OBD Diagnostic and Boost Guages

Want a boost gauge without the hassle of wiring? These plug directly into your OBD port, allowing you to customize the device to your preferences. If you have a Mazdaspeed 3 with a TV screen, it fits seamlessly, making it stealthy. You can monitor any data output by the ECU, including fuel trims, intake temperatures, timing, fuel economy, tachometer, coolant temperature, and EGR activation. Being OBD2 compatible, it works with many different cars.”
