I have e39 siemens ms41.. i made immo off. Car starts. No problem. But checksum is wrong. Because of that dme throws an error. Like 'dme self test error'

Could u pls fix the checksum?

I m sending u original and immo off version files.. 

Thanks

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.
