as I said for me its no problem to change werte for FF (active) or 01 if its show UnknownParams

Correct, I have never said it cannot be coded.  I too could change the values and write the code.  

The problem for me and the risk I did not want to take was the fact that the entry I was looking to modify was being shown as UnkownParmeter, so EsysPlus does not having it mapped properly to the matching 11/21 PSdZData.

Also the default werte value I read from my car for one section I was concerned with was 00 in that UnkownParam value.  If I use the CAF viewer and open the CAFD file EsysPlus is mapping against in PSdZData with "Fix by Reference" the default value shown is 02.  So this concerns me as I know my car "should" currently have that section with a default value.

And just to reiterate, I know, I know... it can be coded and others have been successful letting EsysPlus do its "Fix by Reference" mapping.   But for me I don't feel its worth the risk of potentially bonking an ECU or applying/replacing values for ECU sections that I don't want to accidentally change.   So I am going to wait for EsysPlus to support 11/21 before I try to modify my SAS3.

Thanks a TON to Masa52 helping me get to the bottom of this.

I have the same problem. the "Fix by reference" fix wrong.
The mapping file is wrong and if you use the fixed you modify random fdl.
