Explore our high-end digital dashboard modules and customized sensors engineered for professional track usage, trackday tuning, and industrial vehicular telemetry integration.
Established in 1986, Ruian DongOu Automobile Meter Factory has positioned itself at the cutting edge of global automotive measurement systems research, design, and manufacturing. Across nearly four decades of structural innovation, our technical core has expanded to meet high-precision diagnostic and real-time telemetry challenges in professional racing, customized passenger car modifications, and commercial vehicle applications.
By executing deep vertical integration, from physical sensor calibration to electronic firmware design, we ensure that every display system we release functions with unmatched reliability under extreme track conditions. Our engineering prowess is split across two specialized commercial brands:
Leveraging Ruian's robust automotive components ecosystem, DongOu integrates localized cost efficiencies with advanced global quality testing standards.
Our production lines leverage fully automated high-speed SMT assembly, automated optical inspection (AOI), and multi-stage wave soldering systems to eliminate manual assembly errors in multi-layered PCBs.
Every DO917 display panel and associated sensor kit undergoes intense thermal cycling (from -20°C to +80°C) and rigorous multi-axis vibration testing simulating endurance track loads.
We calibrate our high-precision air-fuel ratio, boost pressure, exhaust gas temp (EGT), and water/oil temperature sensors using physical micro-calibration chambers for linear data output.
We support fully customizable boot screens, localized user interfaces, tailored dial ranges, and private label laser-etched branding for international distribution networks.
In modern performance racing and heavy duty equipment diagnostics, the classic analog gauge system struggles to display complex layered datasets without cluttering the driver’s immediate sightlines. The DO917 Series Racing Dashboard acts as an all-in-one centralized telemetry station. It consolidates raw analog sensor outputs, OBDII data channels, and CAN-bus messages into a single, high-contrast digital interface.
The primary advantage of the DO917 series is its ability to bypass complex auxiliary wiring harnesses by tapping directly into the vehicle's standard Controller Area Network (CAN) bus. By receiving and processing high-frequency data frames, the dashboard displays engine RPM, manifold absolute pressure (MAP), throttle position sensor (TPS) values, and fuel trim updates in milliseconds, reducing latency to virtually zero.
For custom racing chassis or vintage engines lacking a centralized ECU or standard OBDII diagnostic port, the DO917 is supplied with a comprehensive, stand-alone sensor suite. This system directly processes independent inputs:
The display panel uses high-brightness OLED/LCD matrix components featuring adaptive auto-dimming sensors. The anti-glare, polarization-friendly screen guarantees perfect readability even in open-cockpit formula cars under direct midday sunlight. High-visibility progressive shift lights (LED bar) are positioned at the top of the casing, allowing drivers to track RPM ranges using peripheral vision.
Adapting automotive measurement platforms to electrification, cloud-integrated telemetry, and smart diagnostics.
As electric drive systems phase out traditional mechanical parameters like fuel level and oil temperature, modern telemetry systems must display battery cell voltages, state of charge (SoC), thermal battery health, regenerative braking current, and motor inverter RPM. Ruian DongOu is actively adapting the DO917 framework to capture CAN-bus outputs from commercial battery management systems (BMS).
Future iterations of racing telemetry rely on remote tracking. By integrating low-energy Bluetooth (BLE) and integrated Wi-Fi modules, the DO917 allows race mechanics and fleet managers to extract real-time diagnostic parameters, overlay track positions, and export raw logs to cloud analysis platforms via custom smartphone applications.
Rather than simply alerting drivers when thermal thresholds are breached, modern smart dashboards analyze parameter trends. If oil temperature climbs relative to static RPM levels, the integrated firmware triggers early dashboard flashing indicators, allowing the driver to pull over before structural engine failure occurs.
For logistics and heavy commercial machinery operations, tracking engine parameters is critical to extending service life. By deploying standardized dashboard panels, logistics operators secure uniform operator interfaces, streamlining machinery diagnostics and lowering operator training curves across mixed equipment types.
How our specialized digital instruments and sensor kits solve integration bottlenecks across diverse environments.
On race day, mechanical parameters change rapidly. Pit crews require precise metrics regarding oil pressure stability under sustained lateral G-forces. The DO917 dash monitors fluctuations in real time, signaling low pressure thresholds instantly through bright shift light alerts, saving expensive performance engines from lubrication loss.
Tuning heavily boosted turbocharged engines requires precise tracking of the air-fuel ratio (AFR) and exhaust gas temperatures (EGT). Installing individual analog gauges for each parameter results in a complex, messy dashboard layout. Our 10-in-1 OLED and LCD screens combine all key readouts onto a clean, unified panel, streamlining engine tuning and diagnosis.
Offroad utility, construction, and marine vessels require instrumentation that can withstand wet, dusty, and high-vibration conditions. Thanks to heavy-duty sealed casings and military-grade multi-pin connectors, our dashboards resist environmental dust and moisture ingress, maintaining reliable operation in challenging industrial settings.
We support international wholesale networks, local tuning shops, and automotive manufacturers with tailored OEM/ODM sourcing structures.
Our standard production cycle for standard distributor batches runs between 15-25 days. For customized private labels, prototype delivery spans 30-40 days. All shipments originate from major ports (Ningbo/Shanghai), ensuring fast shipping times globally.

Clear, engineering-focused answers regarding compatibility, installation, and procurement procedures.
The DO917 series is highly versatile. It can display vehicle metrics via an OBDII diagnostic link or by connecting directly to the individual sensors (water temp, oil temp, pressure, tachometer wire) included in our custom sensor kits. This allows it to work seamlessly on modern EFI vehicles, vintage carbureted track cars, and custom kit cars alike.
The Bluetooth dashboard system includes an engine bay transmitter module. All the physical sensor leads (EGT, pressure, temperature) run to this unit, which then transmits the data wirelessly to the cockpit display dashboard. This design simplifies installation by eliminating the need to route multiple sensor wires through the vehicle firewall.
For custom brand logo integration on instrument faces or digital boot screens, our standard MOQ starts at 100 units. Smaller sample runs can be negotiated depending on layout complexity and technical specifications.
Yes. Our premium GragonGauge modification lines are built with sealed front bezels and anti-fog lenses. While not designed for continuous submersion, they easily withstand splashes and damp environments, making them ideal for open powerboats, marine consoles, and utility vehicles.
All our sensor connectors feature secure, locking terminal designs that prevent connection loss. The internal components of our digital gauge boards are secured using vibration-dampening silicon compounds. This protects the delicate electronic solder joints from high-frequency vibration damage.
