Show original supplier description
It connects directly to your vehicle's Inlet Temp sensor and Exhaust Air Fuel Sensor harness, allowing it to remap the fuel trim for a richer air-to-fuel mixture. This results in a noticeable increase in horsepower and torque across the entire RPM range. Installation is designed to be straightforward, with mechanical-minded owners able to complete it within approximately 45 minutes using basic wiring tools. The chip allows for fine-tuning via a remote adjustment knob, enabling you to customize performance to your preferences. It maintains factory drivability while delivering robust, usable horsepower gains and improved engine response. The system also allows for a return to original factory settings with the flip of a switch, ensuring reliability and service life remain unchanged. It also overrides the downstream AF Sensor's signal to further enhance performance. This product aims to unlock your Toyota C-HR's full potential by overriding manufacturer-imposed limitations, leading to more responsive acceleration and improved overall performance. Claims include a 15% increase in horsepower and torque, a 22% faster acceleration throughout the RPM range, and a potential 6% improvement in fuel mileage. It also aims for a higher top-end speed and improved throttle response without flat spots.
