Description

This device is a specialized, competition-only electronic component engineered for the high-performance Toyota GR MN Yaris. It is designed to modify the vehicle’s output speed signal. This achieves one of two distinct motorsport objectives, depending on the unit selected: either enabling accurate high-speed data for aftermarket telemetry or creating a deliberate speed display offset for specialized racing applications.

Product Overview & Track Application

In professional motorsport settings, the requirements for vehicle data can vary. For the GR MN Yaris, two specific Speed Jumper variants are offered. These cater to different competitive needs. Both ensure that vital speed information is correctly relayed to professional data acquisition systems, dash displays, and timing equipment used exclusively on the circuit.

Technical Function & Application-Specific Details

• Core Function: Both variants process the vehicle’s ECU speed signal. Their purpose is to correct or alter the data received by OBD-connected aftermarket devices, which is essential for accurate performance logging and analysis in a racing environment.

• Vehicle Application: Specifically developed for the Toyota GR MN Yaris (chassis GXPA16, G16E-GTS engine), for vehicles produced from January 2022 to February 2024.

• Variant-Specific Functions & Critical Notes:

  1. Part Number 15254 (For Deliberate Display Offset)

  • Primary Effect: Causes OBD-connected devices to display a vehicle speed that is different from the actual vehicle speed. This is a deliberate function for specific tuning or competition regulations.

  • Note: The factory vehicle speedometer remains capable of displaying speeds above 180 km/h.

  2. Part Number 15259 (For Overcoming OBD Limitation)

  • Primary Effect: Solves the common issue where standard OBD-linked equipment cannot display speed above 170 km/h. This unit corrects the signal, allowing supported devices to accurately read higher speeds.

  • Note: The factory vehicle speedometer remains capable of displaying speeds above 180 km/h.

• ⚠️ Critical Disclaimer – Strictly for Competition Use:

  • Both variants are unambiguously classified as competition-only parts. They are not legal or intended for use on public roads.

  • Their use is confined to sanctioned racing, track days, and dyno testing environments.
