Show original supplier description
The P3 V3 OBD2 Multi-Gauge is custom-built for the first-generation Subaru BRZ, Toyota FT86/86, and Scion FR-S (2013-2021). This digital gauge integrates seamlessly into your vehicle's interior, offering real-time access to vital information such as boost pressure, engine temperatures, performance timers, and the ability to read and clear diagnostic trouble codes. It connects directly through the OBD2 port, with an option for a hardwire kit or OBD2 splitter to keep the port free for other devices. Designed for both form and function, the P3 Gauge is built to last and hand-assembled in-house. The gauge can display readings in both English and Metric units, including PSI/inHg, BAR, Celsius, Fahrenheit, MPH, and KPH. While most functions are accessible via the ECU, optional analog sensors are available for aftermarket forced induction kits (turbochargers, superchargers) or to monitor data not provided by the ECU, such as ethanol content or specific pressure readings. Installation is straightforward, typically taking between 5 to 30 minutes depending on the user's skill level. The P3 Gauge is backed by a lifetime warranty and a 30-day satisfaction guarantee, reinforcing the company's commitment to quality and customer support. It is important to note that while standard modifications and ECU reflashes generally do not affect the gauge's accuracy, piggy-back tuning that alters sensor data may require an optional analog sensor. Additionally, the factory MAP sensor has limitations, and for turbo or supercharged vehicles, an optional analog sensor is recommended for accurate boost readings beyond 5 PSI.
