NOTE: DOES NOT WORK ON 2021+ EU MODELS

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 sensor from the exhaust header. You may add one below in options.

  1. Better power much less surging 5 Star Review

    Posted by on 26th Apr 2021

    This is a very good improvement overall. I agree with the other reviewers on the benefits of this. I thought the bike was pretty good stock but this has removed much of the lean surging that I was experiencing. I highly recommend this if something like a Power Commander is just too expensive. I am pleased so far. I does make it run better. My bike KTM 2020 690 SMCR

  2. Simple, Great MOD! 5 Star Review

    Posted by on 19th Apr 2021

    I have put a few hundred miles on the bike since installing the fuel dongle & deleting the O2 sensor. It really helped smooth out the bottom end and idle. It was crazy easy to install and delivered amazing results for the amount of effort required. I would definitely recommend throwing this on your 690/701!

  3. 2021 690 SMCR- Works flawlessly 5 Star Review

    Posted by on 29th Mar 2021

    Works as advertised, no CEL light and it woke the bike up dramatically. Don’t tell the cops, but where this thing used to fall on its face low end, it now absolutely loves to RIP wheelies of the off-road variety of course, because we are respectful law abiding citizens, right? ;).

    All jokes aside, took less than 5 minutes to install all together and really woke up the bike and I’m super happy with the purchase.

    My only complaint.... it didn’t come with a Rottweiler Performance sticker like my other parts did. I teared up a little. I love to sticker bomb my toolboxes and add some to the bike here and there.

  5. If you have a 2020 KTM 690 SMC R buy the fuel dongle. 5 Star Review

    Posted by on 18th Mar 2021

    This fuel dongle is the best upgrade to make your bike run better in the under 5500 rpm range especially for the price!

    This fuel dongle is the best upgrade to make your bike run better in the under 5500 rpm range especially for the price!

  7. MUST HAVE!!! 5 Star Review

    Posted by on 4th Mar 2021

    Installed on a 2012 690 enduro R.
    I couldn't stand that the bike could not be ridden under 4000rpm. The ridiculous fuelling caused so much chugging and power loss that i was ready to trade the bike.
    I installed the fuel dongle and drove away on a completely different bike! Yes there is more power for sure but the fact that there is absolutely no loss of smoothness in any of the rpm range is everything. It's mind boggling that the bike comes from the factory as it does and even more crazy that a 5 min fix for under 40 bucks cures everything. I've spent over a thousand on exhaust and filters on other bikes and didn't get a result anywhere close to this. It's actually stupid not to buy it. If you read this far and still arent sure, make a doctor's appointment, you need your head checked!

  8. Great Little Upgrade 5 Star Review

    Posted by on 18th Feb 2021

    I was amazed that such a small, inexpensive & easy to install upgrade could do that much to the low end performance. I couldn't be happier with the fueling dongle. I installed this on a 2021 690 Enduro R

  9. fuel dongle 5 Star Review

    Posted by on 28th Jan 2021

    Easy install. Works great! Much better low end

  10. Great Product 5 Star Review

    Posted by on 24th Jan 2021

    Great product, quick shipping to North Alabama.

    Suggestion - maybe add the option for a small pack of anti-seize for the O2 Plug threads.

  11. A different bike 5 Star Review

    Posted by on 18th Jan 2021

    Firstly my parcel arrived way quicker than expected. Less than a week from California to Australia.

    I have a Vitpilen 701, and it is quite a poor bike in low revs.

    I bought one for my bike and a mates. Both of us agree that this made it into a different bike. I am just about to put another order in for more parts (SAS/Canister removal).

  12. I feel the difference 5 Star Review

    Posted by on 27th Nov 2020

    2020 KTM 690 SMC-R: At Low speeds cruising the bike's throttle response was not smooth or responsive.
    Now with the fueling dongle the bike is now very responsive and very smooth at both all levels of the throttle. Most of all....the bike is not running HOT anymore around town and transitions from cruising to High Speeds are just the Blast I love.

