Flash tuned file with winkfp

Hello. I am new to this forum and this will be my first post.
Regarding the topic, flashing modified sp-daten file to the dme with winkfp.
I doubt this is possible with success. I have looked alot to this possibility in the last months. I have even been in contact with EVC in Germany regarding this since I already have a fully licensed WinOLS. It is correct that WinOLS recognise these files, but the problem are the checksum calculation. I have several checksums plug-ins in my WinOLS, and when I open a file which I have the correct chk.sum plug-in to, it recognise the file, but says that the chk.sum are incorrect and want to correct it even though it obviously are correct. The winkfp program can be configurated to not test the checksum, and I assume it will actually make the programming, but as I say, I doubt it will be success in make the engine start. I know that WinOLS have plug-ins for correcting checksum in update-files from manufacturer to Jaguar/Ford/Volvo, and such plug-in could be nice to have also for BMW. See link from EVC.
