WHAT YOU SHOULD KNOW ABOUT MAP SENSOR'S AND EFIE SENSORS
Some vehicle's will require a Map Sensor and Some require EFIE Sensor (EFIE Sensors is common for Ford Products) depending on the vehicle. We have found with many experiments that you must use one or the other with the HHO, H2O system unless your vehicle has a carburator and is not fuel injected then these Products are not required
DUAL-EDGE MAP SENSOR ENHANCER (DEMSE)
CAUTION: This device may be used ONLY in conjunction with an Electrolyzer (HHO device) or a Vaporizer (H2O device) installed and functional.
ALTERNATIVE ENHANCER
A recent addition, this enhancer worked much better (in OBD-II tests) than the O2 Sensor method. The O2 Sensor method, on the other hand, worked great on OBD-I. Too early to withdraw absolute conclusions, but this is what indicates at the time of writing.
A STUPID LITTLE RESISTOR???
Let me start with a limiter: THIS DEVICE IS EXPERIMENTAL AND HAS WORKED ON OBD-II. It has been reported to also work on OBD-I. I don't think it works well for MAF (Mass Air Flow) sensors or Oxygen sensors because those rely on frequencies while this is a direct current device.
Now let's define some words.
When we say the word “computer” in reference to the fuel and emulsions control system, we're generally referring to the ECU or Environmental Control Unit. It is also sometimes called the PCM or other names. So we may be using the word computer and ECU interchangeably, although some cars have more than one computer. The ECU is what we're interested in when it comes to saving energy.
OBD means On Board Diagnostics – basically the engine computer system and a dictated set of performance sensors that are mandatory on all cars since 1996. OBD-I is pre-1996. Now we have OBD-II. They say it is mandatory for emissions control. I have come to realize that it's for the purpose of wasting gas. This “modern” system uses gasoline to cool down the engine and “control” the emissions, when patents and technology have been in existence for a century now to do all that without wasting energy (deteriorating the planet) and without building up sludge (aging your car real fast). Thus from now on say OBD means On Board BS.
“Potentiometer” (or “pot”) simply means variable resistor. For a long while I've been hearing about the use of some “resistor” to lean out the mixture. I've heard it was being sold on eBay and thought it was too good to be true. Because if it is so simple, then why do we need EFIE or D17 (various electronic devices that change or “translate” the pulses of the O2 Sensors)?
Well, I'm not at all sure why we need the complicated stuff... I tried this simple device here in a vehicle running OBD-II and it worked better than expected. While driving at 55 MPH I have dialed the MPG gauge up by as much as 77% just by turning the knob way down. The latest test results have averaged 59%.
BACKGROUND OF THE INVENTION - WHY IS THIS NEEDED
The simplicity of the background is this: we're using what some people refer to as “watergas technology”. Electrolyzers, water vaporizers, water injectors, hydrogen generators of all sorts and colors. As far as I know everybody in the industry shares the same problem on modern computerized cars, and here's a typical story: somebody installs a device and enjoys better fuel economy for a few days. Then after maybe half a tank or so, he calls or emails the developer and says: “Hey listen – your device stopped working – I'm losing mileage. I can see the bubbles coming out and all, but the performance has dropped!! I am losing the gains I had!” You know what it means when somebody is losing gains he's already got? It means there is some freaking suppression on the area! It needs to be detected and removed, either by handling or by disconnecting from the source of suppression.
Now let's get purely technical and examine what happens. You have enriched your car with something fantastic – water power of some sort. Hydrogen, water vapor, or both. As your computer senses a richer fuel it then reduces the amount of fuel being consumed, because you’re already running rich. So far so good because you don’t need as much fuel as before.
Now the problem shows its ugly face when we discover that the computer – your vehicle's computer – has been pre-designed to protect the vested interest of those who would like to see you waste fuel like crazy. While pretending to be your friends. This is an unproven theory of course, but your computer figures out that we've been enforcing fuel economy for a while and it says: “Wait a minute - somebody is probably doing something fishy here” - and it switches your car into “Limp Home” mode which means, between other things, a constant-rich (wasteful) mixture. What just happened? You’ve been enjoying good fuel economy for a while, but all of a sudden your gains are dropping and in some cases even going negative. That is, worse than before the installation. You computer has said: “Sorry buddy, we've just caught you cheating and we can’t allow that.” Here comes the counter-measure. Several inventions exist to lean the usage of gasoline back to where it was before you've lost gains, and in most cases even much better. The invention we're presenting here is not the only one, but is among the simplest.
To sum up, we’re going to use this invention to change the set points so that the computer is still active in “closed circuit” or “closed loop” mode. That is, it still senses the car's performance and it still controls the consumption of fuel as needed every little moment of driving – but the difference is that now we have totally changed the set points in your favor! Now you are going to enjoy the mileage gains and you'll get to KEEP THEM for a very long period of time.
HOW DOES THE MAP SENSOR WORK?
The Manifold Absolute Pressure (MAP) sensor signal is electrically used in a similar way to the use of Mass Air Flow (MAF) sensor signal (although internally it is built differently). It takes a 5 volt signal from the computer, and returns a lower directcurrent signal in accordance with the vacuum in the engine. A higher output voltage means lower engine vacuum, which is then calculated as “more fuel is needed”. Lower output signal indicates higher engine vacuum, which requires less fuel. It's not just fuel control though. The MAP senor signal gives the computer a dynamic indication of engine load. The computer then uses this data to control not only fuel injection, but also gear shift and cylinder ignition timing. In some cases it is even used to calculate changes in barometric pressure, to automatically adjust for different altitudes.
Some vehicle's will require a Map Sensor and Some require EFIE Sensor (EFIE Sensors is common for Ford Products) depending on the vehicle. We have found with many experiments that you must use one or the other with the HHO system unless your vehicle has a carburator and is not fuel injected then these Products are not required. Check with your Dealer on make of your vehicle.

Why An EFIE Is Needed
Fuel Injected Vehicles
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.
