The HKS Power Editor is a vehicle-specific boost controller designed for the Toyota GR Yaris equipped with an electronically controlled turbocharger. Installed directly between the factory pressure sensor and the original wiring harness, it optimises the boost pressure signal to increase turbo boost through the factory engine management system. The result is improved engine performance, increased torque, and quicker throttle response without the need to reprogram the factory ECU.

The Power Editor comes with preloaded HKS calibration data specifically developed for the GR Yaris, providing a simple plug-and-play installation. For users who require additional fine-tuning, the unit is compatible with HKS Easy Writer software, allowing supported calibration adjustments. A supplied bypass connector makes it easy to return the vehicle to the factory signal configuration without removing the complete wiring installation.

During HKS testing, maximum engine output increased from 235.6 PS to 248.4 PS, while peak torque rose from 355.4 Nm to 375.8 Nm. The highest recorded power gain was 21.7 PS, with reference boost pressure increasing from 148.1 kPa to 167.7 kPa, delivering stronger acceleration and enhanced power delivery throughout the rev range.

In October 1973, two talented and young engineers had a vision; to design and build high performance engines and components that major OE manufacturers could not, or would not, produce. HKS pioneered the Japanese aftermarket industry by delivering a host of exciting new products, including the first commercially available electronic turbo timer and boost controller. Other early products included piggy-back ECUs and sophisticated fuel management tools. HKS was clearly driving performance trends for Japanese vehicles forward!

Today, HKS is one of the world's most well-known brands and the obvious choice for you who builds a JDM car. In the assortment you will find everything from chassis products to exhaust systems and turbo kits. HKS is behind some of the coolest builds and professional drivers in the world, so when you choose HKS, you choose the best.
