Frequently Asked Questions
QWhy does the pointer not return to zero when the gauges are off?
These gauges use stepper motors. The pointer returns to zero only when the gauge is powered on. It is completely normal for the needle to remain in its last position when the power is off — this is not a defect.
QDoes the Air Fuel Ratio Gauge come with an oxygen sensor?
No, the Air Fuel Ratio Gauge does not include an oxygen sensor. You need to use a narrow-band oxygen sensor with an output voltage of 0~1V, which must be purchased separately and installed in your exhaust system.
QWhat thread size is the EGT sensor for the Exhaust Temperature Gauge?
The included EGT (Exhaust Gas Temperature) sensor uses a 1/8 NPT thread size. Please ensure your exhaust pipe or bung has a compatible 1/8 NPT fitting before installation.
QWhat sensor thread size do the Water Temp and Oil Temp gauges use?
Both the Water Temperature Gauge and the Oil Temperature Gauge include a sensor with a 1/8 ZG (BSP) thread. Make sure your engine has or can be fitted with an appropriate 1/8 ZG adapter port for installation.
QWhat is included in the Boost Gauge package?
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 a complete installation on most turbocharged or supercharged vehicles.
QWhat is the voltage range supported by the Voltmeter gauge?
The Voltmeter gauge supports a measurement range of 8V to 18V, making it suitable for monitoring standard 12V automotive electrical systems. It can help detect charging issues or battery health in real time.
