Looking at the popular CS coding that is going around, there are actually very few changes so thought i would post them here for those that are inclined to do themselves. This was generated from US-Spec m3 comp xdrive (Type Code 43AY) > US-spec M3 CS (Type Code 63AY)

Steering - 3 params

VehicleVariantStF3Value: STF_169 (00,A9) -> STF_185 (00,B9)

DSC/MDM - 4 params

Transmission - the CS transmission is a flash, you need eSys and full PSDZdata and you can flash it. i guess if you already know how to do that, you don't need this info

Suspension - Not sure about this one, the CS has different dampers and springs, there is no reason to expect that using the CS-specific suspension tuning would be an improvement on the comp hardware. Feedback i have heard is running the CS suspension coding on the comp hardware makes the suspension softer.


This is all the changes that i can see. There are no changes in the differential module. Hopefully needless to say, take backups, i'm not responsible for you messing up your car should you try these codings.

Anyone has any other info, please add.

So do you need a separate file in addition to the above to flash the transmission?

<-- Knows zero about coding.

Yes. Two things… the eSys software and then the pack for it that has the flashes for the modules/ECUs in question.
