MRCARTOOL M90 Slope Meter Introduction:

Gasoline and diesel vehicles that comply with the standard OBD-II protocol. M90 OBD automotive off-road slope meter is a compact and powerful gauge. It is especially suitable for off-road vehicles that are not equipped with a slope meter.

Additionally, this gauge is appropriate for cars without a speedometer, engine temperature gauge, oil temperature gauge, turbo air intake pressure gauge, and fuel consumption display as well. The M90 off-road gauge is also able to display and monitor the vehicle battery voltage, generator charging voltage, vehicle over speed alarm, high engine temperature and others. In addition, it is possible to read real-time vehicle data streams, scan for engine fault codes and provide and clear of fault codes.

M90 is a multifunctional instrument that works with dual modules.
