Frequently Asked Questions (FAQ)
Q Why doesn't the pointer return to zero when the gauge is off?
A These gauges use stepper motors. They require power to return to the zero position. It is completely normal for the pointer not to return to zero when the vehicle is turned off.
Q Are these gauges compatible with diesel vehicles?
A These gauges are designed for 12 volt gasoline vehicles. They are not recommended for diesel vehicles unless otherwise specified.
Q Does the Air Fuel Ratio Gauge come with an oxygen sensor?
A No, the Air Fuel Ratio Gauge does not include an oxygen sensor. It requires a narrow band oxygen sensor with an output voltage of 0~1V, which must be purchased separately.
Q What thread size does the EGT sensor use?
A The EGT (Exhaust Temperature Gauge) sensor uses a 1/8 NPT thread size, which is a standard fitting widely available in automotive applications.
Q What is included in the Boost Gauge package?
A The Boost Gauge package includes: 1 × Boost Gauge, 1 × Boost Sensor, 1 × PVC Hose (6 Feet), 1 × T-Fitting, 1 × Wire, and 1 × English Manual. Everything you need for installation is included.
Q What is the voltage range supported by the Voltmeter gauge?
A The Voltmeter gauge supports a measurement range of 8~18V, making it suitable for standard 12V automotive electrical systems and monitoring battery or charging system health.
