Rottweiler Fueling Dongles (Pair)

$39.95

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.

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.

  1. fueling dongles 5 Star Review

    Posted by on 28th Oct 2017

    First off these people are great to work with and it's evident that they love what they do. Got the fueling dongles to richen my fuel ratio after I installed a mid pipe. Do your research and you'll find that everything these guys do is spot on. Looking forward to outfitting my Super duke with their intake system, sas removal kit and power commander unit as I can afford to do it.

  2. best mod so for 5 Star Review

    Posted by on 27th Oct 2017

    this is a no brainer for your 1290 SA. richens up very lean fueling at low throttle settings. I was surprised at the difference it made. strongly recommend.

  3. surprising performance improvement 5 Star Review

    Posted by on 7th Sep 2017

    Just bought this 990 Baja with low miles. Did not like being below 3500rpm as it was rough and running hot around town. Did an oil change (does it have to be that complex?) k&n air filter and a foam pre filter. With the dongles fitted it now runs cooler and smoother. Can trickle through town now at 2500-3000rpm. Rear o2 sensor still in the pipe but disconnected. Trying to figure out a simple way to remove it!

  4. Richening the low throttle openings provides smoother response 5 Star Review

    Posted by on 24th Aug 2017

    The dongles work as advertised. The stock map is pretty lean and snatchy when the throttle is just cracked open. Not what you want when first opening the throttle back up in the middle of a corner! Fattening up this part of the map smooths it out.

  5. Awesome !!! 5 Star Review

    Posted by on 10th Aug 2017

    Best 40 dollars I have spent in a while don't hesitate to buy these , they smooth everything out are easy to install , you will feel a difference imidiately, thank you rottweiler for a great affordable product that comes through with flying colors

  6. Worth every penny! 5 Star Review

    Posted by on 3rd Aug 2017

    Throttle response is improved but mostly the hunting, surging and abrupt low rpm crap is gone! Super simple to instal. Best upgrade per dollar you will find...

  7. superduke r 5 Star Review

    Posted by on 22nd Jul 2017

    If your not getting a PCV get these ASAP! Smooths out everything down low. Very noticeable difference when riding with a passenger, the bike just pulls from as low as 2800 rpm. No more jerk and shudder.

  8. More Magic 5 Star Review

    Posted by on 16th Jul 2017

    Everything Ive purchased and installed from Rottweiler has worked great! These dongles did everything as described, definitely smoothed out the low end power! Looking forward to buying more Magic!
    Thanks again,

  9. the best money ever spent on the Superduke 5 Star Review

    Posted by on 7th Jul 2017

    These dongles really cleaned up the fueling at low rpm just as advertised. Took about 5 minutes to install.
    If you have a stock Superduke you might not know it yet but you need those. Highly recommended.

  10. Awesome product 5 Star Review

    Posted by on 30th Jun 2017

    Very easy to install.
    Took the twitchy throttle response and smoothed it out. A lot nicer to ride below 4000 rpm
    Highly recommended

  11. Easy Easy Easy 4 Star Review

    Posted by on 29th Jun 2017

    These could not be any easier to install.
    Just unscrew the o2 sensor and follow the wires to the first junction, unplug the sensor and clip in the fueling dongles.
    Eliminated surging at steady throttle and also when driving in city traffic.

  12. Fixed my problem 5 Star Review

    Posted by on 28th Jun 2017

    Plugged them in and the check engine light went off. Made low end throttle control much smother.

  13. Works like a charm. 5 Star Review

    Posted by 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.

  14. Dramatic change in bottom end 5 Star Review

    Posted by 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

  15. Fixed the lean pop. 5 Star Review

    Posted by 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.

  16. Works just as advertised. 5 Star Review

    Posted by 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.

  17. Low speed fueling dongles for KTM1190 adventure. 4 Star Review

    Posted by 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.

  18. great!!! 5 Star Review

    Posted by on 13th Jan 2017

    Cleans up the looks of the bike :)

  19. best cheapest mod you could do 5 Star Review

    Posted by on 23rd Dec 2016

    Picks up low throttle leanness , for super smooth throttle on the bottom ,

  20. easy install 5 Star Review

    Posted by on 27th Oct 2016

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

  21. Easy install, quality components 5 Star Review

    Posted by 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.

  22. Easy to Install and Worked 5 Star Review

    Posted by on 24th Oct 2016

    I installed the Fueling Dongles on my Bone Stock 1290. Low Rpm throttle response is allot smoother. Installation was easy..

  23. They work!!! 5 Star Review

    Posted by 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.

  24. Works as advertised 4 Star Review

    Posted by on 29th Sep 2016

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

  25. Simple but effective inprovement 4 Star Review

    Posted by 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:)

  26. Transformed my ride 5 Star Review

    Posted by 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!

  27. Just what the 990 needed 5 Star Review

    Posted by 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.

  28. Night and day difference 5 Star Review

    Posted by 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!

  29. Exacty as advertised 5 Star Review

    Posted by 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.

  30. excellent mod 5 Star Review

    Posted by on 20th Jun 2016

    Install is easy. They function as designed Thanks Rottweiler for a product that works

  31. fuel dongles 5 Star Review

    Posted by 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+++

  32. awsome 5 Star Review

    Posted by on 17th Jun 2016

    Worked great! I feel like it pulls a wheelie even easier. Awesome product and removed weight from the bike too.

  33. Smooth 5 Star Review

    Posted by on 7th Jun 2016

    Simple but effective. First ride after install and instantly noticed much better throttle under 4k rpm.

  34. great 5 Star Review

    Posted by on 6th May 2016

    Made all the difference. Runs completely smooth at low rpm.

    Yeeha

  35. Must haves 5 Star Review

    Posted by 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.

  36. they work great! 5 Star Review

    Posted by 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.

  37. excellent 5 Star Review

    Posted by on 27th Oct 2015

    Works exactly as advertised, simple to install.

  38. Excellent Solution 5 Star Review

    Posted by 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.

  39. No more snatchy 990 ADV throttle! 5 Star Review

    Posted by 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.

  40. excellent and inexpemsive addition 5 Star Review

    Posted by on 23rd Aug 2015

    Awesome product! Removes low end stumble and allows to warm up faster.
