P3 Gauge - Audi A3/S3/RS3 (8V) 2015-2020
Custom built multi-function digital boost gauge and more for the 8V generation (2013-2020) Audi A3, S3, and RS3, including 1.0 TFSI, 1.4 TFSI, 2.0 TFSI, 1.6 TDI, 2.0 TDI, S3 2.0 TFSI, and RS3 2.5 TFSI quattro models.
Product is for the gauge only, which requires retrofitting to your existing vent assembly.
Form and Function
Every P3 Gauge is built just for your car. It fits perfectly - like it was born there.
Stealthy. Stylish. Smart.
In one sleek display you get real-time access to everything that matters - Boost, Engine Temps, Performance Timers, Code Reading/Clearing, and more. All that from the included diagnostics port connection or optional add-on sensors.
It’s easy to install, simple to use, and made to last.
Every unit is built to order, hand-assembled, and developed entirely in-house... not by a huge corporation but by a small team who loves cars as much as you do.
Gauge Modes / Readings
P3 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
- 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 analog 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.
-
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.
Accessories:
- Low Profile OBDII Splitter
- Ethanol Sensor Voltage Adapter
- 80psi Analog Boost Sensor
- Ethanol Content Sensor w/ Harness
- Vacuum Tubing Kit
- 0-150 PSI Pressure Sensor (0-5v)
- Digital Wideband O2 Sensor Kit
- Trim Removal Tools
