In the early days of HHO gas generator technology, many vehicles were unable to have fuel savings higher than 30% due to the strict parameters of their computer management systems. These cars have electronic fuel injection with advanced ECUs (Engine Control Units with Euro modules IV and V) and some would simply not allow fuel economy to improve beyond certain programmed values.

As HHO Gas Generator technology advances, more vehicles are able to benefit despite these ECU limitations. The new HHO generator EFIE Chip (HEC) is one of the newest products to address and solve the limitations of many modern vehicle ECUs.
With the new HHO HEC your fuel savings can go up significantly. When using hydrogen gas as a fuel supplement, the HEC will adjust fuel delivery and timing to optimize efficiency. When HHO Gas Generator is disabled, the HEC will automatically re-adjust and switch to highly efficient, non-HHO enhanced maps.

What is a HHO EFIE Chip (HEC)?
The HEC is a chip, with a 200 mhz microprocessor, It utilizes its high speed serial input/output to communicate directly with the ECU through the OBD-II port It has been specifically developed and tuned for the needs of HHO Gas Generator equipped vehicles. The HEC is dynamic - which means the HEC will consider oxygen levels in the exhaust, along with engine speed and load, intake air temperature and volume, and many other variables to determine the most efficient fuel delivery rate and timing at up to 256 separate load points.

The HEC is a vehicle specific, custom programmed 20 MHz microcontroller. It utilizes its high speed serial input/output to communicate directly with the ECU through the OBD-II port.
The HEC is compatible with factory equipped Turbo/Superchargers, diesel engines, Flex-Fuel, & HHO generator supplement systems. It is NOT compatible with hybrid engine options, propane, or natural-gas.

How does the HHO EFIE Chip (HEC) Works?
Inside every ECU there is a three dimensional table of values called a Map. This table tells your fuel injectors exactly how much fuel to deliver based upon current air temperature, density, engine speed, throttle position, and other variables.
From the factory, the map is generic and designed to provide a sluggish, no-surprises style of driving that suits a wide range of drivers. It is especially ignorant to the benefits of HHO Gas Generator systems and their ability to burn fuel at a much greater air to fuel mixture ratio than usual.
HHO EFIE chip corrects this problem by providing a pre-programmed and highly tuned map for the ECU to reference. The tuned map contains a set of variables that directly allow a better fuel efficiency. When the ECU attempts to read specific factory settings, the flash chip patches the factory value with one from its tuned Map.
In this way, when the HEC chip recognizes an HHO Gas Generator system is operating, parts of the factory map are temporarily replaced with improved variables from the tuned maps. This technique safely unleashes your engine's ability to use less fuel and it doesn't void the warranty.
And yes, it's easy to remove and restore the computer to factory settings when desired.
How to Install?
Simply locate the OBD-II port, connect the HEC Chip to four wires found BEHIND the port, and you're done. Bring the vehicle up to operating temperature and then press the reset button to start saving fuel.

Whats the difference between the normal Chips and the HEC?
The HEC is much faster than the regular Chip, which means faster & more consistent gains. The HEC also sports more memory than the regular Chip, so we are able to include more HHO gas specific coding.

HHO PLUS developed an HHO system that allows you to reduce the fuel consumption in your car at a very low cost. It is smart to use your normal fuel mixed with the oxyhydrogen gas/brown gas generated in your vehicle in a process called electrolysis of water. Electrolysis of water is the breakdown of water, H2O, into two atoms of hydrogen gas -H2+H2 and oxygen -O2 due to an electric current being pass through the water. The HHO gas produced is then directed toward the engine's combustion chamber and through the air intake manifold, where it mixes with your typical carbon-based fuel, petrol, diesel, or LPG and they're both burned. That allows your carbon-based fuel to burn properly, increasing the combustion efficiency. This reduces fuel consumption and the amount of pollutions released in the exhaust. You will be able to install it in your car without the help of a mechanic because the HHO gas generator is simple to use.

DOWNLOAD: NASA Research on HHO PLUS Hydrogen HHO Gas HHO KIT has shown that Hydrogen supplemental fuel engines require less fuel and produce less carbon emissions.

The experiments were carried out to evaluate the impact of the addition of fuel saver (hydrogen gas+oxygen obtained electrochemically from the HHO gas generator dry cell kit) to the air intake manifold of petrol/diesel/LPG engines. The research shows that the addition of a real fuel-saving device improves the combustion fuel efficiency process due to the different combustion properties of hydrogen in comparison to conventional fuels.


Our HHO Gas Product's Advantages

1. Reduces your fuel spending by up to 30%. This is valid for both highway and town (city) driving conditions.

2. Increases the power and performance of your car. The more fuel you burn, the more the engine gets rattled up and wrecked. Switching to supplemental HHO PLUS Hydrogen HHO Gas will enhance the power and performance of your car.

