its possible. FTECU knows hows. im running that config on my bike, but didnt install it so I don't know much more.
Get the wiring diagram, I don’t have it handy. I just got done doing a diagram wiring a 14 R6 to Motec CDL3, bit of a pain to do that clean but it will be.
I remember seeing a while back a tutorial about pins to swap to use a yec ecu with a stock harness and it had instructions for US & EUROPE bikes. Just don't remember what it was and if it would just be to reverse that. No sure if the actual yec harness has something different.
