SAAS Digital Multi Function OBD2 Real Time ECU Monitor - SDM1040

The SAAS SDM1040 compact OLED OBD2+ gauge is a powerful yet unobtrusive way to keep vital vehicle data in clear view. Designed for modern vehicles using the OBDII CAN-BUS standard, it connects directly to the vehicle’s ECU to display real-time operating information without the need for additional sensors or complex wiring.

Easy to install

Its slim form factor and versatile mounting design make it suitable for both left-hand and right-hand installations, allowing a clean, factory-style fit in a wide range of cabins. Once installed, the gauge provides instant access to key engine and vehicle parameters, helping drivers monitor performance, efficiency, and potential issues at a glance.

Customise and set alerts

Customisable alerts add an extra layer of protection, with visual and audible warnings available for multiple monitored values. Display preferences can be tailored to suit regional and personal requirements, including selectable pressure and temperature units, while adjustable ambient lighting ensures excellent visibility day or night.

OBD2 Scan Tool

The gauge also supports fault code reading and clearing, making it a practical diagnostic companion for daily driving, touring, or performance applications. All settings are retained when the vehicle is powered off, so your configuration remains exactly as you left it.

Data availability depends on the vehicle’s ECU and the parameters it broadcasts via OBDII; not all vehicles will support every data channel.
