The Efie Problems…What You Can Do About It!

Efie problems usually occur when you run your hho gas engine without warming it up. Other serious changes to fuel mixture can happen also if the sensor enhancer resistor setting is too high so that the average voltage setting of the oxygen sensor will increase resulting in open loop conditions. First of all, when talking about your regular oxygen sensors types, it applies to what they call a narrow band oxygen sensor where your average voltage is around 0.450 volt. This type of sensor is also characterized by the use of 1 to 4 wires connections.

The efie problems are prevalent during start ups based on what hho people are reporting online. Unless they wait for the engine to warmed up, then the efie begins to work better. As a matter of fact, a few reports say that if you apply the efie right away upon start ups, your engine will run rough. So how do you avoid it? Two things: put a toggle switch to control when to apply it. In one efie enhancer developed just recently, I saw a Utube video where the efie maker put an automatic delay circuit inside the efie itself.

A detailed efie problems are shown being fixed here in this video. The efie gadget has both a power switch to turn it on and a built-in delay circuit so that the oxygen sensor will wait for your engine to warm up. This prevents accidental rough engine starting and failure for the computer to go in close loop. Finally, he allowed the efie user to adjust the oxygen sensor voltage for optimum use. This strategy should be applied during efie selection before using it in your hho gas saver.

Notes:

Again, this is not an endorsement by ATS of the video suggested efie product shown here. We are just exploring all the possibilities to give you the choices for solving these efie problems.

Beware of efie enhancers when applied to wide band oxygen sensors. Unlike the old type oxygen sensors, its voltage reading borders beyond 1 volt. This requires a different efie sensor enhancer setting altogether. Proper efie enhancer setting will be discussed later.
