ecu reset
« on: September 30, 2016, 11:10:20 PM »
Has anyone  seen/read  this  ???????? ;


 Resetting the ECU

      Apparently as part of the prep before the dealer hands over the keys, the mechanic resets the ECU starts the bike and lets it idle for around 15 minutes until the fan cuts in. In the 15 minutes the ECU creates a base  map                using all the info gathered from the O2, water temperature and possibly other sensors.

     Smoother throttle response, pulls from much lower in the rev band in all gears and 6th is much more usable. Also seems to sound better.

     This is what I did.
    1.Completely disconnected the battery for 24h (my reading sources state 10 minutes to half an hour) I wanted to me sure.
    2.Turn the key to on to get rid of any held power for about 30 seconds (probable not needed).
    3.Reconnect Battery (make sure all other electrics are off)
    4.Turn key to on
    5.Start bike without touching the throttle.
    6.Leave to idle (DO NOT TOUCH THE THROTTLE) for around 15 minutes until the fan kicks in (mine took 16 minutes).
    7.Hit the kill switch.
    8.Turn off the ignition.
    9.Now you’re done.

    If you do decide to give it a go please let me know what you think. Found this on a forum for the Honda Goldwing 1800 and a few other bikes.

This sounds awesome :thumbs, at the moment I can't even use 6th gear (It's like I don't even have one ;-* :rofl)

But on a serious note, this sounds like something that may be worth giving a go, thanks for sharing :thumbsup

Does anyone know if the ST1300 ECU is an "Adaptive ECU"?

If the ECU IS an Adaptive ECU, I can see the benefits of carrying out the above procedure.

If the ECU is NOT and Adaptive ECU, I'm not sure if the above procedure will result in any benefit!

I have carried out a similar procedure on a number of different bikes as well as cars.

 :blu13 Yes Draco has completed this today (afternoon) I did as was instructed (BUT left it disconnected for 3hrs only) longest 3 hours EVER  :well :well. reconnected, started (no throttle) allowed to idle 15 minutes fans came on a few seconds after 15, then donned my protective gear :cop :law and went for a short ride (over Clear Mountain) in the streets first and second had noticeably increased in pulling power, the throttle was smoother than before. As far as fuel difference I am now getting 24.7 kilometres per litre in 5th gear at 100kph....so Draco is one happy chap :runyay :hatwave :thumbs :blu13left

"24.7 kilometres per litre in 5th gear at 100kph"

That's an extraordinary economy.  I think we'll be reading a lot of reports of ECU reboots.

Will give this a try tomorrow. Had my  :blu13 for nine years now which returns me 18km/ltr or 5.6 ltr per 100k. What's the worst that can happen? Will be next weekend before I can give it a run. Will report back in the future. Could become the 'start up' routine after a battery change.

Tried this today but no luck ☹️️. Left battery disconnected overnight, turned ignition on(battery disconnected) turned ignition off, reconnected battery, tried starting but just wouldn't idle without throttle input, misses and stalls :'(  managed to get it to idle after lot of throttle twisting and warming up. Now seems to be running very rough. Prior to disconnecting battery was idling and running perfectly. Is it possible there may have been some issues for which the ECU was compensating but now that the ECU has been reset the problem is showing up? Any ideas would be greatly appreciated.

It sounds like the reason it isn't running right now is because the throttle was moved during the 15 minute remapping stage.

I would suggest disconnecting the battery, waiting 30 minutes, then reconnecting the battery again and see if it will idle without touching the throttle while the remaining takes place.

Thanks Brother Shiney, throttle wasn't touched, just wouldn't idle. Disconnected battery for half hour, tried again, same thing, won't idle without throttle, just stalls☹️

You might have to play with the idle screw to get it to idle properly instead of touching the throttle (if you do I would suggest doing the remapping again afterwards)

Unfortunately that is about it for ideas from me but I'm sure someone else will have some other ideas :thumbs

Hmmm.  Maybe the ECU reset is a risky endeavour, not to be undertaken if the bike is doing alright.

Can't see why  disconnecting battery should have caused any problems, Unless there were issues which decided to manifest after ECU reset.🤓 Anyway had a great ride on the XS1100, will tackle the ST cup day🤓

Started her up this morning, and everything seems back to normal, idling ok, no missing. Been going through some earlier posts Re: 5 way connector, will give that a clean out and change spark plugs tomorrow then try ECU reset again. Will report back on outcome 🤓

Couldn't wait until tomorrow 🤓 So got stuck into it as soon as I got back from work. Pulled out the 5 way connector which was partially blocked, cleaned and refit. New plugs unavailable so sandblasted old plugs, washed in petrol and regapped, refit everything, performed ECU reset as per instructions, now purring like a kitten  :like . Idle rpm was a bit high, 1100, reset idle to just under 1000 rpm now just need to take her for a ride tomorrow.
Thanks Lonerider for original post, and thanks Draco  :thumbsup. Me happy now🤓
