Specifications

Many cars provide only minimal information on the instrument cluster. Drivers often cannot see useful engine parameters such as coolant temperature trends, voltage fluctuations or performance metrics unless a diagnostic scanner is connected.

The TecUpdater Smart Gauge acts as a secondary digital dashboard display, providing continuous visibility of important vehicle information while driving.

Instead of relying on occasional diagnostic scans, drivers can now monitor engine health and driving performance directly from the dashboard.

This makes the device particularly useful for:

• Cars with limited instrument cluster data
• Older vehicles without digital dashboards
• Enthusiasts monitoring engine behaviour
• Drivers who want better awareness of vehicle performance

DISPLAY AND USER INTERFACE

The Smart Gauge features a high-contrast digital display designed for easy readability during both daytime and night driving.

Display features include:

• Multiple customizable screen layouts
• Clear graphical representation of vehicle data
• Automatic brightness adjustment
• Compact display suitable for dashboard or windshield mounting

The layout focuses on essential driving parameters so drivers can quickly read key information without distraction.

OBD DATA MONITORING

When connected to the vehicle’s OBD-II port, the display reads real-time ECU data.

Parameters displayed may include:

• Vehicle speed
• Engine RPM
• Coolant temperature
• Battery voltage
• Fuel consumption data
• Turbo boost pressure (when supported by ECU)
• Engine fault codes

This provides deeper visibility into engine performance than a standard dashboard.

GPS DATA MODE

The device also operates in GPS mode, which functions independently of ECU data.

GPS mode provides:

• GPS-based speed measurement
• Digital compass direction
• Altitude information
• Satellite signal strength
• Local time display

This ensures the device remains functional even in vehicles where certain ECU parameters are unavailable.

PROXIMITY GESTURE CONTROL (A520 MODEL)

The A520 variant includes a proximity gesture sensor that allows drivers to switch display pages without pressing physical buttons.

A hand or finger waved near the top edge of the screen changes the display view or acknowledges alerts.

Important clarification:

• Gesture detection works only when the hand is very close to the display
• It is short-range proximity sensing, not long-distance gesture control
• A quick hand wave switches display modes instantly

This allows quick interaction while keeping the driver’s attention on the road.

PERFORMANCE MONITORING FEATURES

The Smart Gauge includes performance monitoring tools for drivers interested in tracking driving performance.

Available measurements include:

• 0–100 km/h acceleration timing
• Braking distance measurement
• Trip distance tracking
• Driving time monitoring

These functions are intended for informational comparison rather than professional testing.

SAFETY ALERTS

The device includes configurable warnings designed to improve driving awareness.

Available alerts include:

• Overspeed alert
• High coolant temperature warning
• High or low battery voltage alert
• Fatigue driving reminder
• Engine fault code notification

These alerts provide early warning signs of potential vehicle issues.

INSTALLATION

Installation is simple and does not require vehicle modification.

Steps:

1. Locate the OBD-II port below the dashboard

2. Connect the supplied OBD cable

3. Mount the display on the dashboard or windshield

4. Start the vehicle

The display powers on automatically when the ignition is switched on.

No wiring cuts, ECU coding or dashboard modifications are required.
