How Does the X3 Module Work?

The X3  module takes the signals from your engine sensors, modifies them, and then sends optimized signals back to your vehicle's ECU. The X3 module adjusts the air/fuel ratio and modifies the secondarily timing curves to new performance settings.  In addition, our X3 module has an Oxygen Sensor control circuit integrated so that it can automatically set the signals going to your vehicle's ECU for power or fuel economy.
