The NDSII Lite is a diagnostic and monitoring app for measuring fuel consumption and engine temperature.

To connect with the NDSII Lite, you need to purchase a Bluetooth diagnostic adapter that is compatible with the NDSII Lite. The current version of the app supports only ELM327 diagnostic adapters.

The ELM327 diagnostic adapter is a Bluetooth adapter that allows you to send commands to your car's ECU to measure the following:

The temperature of the engine, the temperature of the car's exterior and interior, the current fuel level, the amount of consumption, the amount of water and oil in the car's engine, the car's speed, the number of driving cycles, etc.
