ScanGauge SG2 Ultra-Compact OBD2 Trip Computer — Real-Time Fuel Economy & Diagnostic Scanner

The ScanGauge SG2 is an ultra-compact OBD2 trip computer that combines a diagnostic scanner, customizable real-time digital gauges, and a fuel-economy monitor in one plug-and-play device.

The SG2 gives drivers quick access to engine data and fuel metrics without complicated installation or extra sensors. Designed for 1996-or-newer OBD2 vehicles — including gas, diesel, propane and hybrid systems — it connects directly to the vehicle’s 16-pin diagnostic port and displays up to four live readouts at once. With programmable gauges, DTC reading/clearing, and 63 backlit color choices, the SG2 is built for drivers who want better fuel insight, on-the-road diagnostics, and a compact display that fits neatly under the dash.

How does the SG2 help me monitor fuel economy while driving?

The SG2 reports real-time fuel consumption and cost-per-mile so you can see exactly how driving habits affect efficiency. It converts sensor data into easy-to-read numbers and updates continuously, letting you adjust throttle, speed, or routes for improved economy.

• Real-time mpg and liters/100 km readouts for immediate feedback
• Cost-per-mile calculation using your fuel price input
• Up to four live gauges shown at once for side-by-side comparison
• High-contrast backlit display readable in varied light conditions

Can the SG2 diagnose and clear check-engine problems?

Yes — the SG2 functions as a basic diagnostic tool that reads Diagnostic Trouble Codes (DTCs) and clears them when needed. It’s useful for identifying faults and turning off the check-engine light during troubleshooting or after repairs.

• Reads standard OBD2 trouble codes and displays code text
• Clears codes and resets check-engine light when appropriate
• Works across a wide range of modern OBD2 vehicles
• No separate scanner or software required — single connection operation

What customization and display options are available?

The SG2 offers flexible gauge programming and display adjustments so you can tailor readouts to your driving needs. Choose from dozens of data points and change color and brightness to suit day or night driving.

• Up to 37 available digital gauges depending on vehicle sensors
• Expandable Add-A-Gauge technology to monitor additional parameters
• 63 backlit color options and adjustable brightness levels
• Shows four gauges simultaneously; programmable layouts for quick access

How easy is installation and daily use?

Installation is plug-and-play: the SG2 requires no batteries and draws power directly from the OBD2 port. Its five-button interface makes navigation and configuration fast, keeping interaction simple while you’re on the go.

• Single plug connection to the vehicle’s 16-pin OBD2 connector
• No additional wiring, sensors, or batteries to install
• Five-button control for quick setup and in-drive changes
• Compact footprint fits discreetly under the dash or on the console

Who is this for: The ScanGauge SG2 is ideal for drivers who want clearer insight into fuel usage and engine status without bulky equipment. It suits fleet drivers tracking cost-per-mile, performance enthusiasts monitoring engine parameters, and everyday motorists seeking to improve fuel efficiency or perform basic diagnostics. If you need compact, reliable, and versatile OBD2 readouts that are easy to set up and customize, the SG2 delivers a practical, on-board solution.
