The ECU is the main component that bridges the air ride suspension and the NSHIFTED App. It has the ability to interpret the user input on the App and send it to the air suspension system, as well as get data from the air suspension sensors and send it to the App.
The NSHIFTED Pressure bundle combines the power of the ECU with Pressure Sensors, therefore offering a variety of extra features that rely solely on sensors, in addition to the controlling of the air suspension and the rest of the ECU features.
The pressure sensors unlock various features of the NSHIFTED management that rely on air ride pressure readings, like: Pressure gauges on the App, Presets, Auto-Leveling and more. Five (5) or three (3) pressure sensors can be installed, depending on the air suspension setup.
