Wrong checksum.

[ecuconnection]

The tuned file does not even match the Ori ... totally different software

Yeah, I wanted to say same, but I couldn't be sure, since I'm newbie in tuning. So, I had right.

Wrong checksum.

MS41 with wrong checksum calculation allow start engine

[ipejasinovic]

Dunno that, but since cs was wrong, I thought that is problem. But, looking trough ori & tuned maps, I had feeling like this aren't same maps.

WRONG!! ECU will lock up

The tuned file is wrong version... Perhaps a euro vs USA/Can model

i get tuned file with same siemens numbers as original,now check it,yes it is different...

can somebody tune original file for me or disable rpm limiter?

Hey mate,
first... shutt off your CAPS key before to tell me that i am wrong.
2nd... from original file do somes variations into maps area (fuel, ignition etc) and put ecu without chk correction and after tell me.

MS41 cannot be flashed without checksumm correction via software or built in checksumm correction in the flash tool software... If you are using a clone and you flash with mistake you will need to desolder the chip unless you have a real tool and can recover it

Who has talked about k-line flash programming????,
I use winols, digiview cmd FR tool and somes other tools that maybe you don`t know, every original as like the law tell.
We are talking about chk correction no flash programming with basical flash tools, maybe your cloned tools have yet locked any ecu done for you, perphas?
