O2 Sensor Emulator Harley-Davidson Models (2021+)

Fix sensor errors, improve throttle response, and restore performance after exhaust upgrades.

This updated O₂-sensor emulator is specifically designed to cure the ECU fault codes that appear on 2021-on Harley-Davidson models with three oxygen sensors after fitting aftermarket exhausts.

✅ Key Features

• Eliminates error codes triggered by exhaust mods on 2021+ Harleys (including 3-sensor bikes).
• Plug-and-play installation – connects in minutes, no cutting or splicing.
• Continuous signal output keeps ECU happy and throttle response sharp.
