THANKS A LOT!!!

That was the solution for the problem.
It is not only using a US XP, it is also using the US Formats for comma and point! German numbers have a different format...
Yes, in the "0" cells is written "0,00" what is not usable for your software, it must be "0.00"
And this is also the difference between a 153 ECU file and a 173 ECU file.
In the 153 ECU File the cells are filled with integer numbers like "25".
In the 173 ECU File the cells are filled wit number like "4.25"
This was also the problem when i filled the 173 test file with the ignition tables of the 153 ECU. Filled with integer numbers it worked for a while, but restarting with german XP numbers formats it killed the data set.
OK, PROBLEM SOLVED!
