Hello guys!, i was reading a MB C Class 200 Compressor from 2001 whit siemens SIM4LE ECU (OBD READOUT).
That went fine, sent the file to the tuner and got it back. when i writed the file i got error, even when i write back the original flash file. the car is "dead". so the readout was only on 140 KB. so what do i do now? can i put back a original file i got from my tuner? or is it something special whit this ecus?

i will attach the the files. i readed whit genuine galletto master, and after that i desoldered the IC and used Labtool.

the file i got from the tuner who is i original and are named Winols''''''''.. etc. is it just to write that or what? adapt the ecu to car?

i will not attach the tuned file. but i know he dindt have checksum for this file.

hey I had a mercedes slk200 today with same ecu sim4le, and didnt trust writing it with galletto obd..
you seem to have had a problem writing it.. did you manage to solve it by obd or did you solder the eprom?

thanks
Marco
