I would love to get .dbc file for MY 2015 Subaru WRX STIShould also note, earlier models use single CAN lines between some modules.
For example 07 Imprezas use an HS CAN line between the ECU and DCCD Controller as well as the ABS unit,
06-08 Foresters have one from the ECU to the ABS unit.
I've got a .dbc (or whichever database file format you like) going for the Subaru chassis' that is always growing, so CAN IDs are super easy to get around.
Same with immobilizers.
