UPGRADE YOUR LEXUS GX WITH FN TUNED

The Lexus GX is luxury wrapped around a real body-on-frame SUV. Proven off-road hardware, serious traction systems, and the kind of build that’s just as happy crawling rocks as it is cruising the highway. But modern Lexus tuning leans soft. The drive-by-wire throttle filters your inputs and dulls the response.

FN Tuned throttle response controller fixes that. It plugs straight into the accelerator pedal and recalibrates the factory throttle signal using vehicle-specific mapping. The result is immediate response and a more direct feel every time you step on it. With 36 adjustable settings, you can tune it for daily comfort, trail precision, towing confidence, or aggressive driving when the pavement opens up.

FN Tuned Throttle Response Controller for Lexus GX

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.
