Volo FS2-HHO - Soft Fuel Remap

volo chip fs2 hho

Product Description:

HHO 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 in the Volo line up - The FS2-HHO Edition! (View Product)

Please read this description carefully before making a purchase.

The FS2 is our newest 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.

When using HHO as a fuel supplement, the FS2 will adjust fuel delivery and timing to optimize efficiency.

The FS2 is a vehicle specific, custom programmed 20MHz Microcontroller. It utilizes its high speed serial input/output to communicate directly with the ECU through the OBD-II port.When HHO is disabled, the FS2 will automatically re-adjust and switch to highly efficient, non-HHO enhanced maps. 

Recommended Modifications:

- K&N or equivalent non-restrictive intake
- HHO (Oxyhydrogen) Supplement Generator for maximum gains.

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 Volo 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.

Whats the difference between the FS1 and the FS2-HHO Ed.?
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.

What is HHO and how does the FS2-HHO Ed. help?

HHO gas, also known as oxyhydrogen can greatly increase the fuel efficiency of cars in which it is used. HHO gas is created through a simple process of electrolysis - the car does not run just on HHO but rather a hybrid of gasoline and HHO which powers the car. HHO has been shown to increase fuel efficiency by as much as 93% in some cases.

There are many HHO kits available online and installation does not require any specialized knowledge.

The ECU is the key to getting the most out of your HHO installation. EFIE's and O2 sensor modifications are inelegant and insufficient when it comes to getting your ECU to work with HHO.

The FS2-HHO Ed. has been specifically designed to solve the problem with late model ECU's by patching fuel mixture values on the fly. The FS2 is the best solution to a complex problem.
