The NEW! Volo FS3 Fuel Saver Circuit - FS3 (released 8/09) Introductory price of $89.95
This circuit works by an exclusive process of "Dynamic Soft-Flashing" the ECU.
The new FS3 was specially designed to SAVE MPG without the addition of any HHO booster.
Ships in 1 to 2 days. We burn them here at Hydrogen Garage.
Check availability for your Make, Model, Year car or truck.

Save money at the pump! Your car will run better, more HP at leaner settings.

How does it work?

The Volo FS3 Chip works by an exclusive process of Dynamic Soft-Flashing the ECU.
Each DSF Fuel Saver III comes programmed with a highly tuned map and a set of EPROM
addresses that directly affect fuel efficiency. When the ECU attempts to read the specific EPROM address,
the Volo Chip patches the factory value with one from its tuned map.

Built on the same platform as our popular VP12, the FS3 utilizes the same exclusive patching algorithms
to increase fuel efficiency across the map by up to approx. 10% to 18%.

Easy Installation!
Locate the OBD-II port, use the included connectors, and you're done.

You have nothing to lose!

Hydroxy gas enthusiasts swear by our time tested FS1. After the recent 4.3 patch, we've come close to the limitations of the FS1's hardware. So we've taken your feedback and suggestions, along with the powerful VP12 hardware, to build the newest - The FS2! New introductory sale price - $89.95!
Check availability for your Make, Model, Year  car or truck.

The FS2 is the latest performance chip, based on the powerful VP12. This chip has been specifically tuned for the needs of HHO generator equipped vehicles. The FS2 is dynamic - which means the FS2 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. Your Satisfaction is Guaranteed! or your money back, just return the circuit un-damaged and well will refund your money if your not satisfied! You cannot go wrong or lose. An easy 15 to 30 minute install is all it takes. Your OBD II port is free to use with the FS2. Also works with pre exsiting EFIE's and MAP/MAF adjusters. Volo Install Video

When using Hydroxy gas as a fuel supplement, the FS2 will adjust fuel delivery and timing to optimize efficiency.
When your Hydrogen Booster is disabled, the FS2 will automatically re-adjust and switch to highly efficient, non-HHO enhanced maps.
The FS2 is a vehicle specific, custom programmed 20MHz Micro controller. It utilizes its high speed serial input/output to communicate directly with the ECU through the OBD-II port.

See a Hydrogen Cell and Volo installed on a BMW Z3 Roadster. Continuous test results - 25% increase in MPG and also more horsepower and buy the cheaper gas, makes no difference. BWM recommends the higher octane premium fuel. Now with the added 120 octane hydrogen and oxygen, you don't ned the premium fuel.

Recommended modifications :
- K&N or equivalent non-restrictive intake
- HHO (Hydroxy Egas) Supplement Generator for maximum gains.
-  Cells :    B3 Cell, Clear Ed Cell, or JoCelleRator or a
7 plate Circulating Cell, 13 plate Circulating Cell
- Scangauge II ($160) For monitoring your MPG, engine temps, road mileage, volts, MAP, Lode, etc, etc. Monitor as you drive! Will also clear your codes for you!

The FS2 is compatible with factory equipped Turbo/Superchargers, diesel engines, Flex-Fuel, & HHO supplement systems. It is NOT compatible with hybrid engine options, propane, or natural-gas.
Is this the right one for my engine?
The FS2 has room for up to 8 performance maps, which we use to cover different engine options for a particular vehicle. For example, the 1999 Ford Mustang Chip will be compatible with both the 3.8L V6 and the 4.6L V8. The FS2 will read the first few bytes of data from your ECU during calibration to determine which map to use.
What's the difference between the FS1 and the FS2-HHO Edition?

The FS2 is much faster than the FS1 which means faster & more consistent gains. The FS2 also sports more memory than the FS1, so we are able to include more HHO specific coding.
The FS2 is legal and not an illegal product. It is not flashing your ECM's rom memory. It takes data from your ECM's ram memory.
Easy Installation, only 4  wires! Locate the OBD-II port, use the included connectors, or solder and you're done. Connects behind your OBD II connector's wires. You can still use the OBD II plug for any accessory, including the most excellent engine on board monitor, the Scangauge II.
ATTENTION INTERNATIONAL CUSTOMERS : Please verify your vehicle is OBD-II compliant before making a purchase. 1996-2009 Cars and trucks are OBD II. Will not work with OBD I ( 1987-95) cars.
