Bonus: If purchased at the asking price, I m including an OBD adapter. Its been a fantastic unit with great app interface, but I m finally making the jump to full pro-tune and voiding my warranty chase bigger numbers. This allows you to use your OBD port for other things without having unplug the JB4.
