just try the different sizes in nefmoto software would be a self-solution
or
just google the part number of your ecu and find nefmoto posts with 1024kb filesize = 800bb
or
take the sticker off
or
just know that this is a very modern and late me7.5 which means 1024kb = 800bb
some of the 800xx will work
Thanks have tried, looks like it's on the cusp and too new maybe.

I guess the real question is.... Can I use an 8E0 909 018 to repalce this ECU ?
