FuelX Pro+ Dual O2 Sensor Duke 390 Gen 3 Install and speed test | FIRST On YouTube by Me

Installing the FuelX Dual O₂ Sensor Module on my KTM Duke 390 (Gen 3)!
This is a full plug-and-play installation — no wire cutting, no errors, and fully reversible.

In this video you’ll see:
✔ How to locate both O₂ sensors (upstream & downstream)
✔ How to disconnect the stock connectors
✔ How to connect the FuelX dual harness correctly
✔ LED indication and calibration
✔ Best place to mount the module
✔ Real ride feedback after installation


What FuelX Dual O₂ Sensor Improves:
• Smoother throttle response
• Reduced knocking/jerking at low RPM
• Better fueling with stock/BMC air filter
• Cleaner power delivery during aggressive riding
• More stable idle and improved low-end torque

This mod is perfect for Duke 390 Gen 3 riders who want a safer, smoother and more refined ride without affecting the bike’s warranty.
