Gzh Nitro OBD2 Performance Chip Tuning Box,diesel Regulator Plug & Drive Obd 2 + 35% More Power + 25% More Torque,fuel Optimization (Color : Red*Diesel car)

All it has is an led light that gashes when connected to the obd jack. Don't waste your money

Good tools

they don't work its just a flashing random light this unit has no way of connecting to your car's ECU

Do your research. this does nothing to help your car. the circuits are just flashing LED's

Not worth the bothering

Do not buy these. Plenty of people have reverse engineered them and they literally do nothing apart from blink the leds. Nitro OBD's chip does not embed any CAN transceiver, and is unable to communicate on the CAN bus.
