No bro i never used any type of obd2 scanning tool myself,i have searched and also heard that,these cheap obd2 scanners do nothing,as they can't read and erase any type of trouble codes in vehicle,even these cheap obd scanners don't have ability to read and detect full functions of ecu and sensor's readings...it is better to search for good efi scanning expert in your town,so that he can do scanning properly by expensiv,precised and effective scanning tool,and solve any issue that could be in your vehicle.
