P3 Gauge - Audi A3/S3/RS3 8P

P3 Gauge – Audi TT / TTS / TTRS 8J

Custom built multi-function digital boost gauge and more for the 8P generation (2003-2013) Audi A3, S3, and RS3, including 1.6, 1.8 TFSI, 2.0 TFSI, 3.2 VR6, 1.6 TDI, 1.9 TDI, 2.0 TDI, S3 2.0 TFSI, and RS3 2.5 TFSI quattro models.

Form & Function

Every P3 Gauge is engineered specifically for your vehicle. It integrates seamlessly into the factory interior—so precise it looks like it came that way from the factory.

Stealthy. Stylish. Smart.

From one sleek digital display, you gain instant access to critical performance and engine data including boost, temperatures, timers, and diagnostics. The gauge connects via the included OBD port for true plug-and-play installation, with optional add-on sensors available for more advanced monitoring.

Each unit is built to order, hand-assembled, and developed entirely in-house by a small team of enthusiasts—not mass-produced by a large corporation.

Gauge Modes & Readings

The P3 Gauge is designed to read the most important data from your specific Audi platform, allowing you to be up and running in minutes using a single OBD connection.

For advanced setups, the gauge also supports analog inputs and can operate in analog-only mode if desired.

OBD Port Data (CANbus Input):

• Boost Pressure

• Coolant Temperature

• Air/Fuel Ratio (AFR or Lambda)

• Vehicle Speed (Calibrated or Raw)

• Intake Air Temperature

• Throttle Angle

• Ignition Timing

• Engine RPM (with programmable shift light)

• Exhaust Gas Temperature (EGT)

• Battery Voltage

• Acceleration Timers (0–60, 0–100, 60–130)

• Braking Timers (60–0, 100–0)

• Read & Clear Diagnostic Trouble Codes (DTCs)

Optional Analog Inputs

Optional but powerful. The analog inputs on the P3 Gauge allow up to three additional sensors, plus a fourth input dedicated to automatic display dimming.

Analog Boost Input
Use the optional P3 Analog Boost Sensor to monitor up to 80 PSI, ideal for high-boost or custom forced-induction applications.

2× Universal 0–5V Inputs
Two configurable 0–5V analog inputs allow near-limitless customization for additional sensors.

Dimmer Voltage Detection Input
Configure the gauge to d.On.A mode—any signal over 1 volt triggers automatic dimming, making it easy to integrate with factory interior lighting.
