RALLY-MOTOR fuel dongle EU 2021+ KTM 690 - Husky 701
The new 2021+ EU-spec KTM 690 and Husky 701 are Euro-5 engines. They can't be fooled as easily as the older engines. Because of this the Rottweiler fuel dongle will cause an engine fail light on the dashboard after about 15 minutes of riding. The O2-sensor stayes in place with these new fuel dongle, because they pass just enough information to the ECU to prevent the warning light to come active. But...the AF-ratio is still richer, so the engine is running more smooth than without.
