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.

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.

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

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

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

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 :)

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

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.
Posted by Nickle 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.

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!
Posted by Mark 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.

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

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...
Posted by frank 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.
Posted by Dixon Boggs 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!

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.
Posted by Daryl 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
Posted by Unknown 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.
Posted by Unknown on 28th Jun 2017
Plugged them in and the check engine light went off. Made low end throttle control much smother.
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.
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
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.

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.
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.

Cleans up the looks of the bike :)

Picks up low throttle leanness , for super smooth throttle on the bottom ,
Posted by firstname.lastname@example.org on 27th Oct 2016
Works as advertised, bike runs better at lower RPM's,simple installation.
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.

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

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

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.
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!
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.
Posted by rick seawright on 20th Jun 2016
Install is easy. They function as designed Thanks Rottweiler for a product that works
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+++
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.
Posted by Dave on 7th Jun 2016
Simple but effective. First ride after install and instantly noticed much better throttle under 4k rpm.
Posted by Matt on 6th May 2016
Made all the difference. Runs completely smooth at low rpm.
