Hard Starting at Altitude

When the bike is hot and I try to re-start ti above 9,000 ft I have a hard time getting the bike to start. Does anyone know if the new software will fix this mixture issue? Almost ran out of battery juice yesterday...

In Germany's most popular motorcycle magazine "Motorrad" they found out about that issue, too. They said that Ducati knows about that problem and will fix it via a software update. They didn't mention whether it was released already, the magazine issue was like 1 - 2 months old.

I havent seen this problem, we spent a long weekend a while back at 8500 feet and the bike ran and started as advertised, I wonder if 9K is the magic number.

Well I have had this issue, knew about it in the back of my mind and was prepared for it. Over the weekend while traversing Boreas Pass I stalled it and then it was reluctant to start so using two hands one for the start button and the other on the throttle with just the tiniest amount of fuel while cranking it, it started. That was over 11K feet The next time was when was on Guanella Pass when I stopped for a photo opportunity around 10,200 feet or 10,300 and it was a bugger to start using the same start procedure. The bike has the same software installed at delivery.

I wonder if the SC Project exhaust with adjustable fuel controller would cure this problem, I'm thinking of ordering this exhaust system.
Obviously Ducati need to look into this and come up with a solution, bike must run very lean.

It behaves the same as if its flooded. If you are patient after a stall, roughly 5 minutes It will start. If you treat it like its flooded it will also start. If it stalls at altitude you might want to cycle the key versus leave it on and try and crank. It probably helps the ECU reset pressure.

Seems like you might just be reaching limits of the FI/ECUs start-up auto mixture cycle. How does it idle at this altitude?

FYI, apparently there is a re-flash out for the starting at altitude issue, contact your dealer.
This is an extract from a thread on the Ducati.ms site

'They did an ECU update saying it was for high elevation starting.'

2013 HyperMotard stalling, but idles OK - Page 2 - Ducati.ms - The Ultimate Ducati Forum


BTW. this is the ultimate ducati hyperstrada website ;-)

It idles just fine and when starting it does act like its flooded.

I didnt cycle the key will have to try that this weekend.

No plans as of yet to hit the stealer for a softwear up date....
