Product Description
The Rottweiler Performance 'Fueling Dongles' are an effective and simple method to improving the fueling mixture of any fuel injected KTM by allowing the stock ECU to deliver a proper mixture at low to mid RPMs. By replacing the stock narrow band O2 plugs with these simple to install dongles, the Rottweiler Fueling Dongles feed the stock ECU a pre set signal that substantially smooths out the lower end power delivery reducing the jerky transition between the extremely lean low RPM mapping and the open loop upper end mapping. Overall average air fuel ratios also tend to richen up by about .5 to 1 point as well allowing the user an inexpensive option to 'bump up' the richness of their fuel delivery if the cost of a Powercommander is not currently an option for them.
How do they work? It's actually quite simple. The stock ECU is set to lean out the fuel delivery to a very lean 14.7 air fuel ratio (AFR) under 5500 RPM and 20% throttle. Once the engine has reached a sufficient warm up the ECU 'listens' to the stock narrow band O2 sensors and looks for a particular signal to keep the bike in that lean condition. This causes heat issues from extremely hot header pipes, makes the motorcycle jerky at low RPMs and reduces power. The Rottweiler Fueling Dongles send a return signal to the stock ECU that keeps the low end fueling at a much better running 13.8 +/-. A mixture that translates into an overall better running motorcycle.
Note: When running our Rottweiler Fueling Dongles, you have the option to remove your stock O2 sensors from the exhaust header F+R. Click below for O2 bung plug options.
- 2014+ SD and ADV use 12mm threaded O2 plugs
- All 2013 and older 990 LC8 and 1190 RC8 models use 18mm threaded O2 plugs
Notes, Suggestions or Precautions:
Rottweiler Fueling Dongles work very much the same as the 'O2 Eliminators' that typically come with Powercommander piggy back ECUs. You do not need these dongles if you are also purchasing a Powercommander. Tests have shown that average AFRs (air fuel ratios) richen up almost a full point when using the Rottweiler Fueling Dongles. They come in pairs. One for each cylinder and plug into the electrical harness replacing the stock O2s.

Works like a charm.
Posted by Rick Hobbart on 13th Jun 2017
Completely fixed my jerky throttle. Cheap and easy stepping stone to a Powercommander if it's not yet in your budget.

Dramatic change in bottom end
Posted by Kevin M on 4th Jun 2017
Should be like this from the factory, 3k-4.5k rpms are now usable, smoother take offs, able to use lower rpms so downshifting is reduced, smoothness is greatly increased. Feels like a new bike

Fixed the lean pop.
Posted by Tim on 16th Apr 2017
Did the SAS and Canister removal. Since a had installed a muffler off a Super duke muffler on my 1190 I had a lean pop on decel. Decided to install the fuel dongals at the same time. Problem solved.

Works just as advertised.
Posted by aarontt28@gmail.com on 17th Feb 2017
I replaced the cat with an arrow mid pipe and the end can with a Mivv carbon. The fuel dongles smoothed out the idle and throttle response. I would recommend these.

Low speed fueling dongles for KTM1190 adventure.
Posted by Colin. on 21st Jan 2017
I live in Australia & shipping was as specified time wise ( good ). Dongles did as specified also, smoothened out the bottom end, up to aprox 4.5K, could not notice any torque increase but power is more linear, smoother & less snatchy down low. Overall bike is aprox 20% or more faster up to 4.5K even though I could not notice more power, assume the more linear nature of torque now is masking the increase in power delivery.

great!!!

Cleans up the looks of the bike :)

best cheapest mod you could do
Posted by lpmoto on 23rd Dec 2016
Picks up low throttle leanness , for super smooth throttle on the bottom ,

easy install

Works as advertised, bike runs better at lower RPM's,simple installation.

Easy install, quality components
Posted by Dave on 26th Oct 2016
Bought these dongles, along with the mild steel plugs, after installing the intake system and SAS removal S3. It was a very quick install on the plugs and the front cylinder exhaust. The rear cylinder exhaust was a little more tricky, no fault of Rottweiler. Removing the right gas tank, along with an allen socket, swivel socket, and a 10" extension made putting in the plug much easier.

Easy to Install and Worked
Posted by John L on 24th Oct 2016
I installed the Fueling Dongles on my Bone Stock 1290. Low Rpm throttle response is allot smoother. Installation was easy..
-
They work!!!
Posted by Jim on 7th Oct 2016
My first impression after installing the fueling dongles is
that they work as advertised. Low speed throttle response is much better. Slow speeds on the trails are more enjoyable. Thanks for a great product. -
Works as advertised

Eliminated the hunting of the engine on my KTM 1290 SA at low speeds as advertised.

