Hey guys, the ECU is screwed to the bottom of the plastic tray that holds the tool kit, under the rider's seat.
I already pulled mine, and will try to just exchange it with dealer, but if they insist to bring the bike in, I'll just hook up the ECU, wrap it in a rag, and install the seat. Bike is fully operational this way, as air filter is in place, and nothing else has to be disconnected. This way, it should take less than a minute to swap it, even for an incompetent tech.
To remove that tray, you need to do the following:
- remove left upper panel (the one with 'FJR')
- remove black cover in front of ECU (2 push-pins and a screw on the left side)
- remove 3 screws on top of the plastic housing (1 under tool kit, 2 on back, behind cross-member)
- remove rider's seat latch mechanism (2 10mm nuts). Requires some wiggling.
- disconnect ECU.
- push tray up in front, then slide towards the tank while lifting it up. The tabs where the rear screws mount will wedge themselves in 2 dips there, so just push them up with your fingers from behind the cross member. Cover will easily get removed after that.
- unscrew the ECU ( 2 screws) and you're in business.
If you need to take bike to dealer, you only need to reinstall the ECU (remember to use a rag to dampen vibration) and rider's seat. Finish the job once home with the new ECU.
I'm waiting for mine to arrive at any time, and have my ECU in my trunk. Will try to just exchange it first, or do what I described above. Hope this helps folks, and good luck.
