I've found differences between ECU dumps from the interwebz that supposedly belong to the same EDC15C2 version of both HW and SW. Sometimes, it's just a handful of addresses. Other times, it's more than fifty... And they are all located near the end of the file, past the second bank of maps.
Out of curiosity... Does anyone know what are these? Odometer data makes sense for the fewer spots. But what about larger chunks of data? Different equipment? Immobiliser?
Just trying to make some sense of it all.
