It's not that hard to use the search button when it comes to finding proper definitions for this exact ECU, its been days since I started searching over forums, believe me
I found the xdf you linked before but it does not contain all the definitions. I have the ori bin comparing to modified one (by tuner) and can not find all the modifications, struggling with lots of "item not defined" alerts (see attachment). I am trying to adjust some maps to get fueling right (a lot of weird lambda controller behavior).
I will try to combine those two xdfs into one hoping to get satisfying results.
It's been a tough way, my tuner stopped helping with this case, there has been a lot of work done so I am willing to get the car going properly.