3. Reduces CO2 emissions by eliminating pollution and other harmful residues that our car engines produce. What's wrong with also doing something good for the environment, besides saving money?

4. Reduces the temperature in the engine. Also, it improves the engine's life span since it burns fuel in a much cooler state.

5. Removes the carbon residues inside your engine and prevents future carbon deposits.

6. Decreases noise and vibrations in the engine. The HHO PLUS Hydrogen HHO Gas generator dry cell kit will have an effect on the combustion cycle. The engine will sound much quieter than it was before. This is due to a higher combustion efficiency in your car.

7. Increases the life span of your engine.

How Will HHO PLUS Hydrogen HHO Gas HHO Generator Kit Work in Your Car?

Inside the engine there are pistons moving rapidly up and down at a constant rate, generating power for the car. When a piston lowers, it creates a vacuum which sucks in fuel and air (intake); when it rises, it compresses the fuel (compression), and the spark plug ignites it (power).

An engine will ideally only fire the piston when it has completely reached the top of the combustion chamber. However, most engines fire earlier and don't burn the fuel completely. This creates inefficiency, increases consumption, and creates pollution.

When the HHO gas is mixed with your fuel, the pistons will be able to compress it completely before it ignites, and the extra Oxy-Hydrogen - HHO gas allows the fuel to burn more efficiently, reducing the amount of waste (emissions). This also adds a bit more power to the engine, which increases its efficiency and improves your km per liter.

Converting your car to the HHO gas Oxy-Hydrogen Generator Kit supplemental fuel system is reversible, and you can always put it back to your usual fuel without any problem or decrease in value.

HHO stands for 2-parts Hydrogen & 1-part Oxygen. When 2 Hydrogen atoms are bound to 1 Oxygen atom, you have water, but when you separate the atoms from each other, you have Hydrogen & Oxygen mixed gas. The correct term for this gas is Oxyhydrogen.

There are many names for this gas mix, such as browns gas, green gas, Hydroxy, Di-Hydroxy and water gas. The wonderful thing about this gas is the byproduct, which is water. There is no smog or fumes that are plaguing our planet today.

HHO (Oxyhydrogen) will combust when brought to its autoignition temperature. For a stoichimetric mixture at normal atmospheric pressure, autoignition occurs at about 570 °C (1065 °F). The minimum energy required to ignite such a mixture with a spark is about 20 microjoules. At standard temperature and pressure, Oxyhydrogen can burn when it is between about 4% and 95% hydrogen by volume. When ignited, the gas mixture releases energy and converts to water vapor, which sustains the reaction: 241.8 kJ of energy (LHV) for every mole of H2 burned. The amount of heat energy released is independent of the mode of combustion, but the temperature of the flame varies. The maximum temperature of about 2800 °C is achieved with a pure stoichimetric mixture, about 700 degrees hotter than a hydrogen flame in air. When either of the gases is mixed in excess of this ratio, or when mixed with an inert gas like nitrogen, the heat must spread throughout a greater quantity of matter and the temperature will be lower. (Source: Wikipedia) Okay, so now you know what HHO is, but how is it made? By a simple method called electrolysis, a method first recorded in 1800 by William Nicholson and Johann Ritter. Electrolysis involves the passage of an electric current (DC) thru electrodes. As we know, batteries have a positive and a negative.

A pure stoichimetric mixture may be obtained by water electrolysis, which uses an electric current to dissociate the water molecules:

Electrolysis: 2 H2O → 2 H2 + O2
Combustion: 2 H2 + O2 → 2 H2O (Source:Wikipedia)

With electrolysis, you have 2 types of electrodes called cathodes and anodes. The cathodes are positively charged; the anodes are negatively charged. The electrolysis process causes oxidation (rust), which can wreak havoc in an HHO generator with corrosive materials.

Water, by itself, is not a good conductor of electricity, so an electrolyte is commonly added to the water to allow electric current to pass through the water, breaking it down into HHO. There are many types of electrolytes, and each has pros and cons. Most manufactured HHO generators are designed for a particular electrolyte. We discussed what HHO is and how it's made, but how does it help?

"Modern gasoline engines have an average efficiency of about 25 to 30% when used to power an automobile. In other words, of the total heat energy of gasoline, 70 to 75% is rejected (as heat) in the exhaust or consumed by the motor (friction, air turbulence, heat through the cylinder walls or cylinder head, and work used to turn engine equipment and appliances such as water and oil pumps and electrical generator), and only about 25% of energy moves the vehicle." Source: Wikipedia

Adding the HHO gas to the air intake increases efficiency. It creates an atmosphere that allows the gasoline to burn more cleanly and efficiently, and the engine requires less fuel whilst operating more smoothly and producing less carbon monoxide and dioxide.

"Reduce pollution and gas consumption AND run smoother with HHO."
