Looking to keep a closer eye on your Toyota GR86 or Subaru BRZ’s vital stats without a complicated gauge install? I recently explored options for monitoring coolant, oil temps, and boost levels for track days and stumbled upon the P3 V3 Obd2 Meter. Having seen it pop up in a GR86 Facebook group, I decided to give the digital gauge a try, opting for the base unit without additional sensors for now, as forced induction isn’t in my immediate plans. Based in the same state, P3 Gauges shipped it out the very same day, and it arrived lightning fast the next day.
The installation of this OBD2 meter was unbelievably straightforward. Armed with just a Phillips head screwdriver borrowed from a colleague, the whole process was done in about 15 minutes. The gauge integrates seamlessly into the existing air vent, maintaining airflow and keeping the display low-profile. It doesn’t obstruct your view through the windshield like pillar-mounted gauges, which is a big plus. For anyone wanting a clean and functional data display, this is definitely worth considering.
This P3 V3 OBD2 meter pulls a wealth of data directly from your car’s OBD2 port, including:
- Boost Pressure: Monitors boost levels using OEM sensors (or with an optional P3 analog boost sensor for custom setups).
- Engine Oil Temperature: Crucial for tracking engine health, especially during spirited driving or track sessions.
- Coolant Temperature: Essential for preventing overheating and ensuring optimal engine performance.
- Air/Fuel Ratio: Displays in AFR or Lambda, allowing you to monitor engine fueling for efficiency and performance.
- Vehicle Speed: Digitally accurate speed readout, with calibration adjustments from -9% to +20%.
- Intake Air Temperature: Important for understanding engine performance in varying ambient conditions.
- Throttle Angle: Shows real-time throttle input, useful for diagnosing response and control.
- Ignition Timing: Provides insight into engine timing advance and potential issues.
- Engine RPM: Standard tachometer function for engine speed monitoring.
- Exhaust Gas Temperature (EGT): Valuable for monitoring turbocharger health and combustion efficiency (sensor dependent).
- Battery Voltage: Keeps tabs on your car’s electrical system health.
- Programmable Shift Light: Customizable visual aid for perfect gear changes.
- Dual Analog Inputs: Two 0-5 volt linear inputs (brown and blue wires) for adding external sensors like wideband O2 or pressure sensors.
- Performance Timers: Built-in timers for acceleration (0-60mph, 0-100mph, 60-130mph) and braking (60-0mph, 100-0mph) tests.
For GR86 and BRZ owners seeking a simple, effective, and integrated OBD2 meter solution, the P3 V3 OBD2 Gauge is a fantastic option. It delivers a wealth of real-time data in a clean, easy-to-install package.
