Fuel injected vehicles will need to condition the signal from the oxygen sensors to get the maximum gains from your HHO Electrolyzer. You can get an excellent device for this purpose by clicking on this link.

Electronic Fuel Injection Handler

Fuel injected vehicles need an Electronic Fuel Injection Handler (EFIE) for all oxygen sensors upstream of the catalytic converter. Installing a modern electrolyzer to your engine will cause additional oxygen to appear in the exhaust. The computer will then add gas trying to "correct" this desirable condition. An EFIE is needed to compensate for this, and therefore achieve the full fuel savings available. For more information please visit us at:

Electronic Fuel Injection Enhancement & Hydrogen Generation

I think that the Hydrogen Generator series on my website is about played out. Everyone is aware of the importance of the Hydrogen Generator to maximize your additional miles from a gallon of gasoline but not everyone is aware of how important the EFIE ( pronounced E-fy ) is to the Hydrogen Generation System. Frankly [...]

How To Build A Simple Working Hydrogen Generator

This video which I am going to try and add to this post shows how to build a simple Hydrogen Generator and what struck me was that you can generate enough Hydrogen/Oxygen and Vapor and add it to a bottle of tap water. I have pulled this from YouTube and wanted to share it with [...]

A Hydrogen On Demand System Part Two

Continuing on with the elements of a typical Hydrogen On Demand System, lets talk about some of the other sensors. The EFIE is a common addition to the Hydrogen Booster and is an absolutely necessary addition if you do not have these other Electronic Enhancers like a MAP sensor or MAF sensor. The booster [...]

An Alternative To The Fuel Injection Enhancer, The EFIE.

Here is some additional information for an alternative to the EFIE, not to say that the EFIE doesn’t work really well. But there are some other alternatives which it wouldn’t hurt to view and I will bring you some of them in the next few days. This will be the first alternative.
A recent addition [...]

Fuel Injected Vehicles

Fuel Injection Basics

Fuel injected vehicles use a computer and sensing devices to sense and maintain the correct air/fuel ratio. One of the key sensing devices is the oxygen sensor. Fuel injected vehicles have one or more oxygen sensors installed in the exhaust stream. The computer extrapolates what the air/fuel ratio is based on the amount of oxygen in the exhaust, as reported by the oxygen sensor.

When a fuel saving device is installed, such as a hydroxy electrolyzer, the petroleum based fuel is burned more completely. One of the results of this is that there is more oxygen (and less unburned hydrocarbons) in the exhaust stream. This is a good thing, and is in fact, what we are trying to achieve. However, the computer will perceive this condition as a "too lean" air/fuel mix. In other words, what is now a desirable condition in the exhaust, will be interpreted as "not enough gas", and the computer will direct the fuel injectors to increase the amount of gas being pumped into the engine.

The result is that the oxygen sensor and computer prevent efficient combustion from occurring!

The Solution
The oxygen sensor "tells" the computer what the oxygen content is by providing a voltage on it's signal wire between 0 and 1 volt. 450 millivolts (.45 volts) means that the fuel/air mixture is correct. Higher values means the mix is rich (has too much gas), and lower voltages means the mix is lean. By adding voltage to the sensor's output, we can compensate for the additional oxygen in the exhaust.

The Electronic Fuel Injection Enhancer (EFIE) does exactly this. It adds a floating voltage to the top of whatever the oxygen sensor is putting out. It has an adjustment that allows you to control, to within a few millivolts, the amount of this added voltage. This allows the computer to be unaware of the additional oxygen content of the exhaust, and the electrolyzer can now achieve it's full potential in fuel savings.

Most cars have oxygen sensors both before and after the catalytic converter. The ones downstream from the converter do not need to be treated. Their data is used to determine when the converter has gone bad, but are not used in the air/fuel calculations. EFIEs are only needed for all upstream oxygen sensors.
