All-in-One OBD2 Gauge and Scanner

The LUOM KW206 combines a 3.5in digital LCD trip computer with a full OBDII code reader. It works on all 1996 and newer gasoline and diesel vehicles, displaying real-time parameters directly from the vehicle ECU. The unit mounts on the dashboard to keep critical data in the driver's line of sight.

34 Real-Time Parameters with Acceleration Testing

The gauge displays up to 34 data sets including RPM, speed, coolant temperature, fuel consumption, and oxygen sensor readings. It supports 0-100 km/h acceleration timing and allows switching between metric and imperial units per parameter. Coverage ends at non-OBDII vehicles or proprietary manufacturer data streams not in the standard protocol.

One-Click Readiness Key and Custom Alarms

A patented One-Click Readiness Key provides instant emissions monitor status for state inspections. Four user-definable alarms cover RPM, speed, coolant temperature, and voltage with visual alerts. The interface handles code reading, clearing, and live text data streams without requiring a separate smartphone app or laptop connection.
