Ultimate Vehicle Monitoring Tool for BMW: Ultra Gauge with 78 Displayable Gauges and Customizable Alarms

Plug-and-play OBD2 live data display for BMW drivers who want real insight on the road and at the circuit

Stop guessing what your engine is doing. This compact digital multi-gauge plugs into your BMW’s OBDII port and streams real-time information to a crisp display, giving you confidence during spirited driving and track days. Many baby M models do not show oil temperature as standard; this unit lets you see it instantly, along with a huge range of other parameters, so you can push hard and protect your investment.

We run this on our own cars and our customers love it for its clarity, reliability and sheer depth of information. It is a must-have upgrade for anyone who cares about engine health, performance data and diagnostics in one tidy package.
