FuelDongle Euro 5+ Error Eliminator KTM 790 / 890 / 990 & Husqvarna 901 Norden 2024-2026 - FuelDongle

The FuelDongle Euro 5+ error eliminator stops the emissions (anti-pollution) fault when you fit a catalytic converter eliminator on a Euro 5+ KTM 790, 890 or 990, or Husqvarna 901 Norden. It plugs in between the connectors of the third lambda (O2) sensor on the catalytic converter and corrects that sensor's signal, so the engine fault never appears.

FEATURES

• Corrects the catalyst O2 sensor signal, so no engine fault
• Plug & play with sealed OEM connectors
• Does not increase fuel consumption
• Required when removing the catalytic converter

INSTALLATION

Follow the O2 sensor cable from the catalytic converter. Remove the seat, battery and battery holder to reach the sensor connector, fit the dongle between the two connectors, clear any stored fault codes and you are done.

All FuelDongle products are designed for competition and closed-circuit use.
