EsysX or Esys How to add specific parameters ??

[fpgiuliano]

Hello everyone,
I'm trying to code my BMW G20 with e-sys X, but the code involves the insertion of a specific parameter that is not in the list of the “EDIT FDL”.  
Specifically I should enter 0XFFFFFF .

it seems it needs fsc , but i have no idea what it is... i tried to search on forum or google , but i could not find anything.  

can anyone help me?

Thanks
