Enhancements with DKU Performance
This Toyota Yaris 1.4 underwent a professional ECU remap alongside a hydrogen carbon clean to restore and enhance overall engine performance. The remap improved throttle response, torque delivery and drivability, resulting in a smoother and more responsive driving experience across the rev range.

The hydrogen carbon clean removed built up deposits within the engine, helping to restore efficiency, improve combustion and support better fuel economy. Together, these upgrades delivered a noticeable improvement in engine smoothness and responsiveness.

To further complement these gains, options such as a custom Toyota Yaris Exhaust or full Toyota Yaris Exhaust System from DKU Performance can significantly improve exhaust flow, reduce back pressure and enhance both sound and performance.
