BluTrax is 100% accurate, guaranteed. All data is transmitted using Bluetooth Technology to a user’s PC instead of using a hardwire. The data is accessed by using the BluTrax device which is plugged into a vehicle’s Engine Control Unit (ECU). A battery is not necessary as BluTrax only requires a small amount of power to operate. BluTrax is designed to work with any make or model built after 1997. BluTrax can be used for personal or commercial use for diagnostic analysis.
