Overview

It aims to increase horsepower, torque, and acceleration while also improving fuel mileage and top-end speed. The chip interfaces with the vehicle's Intake Air Temperature and Oxygen sensors to optimize fuel delivery and performance.
Show original supplier description
This module enhances your vehicle's performance by adding a claimed 18% extra horsepower and improving torque response throughout the usable rev range. It works by efficiently delivering advanced signals from the Inlet Temp and Exhaust Oxygen sensors to support a richer Air/Fuel Ratio mixture under load, resulting in stronger pull, quicker acceleration for highway merges, and more confident passing. This performance chip offers a hassle-free installation process, requiring minimum electrical and mechanical skill, and can be wired in by the user without needing to contact a professional mechanic. The Smart-Tune-X does not make permanent changes to the factory ECU fuel mapping software and can be removed at any time, returning the vehicle to its stock settings. It features a high-resolution LCD display for full adjustability and includes a Remap correction with Auto Temperature Compensation (ATC) and an in-built oxygen sensor control for emission-controlled models. The module is also waterproof, though not submersible. The unit taps into the Intake Air Temp and Oxygen Sensor (if present) and requires an ignition key activated +/- 12V power feed. It comes with a 10-year warranty.
