Frequently Asked Questions (FAQ)
Q
What parameters can the DO904 race dashboard monitor?
The DO904 can monitor a wide range of parameters including RPM (0–9000), Speed (0–255 KM/H or MPH), Boost (-15~45 PSI), Water Temperature, Oil Temperature, Oil Pressure, Air-Fuel Ratio, Exhaust Gas Temperature, and Voltage — all displayed on a single LCD screen.
Q
Does the DO904 support both metric and imperial units?
Yes. You can switch between metric and imperial units using the SET UNIT function at the bottom of the display. This allows you to select your preferred measurement unit for pressure, temperature, and speed.
Q
How does the alarm system work on this gauge dashboard?
The alarm system monitors RPM and Speed values. When a set threshold is exceeded, it triggers both audible alerts (buzzer) and visual warnings through 8 built-in LED indicator lights, ensuring the driver is immediately notified of critical readings.
Q
Can I adjust the screen brightness of the DO904 display?
Yes. The DO904 offers both manual and automatic brightness adjustment. Manual mode provides three brightness levels, while the automatic mode detects ambient light conditions and adjusts sensitivity accordingly — ideal for both daytime and night driving.
Q
What sensors and connectors are included with the wire harness kit?
The wire harness kit includes connectors for Power, Boost Sensor, Oil Pressure Sensor, Air Fuel Ratio Sensor, Oil Temp Sensor, Water Temp Sensor, Exhaust Gas Temp Sensor, RPM (green wire), Speed Meter (red wire), and three spare sockets for future expansion.
Q
What warranty is provided for the DO904?
We offer a one-year warranty on the DO904, covering manufacturing defects. Please note that damage caused by human factors or improper installation is not covered. All warranty claims must be accompanied by proof of professional installation.
