Did I understand this whole thing only affects a select number of 2006's? I haven't followed all of the threads on this, but I thought that's what I got out of what I did read. When I searched awhile back, I saw the letter WC got ahold of from Yamaha that listed the VIN range. Am I on target here?
Changing out the ECU has nothing to do with mileage, and some are making a bigger deal of the swap than is really necessary. The problem with the pre-swap ECU was that it adjusted for altitude every time the throttle was moved 1/4 turn. If someone had a significant elevation change without moving the throttle the required 1/4 turn, the bike would show some type of adverse effect from the wrong air/fuel mixture. All the ECU swap does is lessen the turn requirement from 1/4 turn to something like 1/8 turn. Really, unless someone was riding up into the mountians with a throttle lock on, I find it hard to believe the throttle was not moved 1/4 turn and the computer was not readjusted. I only got mine changed becasue I LIVE in the mountians. I never had a problem and wonder if I ever would have. Your 2008 should have come with the new ECU, so the recall did not affect your bike.
FJRP just saw this and know its a late response but, the VIN's listed in the letter WC posted up were the bikes affected by the ECU problem from Yamaha. 2006 and 2007 models were affected only and from my weak memory more 07's were affected and more severly than the 06's but both had the problem. The correct thing to do is check to make sure your 2006 to 2007 bike was on the list and then the bike owner needs to contact their dealer or any dealer and schedule your bike for the swap. Your dealer or Yamaha will not call the owner on this. If they did consider yourself lucky. I got a letter from Yamaha on this as did many owner's but if you didn't get a letter doesn't mean your not affected. From my VIN my bike is one of the early production 2006 models and it's on the list.
