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 Power Commander 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 Power Commander piggy back ECUs. You do not need these dongles if you are also purchasing a Power Commander. 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.
