For car enthusiasts and performance drivers, keeping a close eye on vehicle parameters is crucial. When I was looking for a way to monitor coolant temperature, oil temperature, and eventually boost levels for track days in my GR86, I discovered the P3 V3 OBD2 gauge. While custom gauge pods are still emerging for this platform, this digital gauge kit caught my attention through a recommendation in an online GR86 community. I opted for the standalone digital gauge initially, as forced induction isn’t on my immediate modification list, negating the need for a boost tap for now. Impressively, the gauge shipped the same day I ordered it and arrived the next day, thanks to P3 Gauges being located in my state.
The installation process was surprisingly straightforward. Armed with just a Phillips screwdriver borrowed from a colleague, I had the gauge up and running in under 15 minutes. Its discreet integration into the existing air vent is a major plus – airflow isn’t significantly impeded, and it avoids obstructing the windshield, unlike pillar-mounted gauges. This OBD2 gauge is definitely a worthwhile addition for anyone wanting to monitor their vehicle’s vital signs. It conveniently pulls a wealth of data directly from the OBD2 port, including:
- Boost Monitoring: (Utilizes OEM sensors via OBD2 or optional P3 analog boost sensor)
- Engine Oil Temperature: Essential for performance and longevity.
- Coolant Temperature: Critical for preventing overheating.
- Air/Fuel Ratio: Displayed in AFR or Lambda for tuning insights.
- Vehicle Speed: Calibratable for accuracy with aftermarket modifications (-9% to +20% adjustment range).
- Intake Air Temperature: Important for understanding engine performance in varying conditions.
- Throttle Angle: Real-time throttle position monitoring.
- Ignition Timing: Key data point for engine tuning and diagnostics.
- Engine RPM: Standard tachometer function.
- Exhaust Gas Temperature: Valuable for monitoring catalytic converter health and engine conditions.
- Battery Voltage: Keeps an eye on the electrical system.
- Programmable Shift Light: Customizable visual aid for optimal gear changes.
- Dual Analog Inputs: Two 0-5 volt linear inputs for adding aftermarket sensors (brown and blue wires).
- Performance Timers: Built-in timers for acceleration (0-60mph, 0-100mph, 60-130mph) and braking (60-0mph, 100-0mph).
