    BMW Coding Tool 2.50
    Automatic SP-Daten Update Tool for WinKFP and NCSExpert


    • Updating of new SP-Daten files can be a pain. A lot of copy, paste and adjusting files. Manually and/or with Total Commander.
    • This tool will automatically update your Daten files for you. Only replacing the files that require replacing and skipping the files that don’t. Very easy!!
    • MSCOMCTL Error Fix:
    • For those who get an MSCOMCTL.OCX error… Please download the MSCOMCTL Error and follow the instructions
    • First, we need to set our default folders for NCSExpert, WinKFP, and EDIABAS.
    • Once all the folders are set we can now proceed to update our SP Daten. Doing this by selecting the “Select SP-source” button and then select the folder with the new SP Daten. I always like to start with the earliest model which is E36.
    • The path should look something like mine in the screenshot.
    • Now that we have set our SPDaten path we can now select the “Update SP-Daten” button.
    • Only all NEWER files will be copied from:

    Also, update of files in …\NCSEXPER\DATEN

    • You will notice the files that have been replaced will display update –> **.** and the ones that did not require updating will display remain –> **.**
    • In my case, as displayed in the image below all will show remain because I have already updated them.
    • Now repeat the same steps for WinKFP…
    • Select the “Update WinKFP” button, and all folders will be copied and replaced from:…\SP-DATEN-Exx\DATA –> …\EC-APPS\NFS\DATA
    • also update of SGIDC.AS2 in …\EC-APPS\NFS\DATA\GDATEN to adjust the “long lines.”
    • Backup’s of all folders are saved as …\name_date_time
    • Once completed… repeat the same steps for all base models so from E36 to E89. Now you have successfully updated your NCSExpert and WinKFP with latest SP-Daten files.
