3rd O2 Sensor Decat Dongle - 890/901 Adventure (2024+)

Decat your exhaust setup without triggering error codes. This dongle is specifically designed for the 2024 and newer KTM 890 Adventure and Husqvarna Norden 901 models. It allows you to install a decat while preventing the check engine caused by the third O2 sensor located on the catalytic converter, allowing you to keep cruise control.

This plug-and-play emulator connects directly to the factory O2 sensor harness, simulating normal sensor behavior and keeping your ECU happy—no check engine light, no limp mode.
