The NitroOBD2 is a plug-and-drive device designed to help reduce fuel consumption and lower emissions. It is easy to install and connects directly to the vehicle's OBD2 port, making it compatible with most vehicles manufactured from 1996 onward. The device may assist in optimizing engine performance by utilizing the OBD2 protocol to communicate with the vehicle's ECU. After approximately 200 kilometers of driving, the device adapts to the driver's habits and may help improve engine efficiency and reduce unnecessary power loss. The NitroOBD2 is available in two versions: Diesel (blue and red) and Gasoline (green and yellow). Key functions include support for reduced fuel consumption and lower emissions. Installation and calibration: 1. Insert the car key into the ignition. 2. Locate the vehicle’s OBD2 port and plug in the NitroOBD2 device. 3. Turn the key to the accessory position (do not start the engine). 4. Press and hold the reset button on the device for about 5 seconds. After releasing, wait 30 to 54 seconds for the device to establish communication with the ECU. 5. Start the engine. 6. The device will begin to recognize the vehicle and driving patterns. After approximately 200 km (or 150 miles), it will complete its adaptation process to help optimize fuel efficiency. Package includes: 1 x Full Chip Tuning Box 1 x English User Manual
