11. Will the water in the device freeze in winter?
No, if you add about 20-25 % of alcohol (isopropylic) to the reservoir solution to prevent freezing in winter months.

12. What if I don't use Distilled water in my generator?
Distilled water is basically pure water. Other kinds of water like tap water, mineral water, pond water, sea water, etc., will work but they will also quickly cause the electrolyte to become "muddy" due to the minerals and impurities in the water. The muddy electrolyte will build up on the generator plates and serve as an insulator causing HHO gas production to suffer. The same is true with many other kinds of catalyst, especially any catalyst containing sodium, like baking soda or sodium hydroxide. Sodium will fast contaminate the electrolyzer plates and cause the unit to become ineffective.

13. Can the hydrogen generator explode?
No. The hydrogen production is made on demand. You will have hydrogen only when your car is moving. Unlike pressurized gas tanks, there is only a little amount of hydrogen pressure in the system.

14. If I have concerns is there any tech support for my HHO Generator?
Tech support is provided for your HHO Generator (

15. Is there any type of warranty that comes with my HHO Generator?
Yes, a 1 [one year 100 % warranty] for parts and unit repair or replacement

16. In case of an accident will the Hydrogen Generator explode?
Never, all you will have is water and electrolyte on the ground

17. Can we use the Hydrogen Generator on a power generator?
The Generator can be applied on any power generator

18. What is the products life?
To date we have devices sold for several years still functioning.

The HHO Cell Revolution is Here!

The first worldwide available OBD HHO Fuel Cutter Enancher, with Programmable Digital MAP/MAF  & O2 Oxygen Sensor trimmer,full controlled in realtime by OBDII Scan Tool Pro and with 4 Programmable Presets, Automatically recalled from OBD II veichle speed!

Many HHO manufacture of electronics tuning, offer a lot of different analog MAP/MAF and O2 sensor accessory for Tuning the HHO Dry Cell system. All of this devices are manually and analog setting, by simple hardware trimmers or potentiometers. The main problem for best tuning the HHO System, require the final test with one professional OBD II Scan Tool, that can reconize or ble to display the all basic OBD features. Only with one external OBD II Scan Tool analizer is possible fine pitch the all MAP/MAF and O2 sensor, because the TRUE vale is returned back from the ECU and the user is able to fine pitch the sensors. Without the external OBD II Analizer, the all HHO Tuning are made under a teoretically setting, but you never know if the Fuel mixture is optimized or not.

After this Teoretically analog setting is done with the other analog devices, remain always one big issue, you have ONLY ONE Global setting, but this setting will be never match with the speed or the current status of your car!

For resolve this big issue, on the HHO OBD FC-Fuel Cutter we have implemented 4 programmable setting and each Preset will be Automatically recalled on the current Speed status of the Car!

This mean: when you drive slow, the first Preset will be recalled and will fine Tuning your MAP/MAF and OS Sensor, when you drive more Fast,  the next Preset will be recalled and new Fine Tuning is sent to the all sensors. This for the all 4 Available Presets, all will be recalled Automatically as you drive, with the FULL control of the al setting and Fuel save under your eyes!

HHO OBD FC-Fuel cutter is much more: We have implemented the 3 Basic Gates: When the Coolant Temperature, the Veichle speed and Engine Speed match to the Saved Value parameters, the Gates turn to ON mode and the all MAP/MAF/O2 Values are sent to the all sensor!

New ideas, features or functions? No problem! HHO OBD FC Fuel cutter is Ready to LOAD new software application, tools or updates direct from the embedded SD Card Slot! Just download the new update file, copy on one standard SD card, insert on the HHO OBD FC Slot and Load it! Finally one complete HHO OBD tool that can never to be Obsolet as the other traditional Analog HHO Tuning Accessory.

    1. What does HHO stand for?
    HHO consists of two elements Hydrogen and one part Oxygen. The enhancement of the Oxygen molecule makes HHO more combustable compared to pure Hydrogen.

    2. What amount of fuel efficiency will I get?
    Most users have economies from 20 to 30 % in fuel consumption. There are cases of higher outcomes.

    3. What advantage does HHO gas present when used as an internal combustion engine supplemental fuel?
    There are many benefits. HHO gas decreases fuel consumption by increasing the octane level and forcing the base fuel to combust more completely and efficiently. Higher octane result in increased horsepower. Higher octane, increased horsepower and efficient base fuel ignition is equivalent to much more km per liter. HHO fuel in fact helps to additionally clean carbon deposits inside the engine. HHO exhaust emissions are pure water. So, you conserve fuel, save money and save the environment.

    4. Is a hybrid fuel system more prone to rust or corrosion?
    No. The fossil fuel [gas or diesel] produces enough heat during combustion to vaporize the HHO as it turns back to water and leaves the exhaust system.

    5. Can this system enhance my performance?
    Yes, the injection of HHO into your internal combustion engine will help in cleaning the internal parts as the engine runs. It will boost the torque and horsepower and minimize the hydrocarbon pollutants presently being released into the air through your exhaust. Hydrogen combusts faster and cleaner than gas or diesel inside your engine. This makes your vehicle run smoother, longer, cooler, and more efficiently than in the past.

    6. Does it work with Diesel, Petrol or GPL vehicles?
    Yes, it functions with all vehicles with internal combustion engines.

    7. Does the hydrogen generator cause any short or long term harm to my engine?
    No, the hydrogen generator does not cause any harm to the engines.

    8. Why don't the auto manufacturers launch this technology on current vehicles?
    While fuel prices were low there was little financial assistance for this system. The Stan Meyers patents would grant the public control over their own energy because when optimized or developed from the ground up to take advantage of this innovation vehicles could run on 100 % water. Neither the oil companies nor the government wants to witness a multibillion dollar industry wiped out. The oil firms are reported to make more profits than any other industry in the world.

    9. What type of routine maintenance is required?
    Filling the Tank with Distilled water as required. Every 1000 km you are going to need 1 liter of water. Every three to six months basing on amount usage, it is recommended to drain and flush the device and replace with fresh distilled water and electrolyte catalyst.

    10. What is the electrolyte used?
    The best electrolyte is KOH (Potassium Hydroxide), Very cheap and easy to find.
