ecoOBD2 Plug & Drive Economy Chip Tuning Box

I'm selling an ecoOBD2 Plug & Drive Economy Chip Tuning Box for gasoline cars. It's designed to reduce fuel consumption and save fuel by 15%. This device plugs into your car's OBD2 connector and remaps the car's computer ECU after about 200 km of driving. It comes with a 2-year warranty.
