EFIE known as Electronic Fuel Injection Enhancers are used to help regulate or adjust the voltage on an oxygen sensor. Most of these dual EFIE circuits or EFIE circuits are to be purchased for water4gas plans or other comparable HHO plans. This module or circuit is usually added between the oxygen sensor and ECU or electronic control unit. This circuit is often added on some vehicles because when an HHO kit is installed the exhaust is so clean that the voltage produced by the O2 sensor can cause the computer to compensate by adding more gasoline to the mix thus reducing gas mileage. An HHO EFIE circuit adjuster is used to aid in this situation. Buy a EFIE Kit to ensure you hydrogen HHO generator system is working at peak efficiency.
