The Details

We designed the P3 Gauge to read the most important data from your specific vehicle for easy plug and play install. You'll get everything you need with a single OBD port connection to be up and running in minutes. If you wish to add additional sensors, or not use OBD at all, advanced tuners can use analogue inputs or even run in "analogue only" mode.

OBD Port Data (CANbus input):

Boost Pressure
Coolant Temp
Air/Fuel Ratio (AFR or Lambda)
Vehicle Speed (Calibrated or Raw)
Intake Air Temp
Throttle Angle
Ignition Timing
Engine RPM (with shift light)
EGT (Exhaust Gas Temp)
Battery Volts
Acceleration timers (0-60, 0-100, 60-130)
Braking timers (60-0, 100-0)
Read and clear DTC (Trouble Codes)

Optional Analog Inputs:

Optional but powerful. The analogue inputs on the P3 Gauge allow you to use up 3 extra sensors to read data. In addition, it also provides a 4th input for auto-dimming display capability.

Analogue Boost Input
Use the P3 Analogue Boost Sensor to read up to 80psi boost for advanced tuners and cars with aftermarket forced induction kits.
2x Universal 0-5v Inputs
Two individual 0-5volt universal analogue inputs with flexible configuration allows for near infinite possibilities and customization.
Dimmer Voltage Detection Input
Configure the gauge to d.On.A mode and anything over 1 volt tells the gauge to dim, perfect for easy tapping into existing interior lighting.

How hard is it to install a P3 Gauge and how long does it take? Most installs take 5–30 minutes, depending on your skill level and vehicle.
How accurate is the P3 Gauge? It displays real-time data from your ECU. If configured correctly, readings match your vehicle's output. An optional analogue sensor can be added for certain data types to ensure maximum accuracy.
Will modifications or tuning affect my readings? Standard modifications and ECU reflashes typically do not affect accuracy. Only piggy-back tuning that alters sensor data may require the optional analogue sensor.
Can the P3 Gauge display both English and Metric units? Yes. You can configure units to English, Metric, or a mix of both, with selections for PSI/inHg, BAR, Celsius, Fahrenheit, MPH and KPH.
Will installing a P3 Gauge void my vehicle warranty? No. Using a P3 Gauge is the same as plugging in an OBD2 scan tool. Under the Magnuson-Moss Warranty Act (15 U.S.C. § 2301 et seq.) and Right-to-Repair principles, you have the right to use your own diagnostic tools through the OBD2 port. A manufacturer cannot void or deny warranty coverage just because an aftermarket tool or gauge was connected.
Do I need extra parts to install a P3 Gauge? In most vehicles, no additional parts are required. Certain readings that are not provided by the ECU may require our optional analogue sensor kit, depending on the data you want to monitor.
How does the P3 Gauge get data from my cars existing sensors? It plugs into the OBD2 port and acts as a diagnostics reader. If you want to keep that port free, a hard-wire harness kit is available.
Will installing it in the vent affect heating or A/C? The P3 Gauge is engineered to retain airflow through your vent, so heating and A/C performance are not affected. Each gauge is designed for its specific vehicle to ensure vent operation is not compromised.
Can the P3 Gauge handle extreme temperatures? Yes. We have torture-tested our gauges from −94 °F to extreme heat well beyond typical in-car conditions, including scenarios hot enough to soften or melt plastics, and they continued to function without failure.
