Volo FS3 Fuel Saver Chip/ECU Tuner for 2008 Jeep Grand Cherokee 3.0L 3.7L 4.7L 5.7L 6.1L

The FS3
The FS3 is one of our most powerful Dynamic Soft-Flashers. Operating at 20MHz with plenty of On-Board Memory, the FS3's 8-Bit CMOS microprocessor offers extended compatibility along with faster patching for safer, higher, and more consistent gains.

Gains
Average gains for the Grand Cherokee are 15-18% over stock MPG without losing power or torque.

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 FS3 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.
