Ecutek have written extra bits of data into the "stock" rom in areas that are just padding or spare space ie ""FF".
This may be for various reasons, but likely to be so that ecutek can identify the ROM as one of theirs for licensing/locking tune ect or that Ecutek has written to this ROM/vehicle at some stage.
Ecutek can also add extra features to their ROM's (RaceROM's (not this one as its a "stock" ROM), to do this they patch the original ROM's instruction code with extra code (program instructions) to perform extra functions such a map switching. this extra code need's to be inserted in "spare" or unused spade in the ROM usually this will be filled with "FF". The extra code data for alternate maps ect is usually inserted in this unused space. These ROM's are also locked/encrypted such that an ECUTEK licence is required to access/flash the ROM's I believe not even dealers can access/flash ecutek locked ROM's
Well that the way i think it works anyway.
