This is how the voltage stabilizer works.
The vehicle's ECU is highly dependant on all sensors that provide data and signals to coordinate different parts in different places of your vehicle. The vehicle's ECU can analyze if the voltage flow on your vehicle is accurate. What this VS does is enhance the voltage and stabilize it, so all the components in your vehicle such as audio, lamps, sensors and electronics work to their maximum potential. By stabilizing the voltage from the battery of your vehicle, the load of the battery is reduced, resulting in increasing engine performance.