Simple but effective inprovement
Posted by Peter From Australia on 9th Sep 2016
Fitted Wings exhaust to my Superduke, Then fitted fueling dongles. Very impressive, smooths out the bottom end, much stronger from idle as you let the clutch out, much harder to stall. More tractable round town. Nice simple rideability improvement. Thanks Rottweiler:)

Transformed my ride
Posted by Curt on 19th Aug 2016
These simple little dongles completely changed the way my 1290 SA handles at low rpm and in the lower gears. Precise throttle control is a breeze - no more lunging! The also reduce the dreaded hot seat this bike is infamous for. They didn't eliminate the toasted buns but they helped. They did eliminate the throttle control issue and I couldn't be happier with the purchase. Makes me wonder what the powercommander would do - saving up for it next!

Just what the 990 needed
Posted by BC on 6th Jul 2016
I finally grew tired of my SMT's snatchy throttle (stock air box and slip on exhaust) and decided to try these out since I have zero interest in fiddling around with tuning. They worked out perfect which makes it a no brainer considering the cost and simplicity of installation. Much better throttle response around town, in roundabouts and I'm no longer hesitant riding in the rain. While researching these I remember reading somebody's concern about losing mpg due to the richer mixture but honestly I'm experiencing the opposite since I can comfortably cruise one gear higher now.

Night and day difference
Posted by Robert Bown on 4th Jul 2016
Thanks Rotty staff for probably the single best, cheapest mod I've installed on a bike aside from maybe a Fender Eliminator because I'm incredibly vain.
Night and day difference, bike runs way smoother and feels better around town, noticed the difference as soon as I turned out of my driveway. Simple install and bike looks fractionally cleaner, too. Thanks again! -
Exacty as advertised
Posted by Brad on 20th Jun 2016
Just installed the Dongles on my 07 990 Adventure and they work exactly as advertised. Totally smoothed out the power delivery at part throttle and below 4k, also eliminated the part throttle hiccup at 4.5k that the bike previously had. Gas mileage suffered a bit, as expected, but a great value for the price.

excellent mod
Posted by rick seawright on 20th Jun 2016
Install is easy. They function as designed Thanks Rottweiler for a product that works

fuel dongles
Posted by todd on 17th Jun 2016
Great quality nice and tight clip in components. Have smoothed out throttle response. Would recommend to those who are not looking to fit a power commander v any time soon. A+++

awsome
Posted by seb on 17th Jun 2016
Worked great! I feel like it pulls a wheelie even easier. Awesome product and removed weight from the bike too.

Smooth
Posted by Dave on 7th Jun 2016
Simple but effective. First ride after install and instantly noticed much better throttle under 4k rpm.
-
great
Posted by Matt on 6th May 2016
Made all the difference. Runs completely smooth at low rpm.
Yeeha -
Must haves
Posted by Unknown on 26th Feb 2016
I just installed on my SDR. Night and day positive diff.
Sweetens the ride tremendously, much smoother.
These are a no-brainer for the SDR. -
they work great!
Posted by Unknown on 22nd Nov 2015
I thought the fueling was pretty good on the Super Duke but a little fluffy and some vibration/coarseness at 4k rpm and below. These dongles eliminated all of that and the bike feels much better; throttle response is smooth and the vibration is reduced enough that I can use a gear higher than before when cruising. A revelation. My bike is stock except for a Yoshimura slip on.

excellent

Excellent Solution
Posted by Kevin on 9th Oct 2015
It's a band-aid but a simple, cheap and very effective band-aid for the snatchy/surging/stumbling during low RPM light throttle. Bike is much smoother and more enjoyable but does run rich in the aforementioned conditions so there is the occasional backfire. An acceptable trade-off for the benefits especially considering the cost. A full PCV with associated intake/exhaust mods and custom dyno tuning is the better alternative for roughly 20x the price. I'm very happy with the dongles.

No more snatchy 990 ADV throttle!
Posted by KTM Mike on 4th Sep 2015
These dongles do exactly what they said they would - essentially eliminated all of the snatchyness - made the bike much easier to ride in most all conditions.
-
excellent and inexpemsive addition
Posted by Unknown on 23rd Aug 2015
Awesome product! Removes low end stumble and allows to warm up faster.

smooth your fuelling with dongles
Posted by Unknown on 10th Aug 2015
Dongles did what I was hoping. I no longer have that irritating surging the engine made on 990 adventure. Before I was using clutch to smooth it out and I stalled the engine several times before in technical riding situations. I really like my bike now. My confidence has been raised. Buy it!!

Cured a snatchy, hair trigger, throttle
Posted by Ralph on 8th Jul 2015
Great fix for a snatchy throttle on a 2011 KTM 990 Adv. Rottweiler seems to have got the resistance right pushing the ECU into a far more palatable, richer, fueling map which has made an almost revelatory difference to the bikes 'rideablity'.

6th gear under 75mph? YES
Posted by Matt Myers on 5th Apr 2015
Quick fix for the 1290 SD-R Smooth/predictable transition from cruise to WOT. $ well spent.
