Description

This product is a specialized, track-focused electronic device engineered for the 2022+ Lexus IS 500. It is designed to modify the vehicle’s speed signal output. Specifically, it enables accurate high-speed data logging and display on aftermarket racing equipment. This is crucial where both factory and standard OBD limitations exist.

Product Overview & Motorsport Application

For precision driving on closed courses, accurate telemetry is paramount. This device addresses a dual constraint in the IS 500. It overcomes the vehicle’s own electronic speed display limit. Simultaneously, it ensures a correct and usable signal is sent to professional OBD-linked racing instruments. This provides the true data necessary for performance analysis and tuning.

Technical Function & Critical Usage Notes

• Core Function: Intercepts and reprocesses the vehicle’s digital speed signal. It provides a corrected output that allows compatible aftermarket OBD devices to accurately read and display the vehicle’s true speed beyond factory-imposed limitations.

• Vehicle Application: Developed specifically for the Lexus IS 500 (chassis code USE30, engine UR-GSE), manufactured from August 2022.

• ⚠️ Critical Disclaimer – For Competition Use Only:

  • This is a competition-only part. It is not certified or intended for use on public highways.

  • Key Technical Note: The factory vehicle speedometer (dashboard meter) is electronically limited and cannot display speeds above 180 km/h. This device does not alter this factory meter behavior. Its function is to allow aftermarket OBD-connected products (like racing dashboards or data loggers) to correctly display and record speeds exceeding 180 km/h. This creates a dual-state where the race equipment shows true speed, while the factory display does not.
