WiFi Upgrade Functionality
WiFi upgrade functionality is a core feature of the DO928. It is primarily used in the following scenarios:
- Fixing vulnerabilities discovered during customer use;
- Providing customized features and user interfaces.
Customer devices do not need to be returned to the factory; they can be upgraded directly to the latest version via WiFi.
⚠ Important Notes:
WiFi upgrades are performed only when customers report malfunctions or request feature updates. Customers must provide the instrument serial number (SN). We do not automatically push updates when internal software is updated.
The instrument serial number is required to execute updates. The update program can only run after we upload the update file to the server. Running the update program directly on the instrument will result in failure, as the program cannot execute the update.

Frequently Asked Questions (FAQ)
Q What parameters can the DO928 monitor simultaneously?
The DO928 is a 9-in-1 racing gauge that can monitor RPM, Speed, Oil Pressure, Oil Temperature, Water Temperature, Boost, Air-Fuel Ratio, EGT (Exhaust Gas Temperature), and Voltage — all at the same time on a single display.
Q How does the WiFi upgrade feature work?
The WiFi upgrade feature allows your device to receive firmware updates wirelessly without returning it to the factory. Upgrades are only performed when you report a malfunction or request a feature update. You must provide your instrument's serial number (SN), and the update file must be uploaded to the server by us before it can be applied.
Q Can I run the WiFi update program directly on the instrument without contacting support?
No. Running the update program directly on the instrument without our server-side preparation will result in failure. The update can only be executed after we upload the update file to the server using your provided serial number (SN). Please contact our support team first.
Q Which parameters support alarm settings on the DO928?
The DO928 supports alarm configuration for all 9 monitored parameters: Speed, RPM, Boost, Water Temperature, Oil Temperature, Oil Pressure, Voltage, Air-Fuel Ratio, and Exhaust Temperature. You can set threshold alerts to be notified when any value exceeds your defined range.
Q What is the warranty policy for the DO928?
The DO928 comes with a one-year warranty. The warranty does not cover damage caused by human factors such as improper use or installation. All warranty claims require proof of professional installation. Please ensure installation is performed by a qualified technician.
Q Does the DO928 support both metric and imperial units?
Yes. The DO928 supports both metric and imperial units across multiple parameters. For example, Speed can be displayed in KM/H or MPH, Temperature in °C or °F, and Pressure in PSI or BAR — giving you full flexibility based on your regional preference.
