This was removed from a 2009 Yamaha F90 according to what one of my mechanics wrote on the tag. Unfortunately, he failed to record the model number so I can't verify that but I believe it's programmed to a 90 and while it would work on all of the other models, it would turn your engine into an F90 with your components and this ECU.
