Before testing, I was a little worried about the display of power and torque, but when I drove the car, the data of power and torque displayed perfectly. I got to know iOBD2 on a forum and impressed by its function of 0-400m acceleration test. At that time I thought if the phone connected with OBD by Wi-Fi, the data must have some error. Or can the data be accurate? After test, I found the data display accurately. More information,welcome to our web: www.obd2motor.com,or contact sales Betty's skype:ADKobdtools,to get the best price.