  13. The best, least expensive and easiest to install upgrade you can make. 5 Star Review

    Posted by on 25th Nov 2020

    I’ve swapped my 2018 701 Enduro over to a Supermoto and just wasn’t happy with the gearing. Now with this easy to install “dongle” I’m getting the power curve I feel I was getting with the larger rear tire and sprocket setup on the enduro. For me I’m feeling the difference in the low to midrange area. This should be the first mod to any 701, all of the upgrades I’ve gotten from Rottweiler have been top notch....more to come.
    Stop putting more miles on your bike without this!

  14. WOW! 6 Stars 5 Star Review

    Posted by on 4th Nov 2020

    This is absolutely the first thing you should buy for your 690/701. I am absolutely blown away but this super simple product. After reading the reviews I was sure it would do something but not have such a profound difference in midrange power. Right where you expect the bike to bog down like it would stock, it just pulls itself back into that sweet sweet power band and flys. An absolutely must, especially if you live and ride in the mountains with steep inclined corners, this is what you need. This could be $70 dollars more and I would still think it’s an amazing value. Get this NOW!

  15. You want smooth ? 5 Star Review

    Posted by on 25th Oct 2020

    Bike stock low rpm is rather rough ,installed dingle and made noticeable difference in smoothness, DO IT !

  16. Amazing product. 5 Star Review

    Posted by on 19th Oct 2020

    The fueling dongle made itself known as soon as I started the bike as the idle was noticeable improved. The low speed throttle response was much smoother, the surging and bucking were replaced by clean fueling response which allows easier modulation. This is an excellent product at a low price. Thanks Rottweiler !!!

  17. Feel the difference 5 Star Review

    Posted by on 17th Oct 2020

    After installing dongle, the bike doesn’t sputter when revs are lower, and you crack on the throttle.
    Also installed a 16 tooth countershaft sprocket at the same time and the lugging you felt when going slow is gone.

  18. Must buy item 5 Star Review

    Posted by on 28th Sep 2020

    I used to had my check engine light on with O2 sensor problem. It may caused by the booster plug. It took me about 5 mins to install and the check engine light is gone! Very smooth acceleration and it’s a must buy item!

  19. Awsome mod 5 Star Review

    Posted by on 15th Sep 2020

    This fuel dongle is the best mod for the money
    It does exactly what it should, smooths the bike in low revs so you get much better control
    plus it takes 5 min to install

  20. Good product 5 Star Review

    Posted by on 1st Sep 2020

    The easiest mod I've installed. I do notice a difference in the low end response. My bike seems to have better throttle response off the bottom. For the price I would recommend this dongle if you can't afford the PC5.

  21. Great value 4 Star Review

    Posted by on 26th Aug 2020

    Installed the fuel dongle and removed the O2 exhaust sensor on my KTM 690 SMC/R. Installation was simple and took approximately 15 minutes. The low speed fueling does seem smoother and surprisingly my fuel mileage improved slightly on my first tank after installation. It's absolutely worth the $40 investment.

  22. 500 EXC-F 5 Star Review

    Posted by on 20th Aug 2020

    Fuel dongle works perfectly, no more lean surge, worked on my Superduke and now on my 500 EXC-F. Easy install.

  23. Great easy product 5 Star Review

    Posted by on 17th Aug 2020

    Fitted in 1 minute...honestly feel awesome. Way smoother...maybe I am dreaming but feels way more powerful.

  24. Specs tell all 5 Star Review

    Posted by on 4th Aug 2020

    Honestly, I don't know if I could tell you there is a major difference in anything other than it seems to have a smoother idle when cold. Either way the specs are on paper and for $30, that's good enough for me.

  25. Surely the best bang for buck mod 5 Star Review

    Posted by on 9th Jul 2020

    Works exactly as advertised, smooths out that low rpm jerkiness and the bike seems to run a little cooler. Very easy to fit, takes maybe 10 minutes. Recommended.

  26. Easy install with good results 4 Star Review

    Posted by on 26th Jun 2020

    Easy install with good results. Definitely an improvement but nothing drastic. For the price I recommend it.

  27. instantly improved the bike 5 Star Review

    Posted by on 22nd Jun 2020

    Very easy to install, and was an instant improvement. Just wish I did this sooner, I am at 10000km with the bike now.
    This should be the first mod you do.

