Is the OBD Voltage Stabilizer for Fuel Saving in Cars Useful?

[DelArcher]

Automotive fuel-saving OBD voltage stabilizers are not useful as they cannot modify the core data of the vehicle's ECU. To reprogram a car's ECU, specialized computer programs and experimental models are required for data simulation. OBD fuel-saving devices can only receive and send signals and data but cannot decrypt the manufacturer's encrypted data. The function of an automotive OBD is to monitor the working conditions of the engine's electronic control system, vehicle functional modules, and exhaust treatment system during operation. If a system in the car malfunctions or the exhaust emissions exceed standards, the fault light will trigger an alert. The OBD device can simultaneously monitor multiple systems and components in the car, including: the engine, catalytic converter, particulate filter, oxygen sensor, emission control system, and fuel system.
