Thousands 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 new FS3 Fuel Saver. This model is capable of producing higher and more consistent gains than the FS1.

Please read this description carefully before making a purchase.

The FS3 is our newest performance chip, based on the powerful VP12.

This model has been designed to tune your ECU to produce serious gains in fuel efficiency with no loss of power.

Like all of our Chips the FS3 is dynamic - which means the FS3 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 FS3 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.

Recommended modifications :
- K&N or equivalent non-restrictive intake

The FS3 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 FS3 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 FS3 will read the first few bytes of data from your ECU during calibration to determine which map to use.

Whats the difference between the FS2-HHO Ed. and the FS3?
The FS3 uses the same maps as the FS2, but with HHO routines removed. The FS3 is for those with standard vehicles not equipped with HHO. If you are using HHO, or intend to install an aftermarker HHO generator in the future, we recommend the FS2-HHO Ed.
