I had this for a month and its awesome but now that I got the JB4 that connects to the OBDii I can not use both and don't need the scan tool anymore. $100 and free shipping(US only).
Professional Grade Automotive Scan Tool. Dashboard real-time gauges on your phone including a boost guage and clearing codes and check engine lights.
