For Subaru WRX STI enthusiasts, monitoring your vehicle’s performance metrics is paramount. While OBD2 gauges are a popular choice, they aren’t always the definitive solution for every parameter you might want to track. If you’re seeking a more direct and potentially more accurate way to keep tabs on critical engine data, especially for parameters beyond the standard OBD2 outputs, the P3 Analog Gauge presents a compelling alternative.
Why Consider an Analog Gauge for Your WRX STI?
OBD2 ports offer a wealth of information, but they have limitations. Certain sensors and readings might not be readily available or updated as quickly as needed for high-performance monitoring. This is where analog gauges shine. By directly connecting to sensors, analog gauges can provide real-time data with potentially higher precision and access parameters that might be inaccessible via OBD2.
The P3 Analog Gauge is engineered to bridge this gap, offering a blend of digital display convenience with the direct sensor readings of traditional analog gauges. It’s designed to integrate seamlessly into your Subaru WRX STI’s interior, providing critical data without cluttering your dashboard with bulky, aftermarket-looking pods.
Key Features of the P3 Analog Gauge
This gauge isn’t just about aesthetics; it’s packed with features designed for serious performance monitoring:
Versatile Analog Readouts
The core strength of the P3 Analog Gauge lies in its four available analog readouts:
-
Analog Boost: Dedicated connection for precise boost pressure readings directly from a sensor in your engine bay. (Boost sensor included, boost tap not included) This direct measurement can be more responsive and accurate than relying solely on OBD2 derived boost estimates.
-
Analog Input 1 & 2: These universal inputs allow you to connect to virtually any 0-5 volt linear output sensor. Think of parameters like:
- Oil Pressure
- Fuel Pressure
- Wideband Air/Fuel Ratio
- Exhaust Gas Temperature (EGT)
- Coolant Temperature (for enhanced accuracy or secondary readings)
This flexibility makes the P3 Analog Gauge incredibly adaptable to your specific monitoring needs, far beyond the limitations of standard OBD2 parameters.
-
Battery Voltage: Essential for diagnosing charging system issues and ensuring your electrical system is healthy. Monitored directly through the power and ground wires.
Optional Auto-Dim Feature
For comfortable nighttime driving, the gauge includes an optional auto-dim feature. By connecting a wire to your headlight circuit, the display intelligently dims when your headlights are activated, preventing glare and maintaining optimal visibility.
Comprehensive Base Kit
The P3 Analog Gauge base kit provides everything you need for installation:
- Integrated Display: Sleek and bright display for easy readability.
- Analog Box Control Unit: The brains of the gauge, processing sensor data.
- Main Harness & Hard-wire Harness: Complete wiring for power, ground, and sensor connections.
- Analog Boost Sensor: High-quality sensor for accurate boost readings.
- Boost Tubing & Connectors: Essential hardware for connecting the boost sensor.
- Wiring Accessories: Zip ties and scotchlok wire taps for a clean and secure installation.
OEM Vent Integration Option
For the ultimate in factory-look integration, P3 Gauges offers an OEM Vent Option. The display is pre-installed in a genuine OEM vent for your Subaru WRX STI, making installation even simpler and ensuring a seamless blend with your interior.
Beyond OBD2: Enhanced Monitoring for the WRX STI
The P3 Analog Gauge is more than just another gauge; it’s a strategic upgrade for WRX STI owners who demand comprehensive and accurate performance data. While OBD2 gauges serve a purpose, the P3 Analog Gauge excels by offering:
- Direct Sensor Accuracy: Analog inputs provide potentially more precise and real-time data compared to OBD2 derived readings.
- Expanded Parameter Monitoring: Track critical parameters beyond the typical OBD2 limitations, like oil pressure or wideband AFR, crucial for tuned or high-performance WRX STIs.
- Clean and Integrated Installation: Maintain a factory-like interior aesthetic while adding powerful monitoring capabilities, especially with the OEM vent option.
- Robust and Reliable Performance: Torture-tested electronics ensure reliable operation even in extreme in-car temperatures.
Ready to Elevate Your WRX STI Monitoring?
If you’re looking for the best way to monitor your Subaru WRX STI’s vital signs, especially parameters beyond the scope of standard OBD2 gauges, the P3 Analog Gauge is a top contender. Its blend of analog precision, digital display technology, and seamless integration makes it an ideal choice for enthusiasts and performance-minded drivers.
