How does the EFIE chip work?

The engine's sensors, intake, and exhaust are often old, and with HHO kits, the EFIE chip is recommended to achieve the best-desired results with many advantages.

Standby LED blinks every 5-10 seconds. There is no signal from the vehicle’s computer. The device may not enter standby on some vehicles in which the ECU remains active after engine shut-off. This is normal and will not adversely affect the operation.


Power and Link LEDs are solid green. Auto Calibration tuning and ECU LEDs are solid or flashing. This indicates the device is connected and functioning correctly.
