🔬 Wide Band Oxygen Version Descriptions
-
Auto Detection: When the monitor is turned on, it will automatically communicate with the DPU. Once a wide band oxygen signal is detected, the screen will automatically display the Wide Band Oxygen Version; if no wide band oxygen signal is detected, it switches to the Narrow Band Oxygen Version.
Wide Band Mode: The "air-fuel ratio" parameter displays data detected by the wide oxygen sensor, with a range of 0.0~99.9:1. Two additional parameters appear in the multi-function display area: LAMBDA (λ) and OXYGEN (oxygen content percentage).
Narrow Band Mode: When no wide band oxygen signal is detected, the air-fuel ratio parameter shows narrow band sensor data, with a range of 20~10:1.
-
Error Monitoring: While the wide oxygen sensor is working, the controller monitors its status at all times. Once an error is found, the controller stops monitoring the wide oxygen sensor and displays the error code "ERR xx" in the multi-function display area at the bottom of the screen.
("xx" represents the specific error code. For example, when working normally, unplugging the sensor wiring will cause the instrument to display "Err 7F")
⏱ Pre-Heating Notice: When the wide oxygen sensor starts working, there is a pre-heating process of approximately 1–2 minutes. During this time, the air-fuel ratio on the screen will display 0.00, which is a normal display. Once the sensor enters normal operating state, the correct air-fuel ratio value will be shown.

FAQ Frequently Asked Questions
Q What parameters can the DO926WB racing dash panel monitor?
A The DO926WB monitors 9 key parameters: RPM, Speed, Turbo/Boost, Water Temperature, Oil Temperature, Oil Pressure, Voltage, Air-Fuel Ratio, and Exhaust Temperature. It also features a built-in 24H clock.
Q How does the wide band oxygen sensor differ from the narrow band version on this gauge?
A The wide band version provides a precise air-fuel ratio range of 0.0~99.9:1 and also displays LAMBDA (λ) and OXYGEN percentage. The narrow band version only shows a range of 20~10:1. The gauge automatically detects which sensor is connected and switches modes accordingly.
Q What does it mean when the air-fuel ratio displays "0.00" after startup?
A This is completely normal. The wide band oxygen sensor requires a pre-heating period of approximately 1–2 minutes before it can provide accurate readings. Once the sensor is fully warmed up, the correct air-fuel ratio value will appear automatically.
Q What alarm functions are available on the DO926WB?
A The gauge supports audible and visual alarms for Speed, RPM (TACHO), Water Temperature, Oil Temperature, Oil Pressure, Boost, and Voltage. Alerts are triggered through a built-in buzzer and 8 LED indicator lights.
Q Can I customize the display color and brightness of the gauge?
A Yes. The DO926WB offers seven backlight color options in addition to the default white. Brightness can be adjusted manually across three levels or set to automatic mode, which adapts to ambient lighting conditions.
Q What is included in the package and what is the warranty policy?
A The package includes 15 items: Display Monitor, DPU, sensor wires, oil pressure sensor, exhaust temperature sensor, boost pipe and sensor, water/oil temperature sensor, wide band oxygen sensor and wiring, boost pipe air filter, T-fitting, DPU installation panel, and installation screws. A one-year warranty is provided, excluding damage caused by human factors, and proof of professional installation is required for all warranty claims.
