Stupid stupid throttle

I've happily eliminated the free-play with the throttle spacer fix; and there's still a small dead-zone where revs don't move after throttle is turned - which I'm expecting/hoping will get fixed when I ask the service centre to reset the TPS at first service.

But, my throttle is really laggy! Here's an example: blip the throttle when completed stopped in neutral (or clutch pulled in, in 1st gear) at idle... Let's say you blip to about 3000rpm. Now try doing the same thing when the bike is moving at walking pace (clutch pulled in, 1st gear, blip throttle). For the same amount of throttle movement the bike doesn't rev nearly as much (maybe not at all in fact or perhaps up to 2000rpm) and sometimes there's a delay before the revs start increasing.

Occasionally the throttle does respond quickly when moving, and causes me to over-rev when changing gears at slow speeds.

This is liveable if I'm just pottering around town like a grandmother, but makes it impossible to ride in any quick fashion... E.g. Taking off from a set of lights requires turning the throttle then waiting to see if the revs move... If not turn throttle a bit more; ease clutch out, etc. I'm slower than cars now at taking off from a set of lights. I've never had a bike with an inconsistent annoying throttle like this; and anyone watching would think I'm a learner rider. I am used to instant throttle response that allows for fast launches, not diesel 4wd throttle response.

Anyone else experience this behaviour and can it be fixed ? Wondering if this is a side affect of the closed loop O2 monitoring or some feature of the Ecu to change throttle response depending on if moving or stationary or something else ?
 
Electronics

Welcome to all the electronics! I hate all the limitations. I looked real close at the 1299 but chose to buy a 1198 because it has way less electronic crap on it. I like all the power, not kill it with all the modes and traction control. My 1198 has a quickshifter which is on and traction control which is turned off. The electronic crap may make it easier and faster on the track but way less fun on the street. Wheelie control???? That's crap. I like packing the front wheel 3 foot high at 100 plus mph. Its almost like they build a fast bike and then put limitations so beginners won't get on the bike and kill themselves?
I also had a 2014 KTM superduke. I paid a bunch for all the stupid electronic crap. I then had to spend more on a offroad dongle to disable all the stuff that makes it slow.
 
Actually that gives me an idea... I'm going to turn off all the electronics (dwc, ebc, etc) and see if anything affects/improves the throttle response... Well I just tried in the garage and with all electronics turned off it still behaves the same. Ie ok throttle response at standstill and doughy laggy throttle when bike is moving at walking pace.

I've been thinking about this; I think it's a function of the throttle having a lot of travel. My idea throttles are less than a quarter turn.
 
My bike's throttle slack had been removed before delivery, I have full Termis with upmaps, a race mapped ECU, a PCV with autotune and I ride in race mode. My throttle is very smooth, but very quick, just the way I like it. :D

Never heard anything like this before. Check out the microswitch on the clutch lever. The reason for that switch is that it changes the map depending on whether you are in neutral or in gear with the clutch pulled in. Like in gear in first.

Probably saved yourself quite a bit of money too. Buying a 1198 instead of a 1299 I mean.
 
Same thing started happening to my 14R and that's why I sold the dam thing.

Happened probably 40% of the time towards the end. Felt really fluffy and dead and wasn't consistent towards the end of our relationship. First 6 months was perfect and I don't know what changed but there was definitely something wrong with it.

You'd blip the throttle repeatedly and would jump 1500>6000RPM as it should but then it would start to play up and you would feel a delay and it'd blip to 3000RPM for example instead of 6000RPM, just randomly bog down with a delay, feel like it was bogging down like an old two-stroke and then recover and start accurately revving back up to 6000RPM.

Found no information about it on the internet, my dealer had no idea what was wrong but they did acknowledge it happening. I couldn't be bothered with the hassle so launched it and ordered the new 15R.

So don't worry, you're not crazy but I'd drop it off at your local dealer and tell them to fix it or give you a bloody new one. What exhaust system/map you running?
 
I had something like that happening, but it was a plug that died on me. Once the plugs were replaced she was fine again.
 
Odie, could this is not a result of the spacer kit installed, or was it like this before you installed that kit also?
 
Bwah, hahahaha. :D Blipping at 3000rpm. Oh, that's good. That's hardly off idle on a race engine. It should blip just fine up around 6000rpm+ which is where you should be downshifting when riding hard. Yes the throttle is lethargic at low revs, but mine is flawless when I'm riding properly. When I'm riding like a grandma, I have noticed somthing similar to what you mention. But it always goes away when I ride for real.

Make sure your engine is in 195hi in sport mode.

Going to have to disagree with the assessment on the electronics being in place that prevent performance. Not to mention that you can turn them all off.

But yes, I have this issue when gently blipping from closed throttle.

yeah, i have the same issue blipping downshifts from any rpm range with everything turned off. the throttle just doesn't respond in real time to wrist input...
 
I find that the blipping is absolutely instant. Best of any duc I've had.

On issue I did find is don't QS down from 2nd to 1st...drops to N. Almost had a very bad time with that one.
 
Hmmm! I don't have a problem with it at all on my 13R in the sport mode (I think it's 195 lo). I have around 2K miles, mostly track. I'm betting you have a problem with the tps. The throttle is ride by wire so that's one electronic switch you can't turn off!

I have, and find it very useful. In normal use it always goes from 2 to 1. But if I just slightly tap it just right, it goes from 2 to N, and I don't have to use the clutch at all when coming to a stop at stoplights.

Bradp51, I thought you were joking and that I should check my quick shifter fluid as well :) but you are absolutely correct!

Which idiotic ducati engineer thought it sensible to change the throttle response depending on clutch position?

So this is what I found:
1. When stopped; or when moving and with clutch fully in, the throttle response is instant.

2. When moving and clutch out or only half-way pulled in (not enough to engage microswitch) then throttle response is terrible.

For me I normally use two fingers on clutch, so I'm pulling it in enough to disengage the actual clutch but sometimes not enough to engage the micro switch... Explains why sometimes throttle response is crappy and sometimes ok (if I've pulled in the clutch far enough).

This makes it a bit of lottery as to what kind of throttle response you get when doing a quick start from stopped... If you rev the engine before the micro switch disengages as you let you the clutch you will get good response... If you let the clutch out a little too much before revving it then you get crappy throttle response and might stall the bike.

Similarly if changing gears, it depends on when/how you pull the clutch in as you blip throttle as to what sort of response you get.

For now I've moved the micro switch lever to the other side of the pin so the bike thinks the clutch lever is always out.. At least then I'll get consistent throttle response. Means I have to start the bike in neutral and turn of dqs so the bike isn't always trying to blip even with clutch in.
Next I'll try taping the microswitch on... But again won't be able to use dqs.

If I have the bike tuned (eg rapidbike or tuneboy) then I would guess this behaviour can be fixed?
