Custom Digital Instrument Clusters

Classic cars deserve real data. Our custom digital instrument cluster displays RPM, speed, coolant temperature, fuel level, oil pressure, battery voltage, and warning indicators - reading from CAN bus or direct sensors - on a clean modern display that fits behind a classic dash or in any enclosure you design. Recent work also includes classic cluster-housing fitment studies and live data-view screen validation.

Development Status: The digital cluster is currently in active development. Hardware design, display firmware, and data-view validation are in progress. We are accepting custom project inquiries - contact us to discuss your cluster requirements and vehicle.

What It Shows

Gauge Channels

All the data your engine produces - visible at a glance.

RPM
Engine Speed

Tachometer from crank signal or CAN.

SPD
Vehicle Speed

VSS or CAN bus wheel speed.

TEMP
Coolant Temp

NTC sensor or CAN message.

FUEL
Fuel Level

Sender resistive or capacitive input.

OIL
Oil Pressure

Analog pressure sender or CAN.

BATT
Battery Voltage

Charging system monitoring.

WARN
Warning Indicators

Check engine, oil, temp, and custom alerts.

CAN
Bus Input

Multiple gauges over a single network.

Design Goals

Built for Classic Car Installations

Dual Input Mode

Works with CAN bus data from a modern ECU or sensor hub - or reads sensors directly. Switch between modes per channel when one signal is still off-bus.

Compact Form Factor

Designed to fit behind a classic instrument panel or in a custom pod. The display board is separate from the processing board so packaging stays flexible.

Configurable Layout

Gauge positions, colors, scale markings, and warning thresholds are configurable per project. The cluster should match the build, not force the build to match the cluster.

Warning Logic

Set high-temp, low-oil-pressure, and low-voltage thresholds. When crossed, the relevant gauge changes color and an indicator activates.

Part of the Module Stack

Designed to work with the Fan Controller Module and Sensor Hub as the display layer of the three-module system. It can also work standalone if you only need gauges.

Night / Day Brightness

Automatic or manual brightness adjustment keeps the display readable in direct sunlight and comfortable during night driving.

Who It's For

Project Types

Classic Car Restomod

Keep the original dash shape but replace the analog gauges with a custom digital cluster. Reads the same data while working with modern electronics.

Engine Swap Builds

When the original cluster has no connection to the new engine, replace it entirely. The cluster reads from the swap ECU CAN output or from new sensors.

Race / Track Builds

A clean panel with the gauges that matter - RPM, temperatures, oil pressure, voltage, and warnings that can be seen instantly.

Project Cars - UAE

UAE market classic cars with modified or swapped engines often have no working gauges at all. A custom cluster restores situational awareness and adds value to the build.
