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 analog inputs or even run in "analog 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 shiftlight)
  • EGT (Exhaust Gas Temp)
  • Battery Volts
  • Acceration 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 analog inputs on the P3 Gauge allow you to use up 3 extra sensors to read data. In addition, it also provides a 4th inpout for auto-dimming display capability.

  • Analog Boost Input
    Use the P3 Analog 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 analog 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.
