54 or 55 on your computer
Yes, select complete flash and put the marks only!! in ASD line

Hey just to let you know, you do not need to downgrade the ASD if you want to hear M3/M4 sounds. Its totally unnecessary!
