Hi guys,

I have a problem with a wrong checksum. I read a file from a Mini cooper R56D 109HP 2008 with the autotuner tool, a company made it a stage 1. Try to flash it by obd and it says; checksum error. I send it back and they correct the checksum, but it still gives that error. 
Tryed it also wit Kess, but also the same error. If i do with KTAG in boot mode? Will that work, or i gone damagge the Ecu?

Thanks

Maybe the problem is in the sw you flashed.. Something wrong and checksum not computed correctly..never used autotuner but genuine kess work right with that ecu, can try with ktag but should have same issue
Send me ori and tune, I can have a look at it. Maybe they added some noread shit at the end of the file?
