E92 EDC ZCP Module Coding

Stirlitz wrote

Results. I have changed each dx09230 (M3+E92+!NIVEAUREG+COMPETITION_P) to active in all columns and it worked. Ride feels a bit stiffer in normal and sport, comfort is unchanged. So, it looks like car has ZCP EDC parameters right now. No errors so far, car runs good.

I just need somebody who can read their ZCP M3 EDC module software with NCS Expert and share their file.

All you have to do is code in dx09230 in every parameter in the EDC

For E90s it is dx09030.

Have you done it ??

# Competition Package EDC
The Competition Package Electronic Damping Control has revise settings compared to the standard EDC from the M3. There is mainly two differences that has been noted online.

1. 10mm shorter springs on the ZCP.
2. Revised Sport Mode to enable variable dampening instead of static 75% stiffness.

In addition, the control of the electronic damper adjustment function EDC includes a Sport mode specially developed for the Competition Package. It is said to adjust the chassis modifications by means of map-based control and the driving stability control function DSC.

##Goal
I originally wanted a ZCP M3 cause those Style 359 rims are the best rims BMW makes. The Suspension had a slight difference that probably would've made me keep the car stock in that aspect. However since rims are just rims and I read on forums of people successfully coding in their EDC to ZCP EDC, I decided to start hunting how to do this. Forums were somewhat unhelpful as most of the folks who knew offer paid services to do it.

Code my standard EDC into ZCP EDC and document it somewhere online.
The DSC portion of the ZCP package I believe is just Euro MDM. Euro MDM allows more slip angle than the US MDM. Nuff Said.

That is coded into the MK60_M3.Cxx with the follow parameters:

US_VEHICLE    Nicht_aktiv

MDYNAMIC_MODE_USA    Nicht_aktiv

M3_UEBERSTUEUERN_MUE_0    wert_00

M3_UEBERSTUEUERN_MUE_1_2    wert_00

### The Research
With the help of NCSDummy, I opened up the DATEN File for EDCK65.C1A to see input values and their corresponding data values.

Short description:
dx9023 = Non-ZCP E90 with EDC
dx9030 = ZCP E90 (EDC is standard)





As shown above, the options row shows the requirements to meet in order to use that value as default. An exclamation mark means negate in this situation. The Data row is the output to the module and in this parameter, they are identical. This means this parameter doesn't care if you are a ZCP or non-ZCP, you are getting this value no matter what.

However, in the below one they are different data values of C8 and A0. What these actual values mean is beyond me. However, this helps conclude my research to a specific finding.





### Proposed coding

Code every parameter to dx09030 should apply all the values from a ZCP to my EDC module. I suppose you don't have to do every parameter as some of them offer the same data value but it is faster(lazier) to just code dx09030 all the way through.

I'm pretty sure this will work as most people suggest feeling revised settings after coding in the ZCP values. However since they either didn't know what they were coding or someone did it for them, I am not 100% sure this will work. (99% maybe.)

Good to know if I ever remove my coilovers and go back to EDC. I have a set of ZCP springs. I always thought the physical shocks/struts were different.

Would writing the zcp option code to the VO and then default coding the EDC ecu achieve the same results?
