Anyone tried M5 Competition/30 jahre flashing and Coding?

A friend of mine convince me that the Steering, Adaptive Dampers, E-diff, and DSC (MDM) on M5 CP are a lot better compared to the ordinary M5 with relatively same hardware.

Out of curiosity, i tried to VO code my friend's car by adding:
1. S7MAA (Competition Package)
2. P7MNA ( M Competition Package)
3. and changing his build date to 1214, since CP cars are out within early '14 right?

to his VO, since there's no specific typeschlussel for M5 CP.

then i VO code the
1. Servotronic module (for the steering)
2. VDC Module (for the adaptive dampers)
4. DSC

all done without errors arised. except for the VDC that needs to be re-calibrated, as usual after flashing/coding VDC module.

That being said and done, my friend and i are out to test the car, but he said that he didnt feel any difference.

Has anyone tried this and can give me your honest opinion about this?
i did a mistake tho, i didnt compare the SWFL or even CAFD of the standard vs the coded one. maybe you guys that's experienced on this can clarify better.

Thank You

Using Tokenmaster's NCD tool, I simulate with the SVT-CAFD function adding 7MA and I get the following changes listed:

<<< CAFD_000006C6.caf.003_003_003  (VDC1_01) >>>
VDC1_01 > AUSSTATTUNGEN 3001 > M_Competition / High = aktiv 
VDC1_01 > FAHRZEUGVARIANTE 3000 > Fahrzeugtyp = alle anderen [Default]

<<< CAFD_000007C3.caf.015_001_001  (GHAS01) >>>
GHAS01 > DataSetSelector 3000 > DSS IPM = Not Supported [Default]
GHAS01 > DataSetSelector 3000 > DSS TASC = Not Supported [Default]

<<< CAFD_00000F9B.caf.001_016_000  (ASD01) >>>
ASD01 > ASD-Configuration 3000 > Competition Paket = Yes 

<<< CAFD_00000B52.caf.003_000_002  (DSC_CT01M) >>>
DSC_CT01M > DSC_CODIERDATEN_ALLGEMEIN 3000 > C_Variante_Fahrzeug_e = F10M5_BST1303 [Default]
Note that the GHAS values are completely wrong, since it doesn't show the actual specific F10M5CP values there that my '14 CP car does have. The tool only provides a guestimate it seems, plus it seems unable to predict changes necessary to REMOVE a feature. Also note that no DME values are shown. I suspect DME is entirely firmware dependent (different file loaded rather than just some different data values).

I can't really weigh in on whether this is going to do anything if the actual hardware involved is different and you don't have it.

What I can say is that unless your ECUs have been reflashed with firmware I-Step which is from within the CP package production range, most likely all the ECUs in question don't have any of the data tables within them for CP so coding them to select those tables (that's what most of the above coding is about) wouldn't get you anything. ECU's installed before the CP was released probably do not contain any CP specific data. You could have problems depending on what it does as a fallback if you tell it to use tables that don't exist.

You could check the above coding parameters and see what values actually got set by your VO coding and see if it actually even allowed you to set those.
