The A'PEXi Air Flow Converters work by intercepting the signal between the car's air flow meter and the ECU. The Air Flow Meter is the device that tells the ECU how much air is entering the engine so that the ECU can add the correct amount of fuel.

The ECU calculates the proper ratio of fuel to air for a stock, unmodified engine. Certain engine modifications can cause the dynamics of the engine to require more fuel. In this case, there are two common options for modifying the amout of fuel being input into the engine. One can either install larger injectors or increase the fuel pressure to the stock injectors is increased.
