❓ Frequently Asked Questions
Q What vehicles is this 4 in 1 gauge compatible with?
This gauge is compatible with 12V gasoline vehicles with 1 to 8 cylinders, making it suitable for a wide range of cars, trucks, and other gasoline-powered vehicles.
Q Why doesn't the pointer return to zero when the vehicle is off?
These gauges use stepper motors that 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 — this does not indicate a defect.
Q What should I do if the needle is shaking or the reading is unstable?
If you experience needle shaking or unstable readings, please take the RPM signal directly from the original tachometer, camshaft, or injection pot. This typically resolves signal interference issues.
Q What sensors are included, and what thread specification do they use?
The package includes an Oil Temperature Sensor, a Water Temperature Sensor, and an Oil Pressure Sensor. All three sensors use the 1/8 ZG thread specification.
Q Is installation difficult? Do I need professional tools or experience?
No, installation is designed to be straightforward. A detailed installation guide and an English user manual are included in the package, making it accessible for DIY enthusiasts without professional automotive experience.
Q What does the shift light feature do?
The built-in shift light alerts you when to shift gears based on your engine's RPM levels. This helps optimize your gear changes for better performance and fuel efficiency while driving.
