Description

The HKS Power Editor Vehicle-Specific Kit is a straightforward, highly effective plug-and-play tuning solution designed to deliver a significant and immediate power increase for the GR Yaris Gen2. By simply intercepting the boost pressure sensor signal, this complete kit allows you to safely raise boost levels, resulting in sharper acceleration, stronger mid-range torque, and extended power in the high-RPM range. With pre-loaded HKS-tested data and a dedicated installation harness, it offers a remarkable balance of convenience and proven performance for both Manual and Automatic transmissions.

Product Overview & Purpose

This system provides an accessible entry into performance tuning by focusing on a key parameter: boost pressure. It works alongside the factory ECU by recalibrating the signal from the boost sensor, instructing the turbocharger to produce more boost safely within the engine’s tolerances. The kit includes everything needed for a clean, reversible installation, making it an ideal first performance modification.

Product Highlights

⚡ Proven, Out-of-the-Box Power Gains
Installed with the included HKS-tested preset map, the Power Editor delivers tangible results:

• Manual Transmission (MT): +17kW (23PS) and +27Nm (2.8kgf·m), achieving up to 217kW (295PS) and 438Nm.

• Automatic Transmission (AT): +11kW (15PS) and +19Nm (1.9kgf·m), achieving up to 194kW (264PS) and 389Nm.
  Gains are focused in the practical 3,000-5,000 RPM range for sharper daily driving response, with strong power holding to the redline.

🔌 True Plug-and-Play Installation
The kit includes a vehicle-specific harness that connects between the factory boost pressure sensor and its wiring via simple couplers—no wire cutting or splicing required. The compact main unit mounts neatly above the fuse box, adding a subtle performance accent to the engine bay while keeping installation clean and completely reversible.

🛡️ Safe, Conservative Tuning Philosophy
HKS’s preset data increases boost by a moderate ~10-15 kPa (0.10-0.15 kgf/cm²) over stock. This conservative approach prioritizes long-term reliability and safety with factory fuel and timing maps, making it a trustworthy upgrade for daily-driven vehicles.

💻 Optional Customization with Easy Writer
While powerful out of the box, the included USB cable allows connection to a PC running the free HKS Easy Writer software. This enables advanced users to review data logs or create custom boost maps for fine-tuning, though it is not required for operation.

Installation & Usage Notes

• 🔧 Straightforward DIY or Professional Installation
  The harness design allows for a relatively simple installation. However, ensuring connections are secure and the unit is properly mounted is crucial. Professional installation is always recommended for optimal results.

• ⚠️ System Requirements & Recommendations

  • Supporting Modifications: While it works on a stock car, for best results and safety, it is recommended to pair it with HKS intake and exhaust systems to improve airflow and cooling, as used in HKS’s testing.

  • Reset Function: The included reset connector allows instant reversion to the stock signal for dealership visits.

  • Not a Full ECU Tune: This system adjusts boost only. For comprehensive fuel and timing adjustments, the more advanced Power Editor R system is recommended.
