RE: BMW E39 MS41 IMMO Off Checksum Required
cant check right now. Anyway for example kess will calculate checksum itself. How ever use WinOLS for that. Its quite easy to calculate.
Checked - u did it with UID probably which is wrong. Try this.

AD: just rename the file .bin instead .rar its not archived actualy! Im doing it on PC at work so dont have winrar xD

Here is proper imooff... 

newer disable the imo is ms41 by FFing first strings of calibs, you killing control bytes..

and you don`t need to desolder 28f200, all can be done with galetto 1260. Don't forget to put +12 into 18 pin of diagnostic connector while programming.
