WORKING THEORY
An automotive oxygen sensor, also known as an O2 sensor, lambda probe, lambda sensor, lambda sond or EGO (exhaust gas oxygen) sensor, is a small sensor inserted into the exhaust system of a petrol engine to measure the concentration of oxygen remaining in the exhaust gas to allow an electronic control unit (ECU) to control the efficiency of the combustion process in the engine. In most modern automobiles, these sensors are attached to the engine's exhaust manifold to determine whether the mixture of air and gasoline going into the engine is rich (too much fuel) or lean (too little fuel).
This information is sent to the engine management ECU computer, which adjusts the mixture to give the engine the best possible fuel economy and lowest possible exhaust emissions.
If we alter the information delivered to the ECU we may affect engine horsepower.
This unit takes off the barriers applied by the ECU, it tricks O2 sensor signal, consequently delivers 10 % extra power plus noteworthy low end torque within the full RPM range without failed economy.
This Magnum device modifies voltage signals of oxygen sensor, indicating fuel lean signal, accordingly ECU lets more fuel to the injectors while the mass of free air is the same. Thus we can affect the air fuel mixture gaining more power, improving the efficiency of combustion and saving fuel. This add-on device delivers fuel-poor sign to the ECU, besides a limit value control is incorporated to avoid overflow and underflow.
