ECU Removal + Stripped hex bolt

Hey all - finally coming around to reflashing my ECU. Was wondering if there were any videos lying around of people doing it themselves? To complicate matters I'm pretty sure I stripped the hex bolt that attaches the seat to the frame. I've been putting off these mod for a while and now that I have the time and cash I've hit another roadblock. Any suggestions are welcome - should I use a drill gun to remove the bolt?

Quit while you’re ahead. Bring it to a professional.

I agree with Burke. Don't borrow a drill gun to remove the bolt. Use one of these.

Thumbs up

If you aren't experienced I'd have someone give you a hand or take it to a shop. If you feel adventurous (tinkering is one of the best parts of owning a bike) then you could drill a pilot hole into the head of the stripped bolt and then use a bolt extractor bit to reverse it out. Best of luck.

I looked into a DIY tutorial for flashing the ECU from home as well but came up short. For one, you need special software, a special plug, and lastly you need to know which line of code you're messing with in order to achieve a desirable result. Sure, you might be able to navigate around if you somehow transferred the file(s) to your PC, got the file to open in Notepad++ and poked around, but the threat of burning out your starter, blowing up a valve because of too much compression, or drowning your engine in gas because of an extra value or misplaced #, x, 1, or % symbol is too risky.

Trial and error on a $7,000 item is where I draw the line on experimentation, and I stopped looking when I came up short on finding anything useful online anyway. Best bet is just to send it in once you take care of that stripped bolt. I feel your pain this: Mine's almost stripped from taking the seat on and off so many times to take measurements for the underseat storage tote I now make, and the other electronics I wired into the system (accent lights, full LED conversion, and heated grips). Now I won't dare to take the seat off until I get my @ss to the hardware store for a replacement bolt, or come up with an easy quick-release system.

Best of luck!

Ha - the way I read the OP, I thought he wanted help with simply removing the ECU.....not actually flashing it himself!

@Krixtoph really appreciated the response! No I am not doing the reflashing myself, I'm sending that to Ivan.

Once you get the stripped bolt sorted out, consider making this simple modification. It was well worth it, and simplifies seat removal because you only need to loosen the screw a few turns instead of removing it and dropping the screw into the abyss under the seat. And with the right tools you can do this right thru the oval slot in your side cover instead removing your side cover to access the screw.
