Insist on getting the updated ECU. I had the same issue and the conversation with the dealer started off with "well, they all do that..." Yeah, right! If this update has not been done, it's certainly worth fighting for it. After a bit of prompting, my dealer finally ordered the part. I dropped my bike off in the morning, used their loaner bike to run a few erands, went out for lunch, and my bike was ready to ride home in the early afternoon. Problem solved, and a huge difference at idle and when cracking the throttle after cold start up.
