BMW E46 SMG Coding with BMW ICOM WinKFP software
Here is an example of coding BMW E46 M3 (with SMG2 transmission) Euro SMG mode also called “CSL Coding” with BMW ICOM engineering and developing WinKFP coding software.
BMW ICOM ISTA/D ISTA/P with WinKFP 5.1.6 or newer version software HDD and 46 data files
BMW ICOM A2+B+C diagnostic and programming tool
Stable power supply 13-14V at 10A (very important)

Copy the contents of the sgdat folder to C:/EC-APPS/NFS/SGDAT
Run WinKFP software again
Turn ignition ON

Turn ignition ON after 5 minutes. Clear the stored DTCs in control module with BMW INPA software.
Turn the ignition off and wait a few minutes again if the transmission error light is still on.
Start the engine and enjoy the improved shifts. You may need to run the SMG adaptation procedures.
The whole procedure takes about 15 to 30 minutes. Do not exit the software program or disconnect the BMW ICOM diagnostic tool with vehicle, otherwise, the SMG module will be bricked.
