OBD2  fuel saver device improves fuel efficiency in vehicles by modifying the signals sent to the engine control unit (ECU) through the OBD2 port. Here’s a general idea of how the OBD2 fuel saver device works:

1. Signal Modification: These devices intercept signals from the vehicle’s sensors that relate to fuel injection, air-fuel mixture, ignition timing, or other engine parameters. They may modify these signals before they reach the ECU.
2. Optimization: The modified signals are intended to optimize engine performance and fuel efficiency. For example, they may adjust the air-fuel ratio to a more efficient level or optimize ignition timing for better combustion.
3. Efficiency Monitoring: It monitors the driving behavior and engine performance in real-time. They may adjust their optimization algorithms based on factors such as vehicle speed, throttle position, and engine load.
4. Installation: Installation typically involves plugging the device into the vehicle’s OBD2 port, which is usually located under the dashboard. The device may require configuration or calibration, depending on the model.

It has the capacity of saving you up to 15%-30% of fuel consumption, while taking you more distance with full engine power and efficiency. This means that for every full tank of fuel you buy, you get to save about 10Litres to 15Litres. When you multiply this by how many times you fuel in a week or Month, you will definitely feel the huge relief of financial burden you have achieved by just installing this SMART FUEL SAVER.
