Description

The HKS Power Editor R Vehicle-Specific Kit is a comprehensive, professional-grade tuning solution designed to unlock significant power and torque from the GR Yaris Gen2’s turbocharged G16E-GTS engine. This complete plug-and-play system combines a vehicle-specific wiring harness with the versatile Power Editor R unit, providing preset boost-up maps and advanced multi-dimensional control. It delivers substantial gains—up to +21PS and +2.5kgf·m of torque—through precise management of boost, fueling, and throttle response, all while maintaining OEM-like drivability.

Product Overview & Purpose

This kit bridges the gap between basic plug-in tuners and complex stand-alone ECUs. It works alongside the factory ECU, intelligently intercepting and optimizing key sensor signals to safely increase boost pressure and engine performance. The included, model-specific harness and pre-loaded data provide a powerful, “install and drive” upgrade path, while the free Easy Writer software opens the door to ultimate customization for experienced tuners.

Product Highlights

⚡ Significant, Proven Power Gains
Internal dyno testing confirms transformative results:

• Manual Transmission (MT): +16kW (21PS) and +24N·m (2.5kgf·m), achieving 218kW (296PS) and 439N·m.

• Automatic Transmission (AT): +15kW (20PS) and +37N·m (3.8kgf·m), achieving 208kW (283PS) and 433N·m.
  These gains are especially pronounced in the mid-to-high RPM range, dramatically improving overtaking, corner exit acceleration, and overall responsiveness.

🔌 True Plug-and-Play Harness Integration
The kit includes a GR Yaris Gen2-specific intercept harness that connects to the factory engine sensor wiring via dedicated couplers—no cutting or splicing required. This ensures a clean, reliable, and completely reversible installation that preserves the OEM harness integrity.

🎛️ Advanced Multi-Dimensional Tuning Control
Unlike simple boost controllers, the Power Editor R utilizes multiple sensor inputs for intelligent, conditional control. By accessing throttle position, RPM, and vehicle speed signals, it can apply different tuning maps for each gear and throttle opening. This results in smoother, more drivable power delivery that feels natural and factory-engineered.

💻 Pre-Loaded Maps & Unlimited Customization
The unit comes with optimized, preset boost-up data developed by HKS, providing impressive out-of-the-box performance. For ultimate personalization, the free HKS Easy Writer software allows users or professional tuners to create custom calibrations, fine-tuning for specific modifications, fuel quality, or driving style.

Installation & Tuning Notes

• 🔧 Professional Installation & Setup Recommended
  While the harness is plug-and-play, installation requires routing and securing the unit. Professional installation is recommended to ensure all connections are secure. Critical: The system should be installed and the vehicle tested/verified by a technician familiar with performance tuning.

• ⚠️ System Requirements & Best Practices

  • Supporting Modifications: For maximum and safest results, this tuner is best paired with HKS intake and exhaust systems (as used in testing) to ensure optimal airflow and cooling.

  • Reset Function: The included reset connector allows the vehicle to be returned to stock sensor signals instantly for dealer visits.

  • Custom Tuning: For aggressive builds or race fuel, custom tuning via Easy Writer is highly recommended to ensure optimal safety and performance.
