I've downloaded the rom from a 06 EUDM WRX but I can't see any table in Ecuflash. Actually it seems there's no xml file for this particular rom (A8DK100Y).
I wonder if I could use another XML file and rename it as A8DK100Y.xml or specifying in ecuflash that I wanna read this rom using another xml file.
I would not recommend that. This rom is going to be added to the next xml definition update for Enginuity, so you'll be able to tune with it when it's released.
