Rottweiler Fueling Dongles (Pair)

$39.95

Product Description

race-series-armalite-small-2.png

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. Dongles Rule... 4 Star Review

    Posted by on 15th Oct 2018

    So was I just itching for a minor upgrade or just wanting another quality Rottweiler performance product?or, was I looking to rid my motorcycle of those unsightly O2 sensors? What I got was a cost effective, plug and play bit of smoothness added to my Superduke. My seat of the pants experience tells me I now have a smoother, more tractable lower RPM machine. My fuel economy computer makes it a fact I lost almost 1MPG with my spirited street riding style and lastly my smiling face let’s me know that coupled with the ABS/TC dongle I now have one hell of an ‘any gear, any RPM’ wheelie monster. Recommend? Yes! Why? Delivers on its advertised purpose.

  2. Money well spent. 5 Star Review

    Posted by on 28th Jul 2018

    These dongels work! As the description out lined 100% .
    Big change for small price.
    I didn't have a problem with how my SD9990R was but now its so smooth it makes riding the tighter slower sections much easier.
    THANKS ROTTWEILER.

  3. High quality, easy installation 5 Star Review

    Posted by on 26th Jul 2018

    High quality, just click these in and enjoy your big twin! Absolutely 5 stars.

  4. worth every penny 5 Star Review

    Posted by on 11th Jul 2018

    JUST GET IN ....PERIOD.now filtering with much more confidence and the pull from 6th gear leaves a big smile on my face...

  5. BUY THIS 5 Star Review

    Posted by on 7th Jul 2018

    These dongles transform the lower rpm range into smooth useable power. No bucking or jerking in slow traffic or parking lots. They make 6th gear under 80mph as it should be.
    Can my Super Duke get any better?

  6. Smooth 5 Star Review

    Posted by on 24th Jun 2018

    2017 KTM 1290 r. Much smoother at lower rpm. Most notably when idling through slow traffic. No longer feels like its going to rattle my teeth loose in 6th gear. No change in gas mileage after 2000 miles

  7. 990 SMT 5 Star Review

    Posted by on 17th Jun 2018

    2010 990 SMT, decat, Arrow pipes,block off plates, tune ecu. Great bike but low end fueling was still not right.

    Dongles fixed that, much better to ride slowly and in traffic. Great fix for the money. Easy install if you take the tank off. No downside that I can determine, mileage seems about the same.

  8. A different bike ! 5 Star Review

    Posted by on 16th Jun 2018

    As most/if not all say, these little fellas work great. The idle is smother, more consistent and the motor also runs cooler in the sub 5000 rpm range. Well worth the $40 price tag.

  9. Good solution to throttle response for 1290 super adventure T 5 Star Review

    Posted by on 23rd May 2018

    Fast shipping, good product it does what is advertised whit out any effect on the hi rpm range. Good job!
    But, you have to take of the gas tank for one dongle.
    Thanks!

  10. 990 adv fuel dongle 5 Star Review

    Posted by on 21st May 2018

    Why didn't I buy these sooner? My bike runs way better at low rpm's! I can actually use 6th gear without the motor feeling like it's struggling.

  11. Inexpensive and effective 5 Star Review

    Posted by on 11th May 2018

    WOW! The difference from this inexpensive and quick mod is very noticable. Heat is down and the lower RPMs are very smooth; power is more linear.

  12. By far the best mod! 5 Star Review

    Posted by on 4th May 2018

    2007 KTM superduke.
    I was about to sell this bike, I couldn’t get over the snatchy throttle. These fuel dongles made such a great difference in low throttle/low rpm it’s almost a different bike! This is the way it should come from the factory.

  13. Wow! Those work really well. 5 Star Review

    Posted by on 5th Apr 2018

    So smooth and clean power. I was having a stumble/gasp taking off from stops on my 1190R. That problem is gone and power is instant now.

  14. Smoothed out the low end very well. 5 Star Review

    Posted by on 4th Apr 2018

    An excellent product. Plug and Play. Really smoothed out the low rpm riding. Great for street riding, which is what I do mostly.

  15. Best mod second to a Powercommander 5 Star Review

    Posted by on 2nd Apr 2018

    This is a great stepping stone to a Powercommander V if it's not in your budget just yet (but should be!)

  16. AWESOME! 5 Star Review

    Posted by on 9th Mar 2018

    Hooked these up before my first time drag racing on a GT1290 and pulled a 10.6! super smooth off the line!

  17. Awesome 5 Star Review

    Posted by on 5th Mar 2018

    Made the bike power more linear, improved throttle
    Easy to install (the front O2 could be a bit tricky to find if you don’t want to remove the gas tank)
    Great addition with a great price.
    Combined it with an Arrow Maxi Race = nice sound :)

  18. can't believe I didn't install earlier 5 Star Review

    Posted by on 2nd Mar 2018

    Bike is so much better after the installation. Smooth as f.

  19. 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.

  20. 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.

  21. 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!

  22. 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.

  23. 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

  24. 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...

  25. 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.

  26. 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,

  27. 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.

  28. 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

  29. 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.

  30. 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.

  31. 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.

  32. 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

  33. 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.

  34. 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.

  35. 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.

  36. great!!! 5 Star Review

    Posted by on 13th Jan 2017

    Cleans up the looks of the bike :)

  37. 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 ,

  38. easy install 5 Star Review

    Posted by on 27th Oct 2016

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

  39. 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.

  40. 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..
