UPGRADE YOUR LEXUS IS WITH FN TUNED

The Lexus IS blends luxury, rear-wheel drive attitude, and performance roots inspired by motorsports and sharp chassis tuning. It’s built to be smooth, confident, and fast when pushed. But the factory drive-by-wire throttle holds it back, especially off the line.

The solution is the FN Tuned throttle response controller. It cuts throttle lag instantly and gives you direct control over how your IS reacts to your pedal input. With four adjustable modes and 36 fine-tuning levels, you can set it up for aggressive backroad runs, spirited city driving, or calm daily cruising. Plug-and-play, Bluetooth-controlled, and fully untraceable, this is the throttle upgrade your Lexus IS has been missing.

FN Tuned Throttle Response Controller for Lexus IS

Install in 15 Minutes. No Tools Needed.

  • ✔

    Turn off your vehicle and keep the key fob at least 35 feet away. This prevents the key fob from triggering the ECU, ensuring a complete electrical shutdown.

  • ✔

    Locate the pedal position sensor (usually behind or at the top of the gas pedal assembly) and unplug the factory connector.

  • ✔

    Connect the male and female ends of the FN Tuned harness to the corresponding sockets. Ensure you hear a “click” each time.

  • ✔

    Secure the FN Tuned module somewhere in the footwell area with the included zip ties, make sure the module or the wiring does not block any moving parts.

  • ✔

    Activate your unit using the mobile app.
