Rottweiler Performance Fueling Dongle - KTM 690 / Husky 701

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.

    Big improvement

    It took me all of 5 minutes to install on my duke. I took a ride and immediately noticed the difference. Much smoother throttle in the lower rpms. If you're looking to make a difference without forking out the cost of the power commander, then I highly recommend this dongle.

    This really works!!

    This is a easy fix,takes a lot of the hesitation/jerking at low rpm out of the Husky 701 !

    Good product

    The product was great and worked as expected. I really like the KTM Twins site, but you guys really need to work on getting the parts out quicker. Took three days before it even shipped. Too long in my opinion.

    Does what what is says!

    Not too difficult to install. On the KTM 690 duke you need to do the following for access to install: - Remove rear seat - Remove front seat - Remove right fuel tank cover - Remove right lower cover The just follow the wires from the O2 sensors to find the connector, there is only one it will fit, so its easy to find. I left the O2 sensor in the header and just zip tied the wires out of the way. This way I can re-connect it for "on road use". Will probably take about 15-30 mins. start to finish.
