The FS2
The FS2 has been specifically tuned for the needs of HHO generator equipped vehicles. A dynamic 20MHz microprocessor, the FS2 will consider O2 levels, engine speed and load, intake air temp. and volume, along with many other variable to calculate HHO output and automatically adjust fuel delivery and timing for maximum gains.

Gains
The FS2 was designed to help your ECU accept HHO as a fuel supplement. Its output is dependent on the efficiency of your HHO system. When HHO is disabled the FS2 will automatically switch to its high efficiency, non-HHO maps and continue to produce gains of 15-18% over stock.

Installation/Use
Installation takes about 15 minutes and requires no special skills. Once installed, press the RESET button to calibrate and you're done!
The FS2 does NOT include an OBD-II connector. It connects directly to the OBD-II port's data lines. OBD-II scantools will not interfere with operation.
