Description

This product is a specialized, competition-use electronic accessory designed to modify the vehicle speed signal for the Toyota GR Yaris (2020/09-2024/03). It addresses known limitations in aftermarket OBD-linked equipment, allowing for accurate high-speed data representation on dedicated racing instrumentation.

Product Overview & Purpose

This device intervenes in the vehicle’s speed signal output. Its primary function is to ensure that aftermarket gauges, data loggers, or displays connected via the OBD port receive a corrected and usable speed signal at velocities where standard signals may become limited or inaccurate, specifically for competitive motorsport environments.

Technical Application & Critical Notes

• Core Function: Modifies the vehicle speed pulse signal to provide an accurate representation of speed to aftermarket electronic devices that rely on the OBD-II port for data.

• Vehicle Application: Specifically engineered for the Toyota GR Yaris (GXPA16 / G16E-GTS), model years from September 2020.

• ⚠️ Critical Disclaimer – For Competition Use Only:

  • This product is explicitly classified as a competition-only part. It is not intended for use on public roads.

  • Its use will cause the vehicle’s speedometer or any OBD-reliant display to show a speed different from the actual vehicle speed. This is by design for competitive tuning.

  • Key Specification: The factory vehicle meter is capable of displaying speeds above 180 km/h. However, standard OBD-derived data is often limited (e.g., capped at 170 km/h). This unit corrects that limitation for auxiliary racing equipment, while the factory cluster’s own reading may be affected.

Product Variants & Fitment

• Part Number: 15254 – Competition Use. For OBD devices where speed display differs from actual speed. Factory meter can display over 180 km/h.

• Part Number: 15259 – Competition Use. Compatible with both MT and AT models. For OBD devices that cannot display speed above 170 km/h. Factory meter can display over 180 km/h.
