Re: Siemens Simtec help greatly appreciated
Here´s a solution for the checksum
Don´t hassle with integrating the checksum, its only possible after disassembling the code with IDApro and i think we aren´t at that point currently.

Re: Siemens Simtec help greatly appreciated
Building an xdf is all hard hand-work. Simply type in all maps, scalars, axis descriptors etc.

Re: Siemens Simtec help greatly appreciated
Having a short look at your file, it turns out its pretty much the same structure as Siemens MS43 and MS42 :mrgreen: This is what the guys at Siemens MS41 are using to find the correlation, but either i´m not clever enough to work it out at MS43 or its just not working at newer ecus. Maybe you guys...

Having a short look at your file, it turns out its pretty much the same structure as Siemens MS43 and MS42 :mrgreen: The axis definitions are separated in the first part of that file and are pretty easy to find. However, the correlation to the maps isn´t easy and maybe only possible by disassembling...
