Description

This device is a specialized, competition-only electronic module designed for the 2015-2020 Lexus GS F. It serves a singular, critical purpose in a motorsport environment. Specifically, it modifies the vehicle’s output speed signal to ensure absolute accuracy for aftermarket racing telemetry and instrumentation systems.

Product Overview & Motorsport Purpose

In high-performance track use, reliance on precise, real-time data is non-negotiable. This Speed Jumper acts as an interpreter for the Lexus GS F’s complex electronics. It delivers a clean, corrected speed signal specifically tailored for professional data loggers, dash displays, and other OBD-port-dependent racing equipment.

Technical Application & Critical Motorsport Disclaimer

• Core Function: Reprograms or alters the vehicle’s digital speed pulse output. This ensures that specialized racing electronics receive a reliable and representative speed data stream that standard OBD signals may not provide under extreme performance conditions.

• Vehicle Application: Engineered exclusively for the Lexus GS F (chassis code URL102, engine UR-GSE), produced from November 2015.

• ⚠️ Critical Disclaimer – Strictly for Track/Competition Use:

  • This is explicitly classified as a competition-only component. It is illegal and unsafe for use on public roads.

  • Installation will intentionally cause the vehicle’s factory dashboard speedometer and any street-legal OBD readers to display a speed that is divergent from the true vehicle speed. This is an accepted and necessary effect for circuit tuning and data accuracy.

  • Its sole purpose is to unlock accurate high-speed data transmission for the sophisticated sensors and displays used in professional time-attack, circuit racing, or dyno testing scenarios.