  28. Makes an Improvement 4 Star Review

    Posted by on 20th Jun 2020

    My 2018 690 Duke was a bit rough at low RPM (lugging the engine). Most of this is due to the large single power pulses and small/light flywheel. Some of it is due to a lean fuel/air mixture (not enough fuel to burn properly) at low RPM while the engine is warm. This dongle smoothed some of the jerkiness out due to the lean condition. However, the jerkiness that is associated with the power pulses and light flywheel remain - as expected. This is a simple to install, inexpensive mod that will give you a little more power range down low. If you want to smooth the engine even further, find a heavier flywheel.

  29. IT REALLY WORKS!! 5 Star Review

    Posted by on 8th Jun 2020

    To be honest I want expecting much out of something that claims to work so well and be so cheep, but I was wrong. This took all of 5 minuets to install and then did the 15 minute idle reset just to be safe and then boom. It's a completely new bike runs so much smoother increased throttle response, i'm more then happy with this product and would highly recommend to anyone!

  30. Smooth as butter 5 Star Review

    Posted by on 25th May 2020

    Very easy install and solved a problem that has plagued we for a while. My bike stalls at the most inconvenient time like a water crossing so I got the dongle and so far it's all good.

  31. Best value product 5 Star Review

    Posted by on 28th Apr 2020

    Bike runs super smooth now, especially at low RPM, it no longer chugs like a tractor. Best value for the money.

  32. Definite Improvement 5 Star Review

    Posted by on 24th Apr 2020

    It helps smooth out the low RPM throttle, where the factory map is the worst. No it doesn't do everything a PCV does, but its a cheap effective alternate. Noticable improvement in my 701 E with this dongle and a Wings exhaust

  33. Best bang for the buck! 5 Star Review

    Posted by on 29th Feb 2020

    This thing is miraculous. Took all of 3 minutes to install and the results were instantaneous. Smooths our the low end at take off with no more stumbling or jerkiness. I was a little skeptical but after reading reviews all over the KTM forums I said what the heck. All I can say is that at less than 30 bucks this is the FIRST thing you should purchase. I am very happy with the Fuel Dongle and definitely recommend it to any KTM 690 owner.

  34. Works as promised 5 Star Review

    Posted by on 10th Jan 2020

    It took me 10 minutes to install. Works like a charm.

  35. First mod for your bike 5 Star Review

    Posted by on 26th Dec 2019

    I've put this in a 2019 Svartpilen 701 that I just got, and it works phenomenally. The bike in stock form is unusable in the 2-5k RPM range. This dongle helps a lot, making any RPM +3k actually useful.

    If you've just got this bike, this is the first thing you should do to it.

  36. I shouldn’t have waited! 5 Star Review

    Posted by on 28th Nov 2019

    With 13,000 miles on my ‘17 KTM 690 Enduro R the O2 sensor went bad. I finally decided to get the fuel dongle and plug and it made it so much smoother transitioning off idle. Now those slow sections of single track are much easier. Cheap, easy performance upgrade. DON’T WAIT!

  37. easy mod 5 Star Review

    Posted by on 14th Nov 2019

    Reasonably priced, easy to install, makes the bike run smoother, Definitely would recommend.

  38. Product that Works! 5 Star Review

    Posted by on 18th Oct 2019

    Wasn’t sure this dongle would do anything, as the price was really cheap. Boy was I wrong. My 2019 KTM 690 R displayed all the regular too lean problems associated with this model, jerky off the bottom, gurgling at very low speed in traffic. Figured what the hell, will give the Rottweiler Fuel Dongle a shot. Runs great now! No more popping on deceleration either. This thing works! Will require 5 minutes of your time to install. I highly recommend it

  39. must have 5 Star Review

    Posted by on 6th Oct 2019

    Took longer to get the cover off my bike then to actually install.
    Bike runs a lot better and way les jerky now. Great buy for the 701 Husky or 690 KTM

  40. Fuel Dongle works a Treat 5 Star Review

    Posted by on 4th Oct 2019

    After running up 1500kms on stock 2019 690 Enduro R I found the lower rev range to be a tad erratic
    Installed the Fueling Dongle along with the Canister Removal Kit and found a real difference to the smoothness = no more surge and a better balance
