Greetings to all,

Is there a full read / write flashing application w/checksum correction for the BMW Siemens GS20 TCU thats used with the GM 5L40E Automatic Steptronic transmission?

I have tge MS4X and GS20 flashers but they only read/write the 64kb partial bin files. The GS20 flasher that costs $5.00 reads a full virtual file but is useless.

Cheers,

Mark
