Just curious to whoever have tried all 4.

I have tried ZB 7845773, 7848442, 7847868 and 7847869. My car is an Australian Spec M3. I have not tried the US DCT tune as I am in Australia.

I have just tried 7847869 and I'm not 100% sure it is actually Euro DCT Tune because Australian Spec M3 comes with 7847868 (latest update) and it starts in D2 (similar to GTS & CRT DCT Tune) however 7847869 starts in S3 for some reasons.

I don't understand the noise difference as well between 7847869 and 7848442 as they sound the same to me (although some of you believe the noise from 7847869 is more mechanical and rewarding to hear).

I believe 7848442 is less clunky out of all the DCT Tune and rev match better.
