OEM/ODM wholesale products featuring premium OLED screens, OBDII connectors, dynamic sensors, and Bluetooth compatibility.
The global motorsports and sim-racing industries are undergoing a massive technological convergence. In the past, real-world track instrumentation and digital simulation setups operated in isolated ecosystems. Today, professional engineering dictates that racing dashboards support dual-purpose functionality. Whether installed inside a lightweight rally chassis or integrated into an advanced direct-drive simulator setup running iRacing, Assetto Corsa, or rFactor, the core hardware demand remains identical: uncompromised refresh rates, microsecond latency, and hyper-legible UI layouts.
As a leading manufacturing hub, Ruian DongOu Automobile Meter Factory bridges this gap. By utilizing advanced embedded system boards, CAN-bus microcontrollers, and wireless Bluetooth chipsets, our high-precision dashboards translate complex ECU telemetry (or local sim-racing telemetry packets) into real-time display actions. From shift light LEDs to dynamic oil pressure graphs, our hardware ensures drivers make split-second decisions without visual lag.
Our race dashboards utilize proprietary CAN-bus decoding structures. This ensures that parameters such as engine RPM, coolant temperature, boost levels, and exhaust gas temperatures (EGT) are computed within <5ms, preventing signal lag on critical track laps.
Through dual OBDII and Bluetooth protocols, our display clusters communicate seamlessly with standard vehicle ECUs, aftermarket standalone computers (like Haltech or Link ECU), and simulation software telemetry bridges.
Utilizing high-luminance transreflective LCD panels and state-of-the-art OLED modules, our dashboard screens remain readable under direct sunlight—a critical requirement for open-cockpit racers and high-end sim rigs alike.
Established in 1986, Ruian DongOu Automobile Meter Factory (branded globally as DONGOU) is a pioneer in automotive instrumentation engineering. For nearly four decades, we have focused on the research, development, and manufacturing of premium automotive gauges and telemetry systems.
Our operational ecosystem features two highly specialized divisions designed to target specific market niches:
• SincoTech: A high-end race instrumentation brand co-engineered with Australian partners, designed to meet the rigorous telemetry demands of motorsport tracks.
• GragonGauge: A versatile tuning brand covering 52mm, 60mm, and 85mm modified analog and digital gauges (boost, oil pressure, EGT, air-fuel ratio, and tachometers).
Our product matrix satisfies the performance demands of various professional industries and localized environments.
Esports venues and professional simulation centers require highly immersive telemetry interfaces. Our dashboard displays function as independent, USB-driven digital displays that map SimHub telemetry directly onto high-contrast physical screens, mimicking the cockpits of GT3 and Formula vehicles.
For real-world racers, the SincoTech DO907 and DO908 systems represent complete telemetry hubs. Equipped with waterproof aviation-grade harness pins and external sensor arrays, these dashboards monitor exhaust gas temp, water temperature, oil pressure, and wheel speed directly under heavy thermal load.
Custom machinery operators and special commercial vehicles utilize our 52mm double display gauges to monitor electrical systems and thermal parameters in real-time, preventing engine failure in heavy-duty utility industries.
How we plan to shape the future of telemetry hardware, combining AI analytics, modern protocols, and ultra-high-definition visual screens.
Transitioning our standard OBDII dashboards to support CAN-FD (Flexible Data-Rate) architectures. This allows for higher data throughput and microsecond accuracy in next-generation vehicle architectures.
Developing direct hardware-level firmware integrations for popular PC telemetry engines. Drivers will plug in SincoTech screens via USB and receive instant telemetry feedback without complex software mapping layers.
Phasing out older display elements for energy-efficient MicroLED and high-dynamic-range (HDR) OLED panels. These panels will output up to 1000 nits of brightness for perfect visibility in open racing environments.
Integrating low-power neural microprocessors directly into sensor kits. The system learns standard vehicle baselines and alerts drivers to anomalies before critical engine failures occur.
Industrial capacity backed by four decades of rigorous automotive gauge engineering and quality control systems.
With over 38 years of dedicated focus on automotive instrumentation, we have built deep industry knowledge, a mature technical system, and a solid reputation for reliability and efficiency.
Our two core brands, SincoTech for high-end racing and GragonGauge for diverse modifications, offer a complete and precise solution for every performance and customization need.
Our company provides customized automotive gauge services, supporting the customization of your own brand logo. We can also adjust the appearance, display range, and other core parameters according to your requirements.
