My DCT conversion to M3 GWS/FLASH
- Thread starter dyezak
- Start date
Nice deal. If you're going to run the 2.56 for a little while first, please log and maybe let's try some changes in the tune or even a stock flash first? I haven't seen anything in the DME rom specific to a DKG. Ironically, the 16 bytes next to the MT FD ratio in INA0S works out to 2.558, but is something else. I haven't seen any FD ratio setting in the DME for ATs either. Doesn't mean it's not there, but guessing it will be something in the DSC and/or TCU bins for AT/DCT. If anyone can find it though, it will be Jake.
This discussion regarding the diff ratio is my main concern with the retrofit. If there were no issues with downshifting, I'd have the install finished this weekend but as it stands it doesn't seem like something I will go forward with. Installing an M3 rear end into my car is not a consideration due to money and insane amount of work. 
This community is beyond amazing with the support and documenting of projects like this. I really commend the effort.
Looking forward to any possible diff ratio solutions other than a full rear end swap! Jake!!!!

My downshifts are perfect
After I changed the VO I default coded CIC, JBBF, DSC and Kombi
Just need to get the shift lights working
After about a hundred miles my shifts are butter smooth. Seems like there’s an adaptation table somewhere.
Oh shit. Really? So there are no issues at this point with the 2.56 and M3 GTS ZB?!
WELL THEN. I will also be attempting this install thanks to the incredible guide!

OMG this is awesome! Anyone able to confirm no up shift at redline in manual mode? Searching for M3 GWS right now.
Let me throw this up here, it may save someone a little grief. Helping a guy with remote coding for the shifter swap, did VO changes, default CIC, KOMBI, JBBF, CAS, DSC, etc. and specific KOMBI and CIC coding. He was getting DSC related errors, start up assist warning on a MK60_87.C0F module. Looks like, at least in this instance, that C0F_GETRIEBE (transmission) defaults to wert_00 which is a manual and it needs to be wert_02 for DOPPEL_KUPPEL (DCT) and for good measure I disabled start up assist (not even a option in a M3 DSC module) C0F_HSA. Errors gone.
Input like this is invaluable for compiling comprehensive guides later on. Usually this information gets horded and forgotten.
Not that I know of. I'm trying to get some module dumps right now. And I've found a lot of M specific values in Dummy for various parameters that may or may not play into it. Dropping off my driveshaft tomorrow to get shortened.Forgot to ask, did the CIC MDrive coding work? Haven’t seen anyone make it work yet...
Feel free to add screenshots to the MDrive thread
I wonder why some modules will just take the correct modules from VO and others don’t. The only thing I can think of is that they actually need ZBs that are m specific... maybe that’s it ?
I still think that M drive settings get stored in JB FRM or CIC
