This compact yet powerful device plugs directly into your car’s OBD2 port, transforming your driving experience with real-time data and insightful diagnostics.
Dive Deep into Real-Time Vehicle Data
The P3 OBD2 Multi-Gauge V2 is engineered to deliver a wide array of crucial readouts, providing a comprehensive overview of your vehicle’s operating parameters. Whether you’re monitoring performance on the track or ensuring optimal engine health during your daily commute, this multi-gauge keeps you informed.
Essential Performance Parameters at Your Fingertips
- Boost/Vacuum: Accurately monitor your engine’s boost pressure, crucial for turbocharged vehicles. The gauge supports readings from the MAP sensor via the OBD2 port, optional analog boost sensors, and even T-MAP sensor wire tapping for certain BMW models. Displaying in PSI, inHg, or BAR, it caters to your preferred unit.
- Coolant Temperature: Go beyond the vague needle on your dashboard and get precise coolant temperature readings. Displayed in Celsius or Fahrenheit, this readout is vital for preventing overheating and ensuring optimal engine temperature.
- Intake Air Temperature: Understand the temperature of the air entering your engine. Displayed in Celsius or Fahrenheit, knowing your intake air temperature is crucial for assessing engine performance and identifying potential issues related to air intake.
- Ignition Timing: Gain insights into your engine’s ignition timing, measured in degrees relative to Top Dead Center (TDC). This readout is essential for performance tuning and diagnosing potential timing-related problems.
- Exhaust Gas Temperature (EGT): Monitor the temperature of exhaust gases exiting your engine. Displayed in Celsius or Fahrenheit, EGT readings are critical for preventing damage to catalytic converters and turbochargers, especially under high-performance driving conditions.
- Throttle Position: See exactly how open your throttle plate is, displayed as a percentage or in degrees depending on your vehicle. This is useful for understanding engine response and diagnosing throttle-related issues.
- Engine Speed (RPM) with Shift Light: Track your engine speed in rotations per minute. The integrated programmable shift light adds a performance edge, allowing you to optimize gear changes.
- Unadjusted Vehicle Speed: Access the raw, unadjusted vehicle speed directly from the ECU. Understand the true speed your vehicle is traveling, which may differ slightly from your speedometer due to factory adjustments. Displayed in MPH or Km/h.
- 0-60 MPH (or 0-100 Km/h) Timer: Automatically measure your vehicle’s acceleration from 0 to 60 MPH (or 0 to 100 Km/h). This built-in timer provides quantifiable performance metrics for acceleration runs.
- Battery Voltage: Keep a close eye on your battery and alternator performance with real-time voltage readings. This is crucial for preventing electrical issues and ensuring reliable vehicle operation.
Enhanced Performance Metrics with Optional Track Pack Upgrade
Unlock even more advanced monitoring capabilities with the optional Track Pack software upgrade. This enhancement expands the P3 OBD2 Multi-Gauge V2’s functionality, providing data crucial for serious performance enthusiasts:
- Air/Fuel Ratio (AFR): Accurately monitor your engine’s air-fuel mixture. Displayed as XX.XX parts air to 1 part fuel, AFR readings are essential for optimizing engine performance and preventing engine damage from running too lean or too rich.
- 0-100 MPH (or 0-160 Km/h) Timer: Extend your acceleration measurement to 0-100 MPH (or 0-160 Km/h), providing a broader picture of your vehicle’s acceleration capabilities.
- 60-130 MPH (or 100-210 Km/h) Timer: Measure high-speed acceleration from 60-130 MPH (or 100-210 Km/h), a critical metric for evaluating performance at higher speeds.
- 60-0 MPH (or 100-0 Km/h) Braking Timer: Quantify your vehicle’s braking performance by measuring the time it takes to decelerate from 60-0 MPH (or 100-0 Km/h).
- 100-0 MPH (or 160-0 Km/h) Braking Timer: Further assess braking performance from higher speeds with the 100-0 MPH (or 160-0 Km/h) braking timer.
Peak Performance Analysis: Recall, Record, and Playback
The P3 OBD2 Multi-Gauge V2 goes beyond real-time monitoring with advanced features for performance analysis:
- Peak Recall: Quickly recall the peak value reached for any monitored parameter since the last reset or vehicle start. For 2008+ models, it intelligently stores peak values for EGT, Air, and Coolant in the background, allowing you to review maximum temperatures even after focusing on other readouts during a drive or track session. A simple tap of the left button instantly displays peak values.
- Record/Playback (CAN-bus Vehicles): For vehicles with CAN-bus systems, the gauge offers a 15-second record and playback feature. Capture 15 seconds of historical data from the current mode by pressing the peak recall button during a performance run. Review this recorded data, including RPM scaled on the bar graph, by holding the peak recall button, enabling detailed post-run analysis.
Integrated Diagnostic Tools: Code Reading and Clearing
The P3 OBD2 Multi-Gauge V2 also integrates essential diagnostic functionalities:
- Automatic Code Reading: For 2008 and newer vehicles, the gauge automatically reads diagnostic trouble codes (DTCs) upon startup, keeping you immediately informed of any potential issues. For pre-2008 vehicles, this feature can be easily enabled in the configuration menu.
- Extended BMW “Dealer Level” Code Reading: For BMW E8X/E9X, 2008+ E6X models, and MINI vehicles, the gauge supports extended “dealer-level” code reading, providing more in-depth diagnostic information.
- Code Clearing: Effortlessly clear stored diagnostic trouble codes directly through the gauge’s configuration menu. By navigating to the “Clr.C” option and holding the left button, you can clear codes after addressing the underlying issues. For some 2014+ vehicles, code clearing may require the ignition to be in the “Key On, Engine Off” (KOEO) position.
The P3 OBD2 Multi-Gauge V2 is more than just a gauge; it’s a comprehensive vehicle monitoring and diagnostic system packed into a single, user-friendly device. Whether you are a performance enthusiast, a weekend racer, or simply a car owner who wants to stay informed about your vehicle’s health, the P3 gauge provides the data and insights you need to drive with confidence and optimize your vehicle’s performance.
