Overview

It enhances power and torque, improving engine response from low revs to redline. This tuner efficiently adjusts the ECU with improved signals from the Inlet Air Temp and Exhaust O2 sensors to support a richer fuel mixture under load, resulting in stronger pull, quicker acceleration, and better passing performance. It features add-on connectors with no permanent changes to factory ECU settings, allowing for easy removal. The tuner also aims to slightly improve MPG.

Show original supplier description

This performance module aims to unlock hidden power reserves by optimizing the ECU's fuel delivery. It works by intercepting and adjusting signals from sensors like the Inlet Air Temperature (IAT) and Exhaust O2 Sensor to create a more performance-oriented fuel curve, particularly when the engine is under load. This results in an 18% increase in power and torque, quicker acceleration, improved throttle response without flat spots, and potentially a slight increase in fuel mileage. The Smart-Tune-X features a dual-mode emission control feedback system and offers full adjustability through a high-resolution LCD display. Its Remap Correction with Auto Temperature Compensation ensures optimal performance across various conditions by utilizing a standalone 2-wire Inlet Air Temperature sensor for precise fuel mapping. The module also includes an in-built oxygen sensor control for emission-controlled models. It wires inline with existing harnesses, tapping into the Intake Air Temp and Oxygen Sensor (if present) and an ignition key activated +/- 12V power feed. The module itself is waterproof (though not submersible) and comes with a 10-year warranty. The setup uses add-on connectors, meaning there are no permanent modifications to the factory ECU, and the tuner can be removed at any time. The module's dimensions are approximately 5 3/4" x 2 7/8" x 1 1/2", weighing 0.77lbs with a 5' harness.
