Efie Info …How important for Your HHO System?

This efie info is a must if you are installing a hho system in your car. Why? Because not all gasoline engines have the same types of oxygen sensors. Remember: We are talking about fuel injected gas engines here. If you have a carburated engine then this is not for you.

Whenever we talk about efie info, we are dealing with a efie device to alter the oxygen sensor reading during the time hho gas is mixed with your fuel. Problem here is after you got the hho generator installed, you have to figure out how to connect the oxygen sensor wirings? As you will see, oxygen sensor could have a single wire, 3 wires or even 5 wires or more. Our objective here is to find the oxygen sensor signal wire and that is what we need to connect to the efie device.

As longs as your gas engine has 4 wires or less, this efie info should be used: find which wire is the SIGNAL wire and that is the wire you are looking for. You can confirm that by using a volt meter. When your engine is running at idle (after 10-15 minutes of warmed up), that signal wire should read between 0.1volt to 0.9volt. And that reading is fluctuating all the time between those 2 voltage and they are not suppose to pass 1 volt.

It does not matter what color of wire it is as long as there is voltage oscillation, that is your SIGNAL wire. Shown here below is a Utube video showing a hho system being monitored by scangage and a efie device.

This test assumes that the efie is used on a 4 wire or less oxygen sensor. If the engine has 5 wires of more, the test for the oxygen sensor signal wire is completely different. For the meantime, before buying your efie device, make sure the efie vendor will guarantee to you that it will work on a 5 or more wires oxygen sensor if your engine has those types. Otherwise, ask for a complete instruction on how it is done. Failure to do this can make your efie useless. I hope this efie info has helped you.

Another Efie info TIP:

1.) The 5 or more wires oxygen sensor is called wide band oxygen sensor
2.) On some imports, wide band oxygen sensors could come in 4 wires. Make sure to check your vehicle dealer parts or ATS before connecting your efie device to your oxygen sensor.
