Your vehicle determines the readings. Boost, gear, fuel rail, DPF and other data-dependent functions appear only when the required data is available.

THE EVERYDAY ESSENTIALS

Core gauge features.

Shared monitoring, with kit-specific Race options labelled below.

Engine monitoring — Kits 1, 2 and 3
KITS 1, 2 & 3

Engine monitoring

RPM, speed, temperatures and boost.

See all engine readings

RPM · speed · intake-air temperature (IAT) · coolant temperature · boost · engine load · throttle position · mass airflow (MAF / air mass).

Boost needs supported pressure data. Available readings depend on your vehicle.

Electrical — Kits 1, 2 and 3
KITS 1, 2 & 3

Electrical

Voltage, charging and battery information.

See electrical readings

Battery voltage · voltage range · alternator charge · lambda voltage · battery-health screen.

Values depend on the data your vehicle provides.

Fuel information — Kits 1, 2 and 3
KITS 1, 2 & 3

Fuel information

Consumption in L/100 km or L/h, plus fuel-rail pressure where supported.

Last drive report — Kits 1, 2 and 3
KITS 1, 2 & 3

Last drive report

Review the peaks and highlights from your last drive.

What the report contains

Maximum temperatures · top speed · maximum RPM · peak boost · voltage range · new engine codes · drive rating.

Trip information — Kits 1, 2 and 3
KITS 1, 2 & 3

Vehicle information

View the supported vehicle information supplied by your ECU: VIN, ECU type, engine type and communication protocol.

Why some readings or screens do not appear
  • Boost / maximum boost: supported MAP or pressure data is required.
  • Gear: requires a supported gear readout.
  • Fuel rail: requires the appropriate ECU data.
  • DPF: requires supported DPF data and Kit 3 software.
  • Screen angle: appears for round displays.

A supported kit and display do not guarantee that every vehicle supplies every reading.
