The FS3 has been
specifically tuned for the needs of non-HHO equipped vehicles that want
performance increases that will increase fuel efficiency.
The FS2-HHO has been specifically tuned for the needs of HHO generator equipped
Both are dynamic - which means they 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.
When HHO 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 Microcontroller. It
utilizes its high speed serial input/output to communicate directly with the
ECU through the vehicles' OBD-II port.
Note: According to Kevin, at Volo Sales and
Support, :"Unlike ECU ROM chip replacements or
permanent ECU flashing, the Volo Chip makes no changes to the ROM itself and
does not require opening the ECU. It will not void your factory warranty."
