Surging

gatdammit · Apr 23, 2014

Alright, Zippy. This can easily get ugly but my point is: I don't want anything on my bike that I can legally remove and was only hung there at a cost to the consumer because 1 state has entirely too much influence.

And I've lived in SoCal. Twice. Kept my Florida residency. I personally like how the community of Coronado would like to evict the Navy, even though Coronado only exists because the Navy built an airfield on that patch of mud they consider theirs.

We can continue this offline but I won't respond to it any further in the open forums.

I certainly do not want to offer any political opinion at this point, but it's worth being aware that thirteen additional states have adopted the equivalent California standards, with the EPA applying those standards nationwide in 2016.

I had exactly this problem Nate. It was only at 6000 rpm, perhaps 100 either side, and only in 6th gear. I had all the latest ECU updates done at a service last week and the throttle is totally different. I previously really disliked the throttle, very hard to ride smoothly in any setting. The update has completely changed the riding experience so get this done and re *****. I came he cross country so I've not tested the 6th gear issue yet. I'll let you know.

I have the same problem by 6000 rpm, I will check next week with the Dealer if i Need ECU update!

ECU update has fixed this issue

Hi Nate,

I went out on a 200 mile day ride yesterday and I can confirm the 6000 rpm issue has been fixed. The whole throttle experience has been massively improved. At 30mph the option used to be a jerky ride in 2nd gear of a lumpy ride in 3rd. Now the bike sits at 30mph without any snatching in either gear, even 4th if you wish, and is a joy to ride in town.

The ECU upgrade has completely transformed the bike for me, it'sa must do upgrade!

Enjoy, Alan

Well I have same problem. And mine is an European Hyperstrada

Hi, new to the forum and have a 2013 model. Issue of surging appears well documented and acknowledged by Ducati yet not successfully resolved. (I note they released a monster with the 821 on the weekend). So just wondering if anyone has either (I) added an aftermarket solution or (ii) specifically written to ducati asking for a solution. This is clearly a blot on the Ducati reputation and their Italian masters (Lamborghini) and ultimately Audi (owners) who can manage the occasional win at LeMans....lol. Frankly, this problem is overdue for Ducati to fix professionally....in the longer term interest of the Duc culture and tradition.

If enough customers complain to their dealers, the word will certainly get back to DNA and then the factory. I think it has, and they are working on it. Meanwhile, they are fixing bikes for those who are having problems. What more do you expect? And unfortunately, the vast majority of "aftermarket" solutions are not EPA or CARB legal for street vehicles. There will be mandatory smog inspections here soon enough.

After the last update nearly a year ago, my bike does not surge at any rpm. But I only use 'top tier' premium fuel, maybe that could be a factor.

One more thing that puzzles me... my bike's surging was only at small throttle openings and 3-4k rpm. I would think that there would be enough load on the engine at 75 mph (6k in 6th, more or less) to prevent this effect.

Bruder · Aug 20, 2014

Well what can I say IT'S DUCATI !!! Ducati was never ever perfect and it will be never ever pefect!!!!

You have to deal with each of the problems that's it! Or you have to buy a other bike.

For Exempel,
in italy Ducati have Summer Holiday for 3week, so Ducati is closed no body is there, they all on the beach!!

So if You need to order parts for your bike You have to wait until the
Holiday is over. Nothing is moving in Borgo Panigale. The good news is the Holiday is over this week. Thats Ducati I Love it

Totally agree with you Steffen.

I was driving home this evening on the freeway and it seamed like the engine was surging. I was holding a constant throtte position. The bike was in touring mode in 6th gear at about 6200 rpm. Has anyone noticed something similar?

My hyper is a 2013 model and does not likely have the latest ecu update. I'll take it in to the dealer this weekend.

Nate

YUP, mine does EXACTLY the same. I find the surging between 5500 and 6500rpm. I think Ducati is doing something funny with the fuel in that rev-range in order to pass the emmission laws in Europe.... :-(

An update to #27 (mine) of 2014,
I had the throttle recall done over the summer and that resolved most of the problem. I'm thinking that the rest - mostly when engine braking - may be improved by future software refinements or an aftermarket ECM add on. Also considering a dyno tune...
I would say I'm now 90% happy and adapting to this FBW technology.
I love my bike

peoples1234 · Oct 19, 2015

Mine surges at that RPM as well, I can tell it when I have the throttle lock set on the concrete slab.

I have all the updates and throttle recall done.

Biggest complaint about the bike is the fueling. Nevertheless 6200 in 6th gear is moving pretty good, so it isn't often I find myself in that position for long periods of time.

willmac · Oct 19, 2015

Mine has just starting surging too. It's a 2014 model.
5,500 kms on the clock now.
Bit disappointing as it's been good as gold up until last few hundred Km's.

zippy49 · Oct 21, 2015

I suspect that fuel quality may have something to do with this. There is always the chance of contamination. In the USA we have "Top Tier" fuel available, which has 5X the minimum required detergent additives. I never use anything else. If my Strada started acting up, I would try some injector cleaner before blaming the bike.

WiLZy · Oct 22, 2015

I haven't detected any surging by now, but I own the bike only for a few weeks (<1000 miles), besides my ECU mapping may fit for EURO 3 emissions.

Have you tried to bypass the exhaust valve?

Why would that have any effect on surging? It would be wide open at that RPM.

I agree - also chain tension seems to affect the overall smoothness and could be felt as surging.

The thing is, is that whatever is left in the hose from the last guy at the pump , is going in your tank. Since we're only putting in around 3 gallons, this could be a significant portion of the refill. So even if you're using the highest octane, a third +/-, could be low octane.

Ran into bad surging once and another refill tamed it.

I tried disconnecting and reconnecting the exhaust valve and experienced no changes aside from noise at low RPM.

Chain tension makes a big difference. It doesn't take much to really make it wonky.

Check out my review on the rapid bike evo. Doesn't cure it, because I believe it's a combination of things (light flywheel, e-throttle, chain tension, nature of the engine, etc), but it greatly helps and smooths out the entire power band.

I read the review earlier today - very detailed and much appreciated. I suspect the strada has different maps - I'm pretty happy with the way it goes about its business - but it's good to have the option.

I did test a BMW f800st and found the engine so linear that it was boring - does the evo preserve the character of the power delivery?
