P3 Gauge - Seat Leon Mk2

P3 Gauge – SEAT Leon Mk2

Custom built multi-function digital boost gauge and more for the Mk2 (2005-2012) SEAT Leon Reference, Stylance, Sport, FR, and Cupra models.

Form and Function

Every P3 Gauge is built specifically for your vehicle. It fits perfectly—like it was born there.

Stealthy. Stylish. Smart.

In one sleek digital display, you get real-time access to everything that matters, including boost, engine temperatures, performance timers, and diagnostic functions. All data is delivered via the included OBD diagnostic port connection, with optional add-on sensors available for advanced monitoring.

It’s easy to install, simple to use, and made to last.

Each 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

The P3 Gauge is designed to read the most important data from your specific SEAT platform, allowing true plug-and-play installation. With a single OBD port connection, you’ll be up and running in minutes.

For advanced users, the gauge also supports analog inputs and can operate in analog-only mode if OBD data is not required.

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 shift light)

• Exhaust Gas Temperature (EGT)

• Battery Voltage

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

• Braking Timers (60–0, 100–0)

• Read and Clear Diagnostic Trouble Codes (DTCs)

Optional Analog Inputs

Optional but powerful. The analog inputs on the P3 Gauge allow up to three additional sensors for expanded data monitoring. A fourth input is dedicated to automatic display dimming.

Analog Boost Input
Use the optional P3 Analog Boost Sensor to monitor up to 80 PSI—ideal for advanced tuning or vehicles with aftermarket forced-induction systems.

2× Universal 0–5V Inputs
Two independent 0–5V analog inputs provide flexible configuration options, allowing near-limitless customization with 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.
