❓ Frequently Asked Questions
Q What parameters can this gauge display simultaneously?
This multi-function gauge supports up to 18 display parameters, including RPM, Speed, Turbo Boost, Water Temperature, Oil Temperature, Oil Pressure, Voltage, Air-Fuel Ratio, Exhaust Temperature, Mileage, Trip Time, and more.
Q What is the boost pressure measurement range?
The boost range is -15 to +45 PSI, or -1 to +3 BAR, making it suitable for both naturally aspirated and turbocharged/supercharged engines.
Q Does this gauge support both metric and imperial units?
Yes. The gauge supports dual unit display for speed (KM/H or MPH), temperature (°C or °F), and pressure (PSI or BAR), allowing easy switching based on your preference or region.
Q How many cylinders does this gauge support?
The gauge supports 1, 2, 3, 4, 5, 6, and 8 cylinders in a loop configuration, making it compatible with a wide range of gasoline engines.
Q Does it have an alarm or warning feature?
Yes. The gauge includes alarm notifications for Speed, RPM, and Water Temperature. Alerts are displayed via on-screen indicator icons to warn you in real time when values exceed safe thresholds.
Q What is the operating temperature range and does it work in extreme conditions?
The working temperature range is -20°C to +60°C (humidity <80%), and storage temperature is -30°C to +80°C. It is designed to reliably operate in most automotive environments, including cold climates and high-heat engine bays.
