Established in 1986, Ruian DongOu Automobile Meter Factory has stood at the forefront of the automotive instrumentation sector for nearly four decades. By combining deep research and development with scalable manufacturing, we supply race car parts and professional dashboards that satisfy extreme engineering standards.
Motorsport environments mandate sensors and display panels that operate under massive thermal fluctuations, continuous vibrations, and electrical interference. We have refined our proprietary hardware architecture to ensure real-time telemetry processing without delay. As a key partner to international tuning houses and global distributors, we maintain stable production pipelines that output components that excel in race-winning environments.
Providing specialized sub-brands tailored to high-end motorsport telemetry and customizable aftermarket tuning.
Jointly developed with an Australian engineering firm, SincoTech represents our premium line of professional racing dashboards. It delivers high-density data visualization, Bluetooth connectivity, and integrated OBDII systems to capture 9 to 18 critical engine parameters instantly.
GragonGauge focuses on high-precision modified instrumentation. This extensive line includes 52mm (2 inches), 60mm (2.36 inches), and 85mm (3.75 inches) tachometers, exhaust gas temperature (EGT) meters, boost gauges, voltmeters, and oil pressure displays with selectable multi-color backlighting.
We provide full branding flexibility. Clients can adjust faceplate designs, display scale dynamics, alarm thresholds, and warning tones. This customization allows wholesale distributors to maintain unique product positioning in target regions.

Procuring telemetry equipment for high-performance race vehicles involves managing strict tolerances. Procurement officers for race teams, specialty retailers, and niche vehicle converters face a common challenge: balancing sensor accuracy, durability, and cost-efficient scaling. Traditional consumer-grade gauges often fail under harsh track conditions, showing high latency or sensor failure. This can result in costly engine rebuilds due to undetected drops in oil pressure or overheating.
To address this, global distributors require hardware that features:
As a vertically integrated manufacturer, we mitigate supply chain volatility by producing key components in-house. We source premium microcontrollers, optical-grade anti-glare glass covers, and high-temp-resistant plastics to build instruments that resist yellowing, cracking, or losing calibration. By working with international shipping networks, we guarantee consistent lead times for large-scale wholesale orders and custom OEM batches.
Modern performance vehicle platforms are transitioning rapidly from mechanical gauges to digital display dashboards. Ruian DongOu has anticipated this shift by developing multifunction displays that interface with aftermarket ECUs and factory OBDII configurations. Our flagship dashboard kits, including the 10-in-1 OLED and 9-in-1 Bluetooth systems, act as central data monitors on the track. They display boost, RPM, exhaust temperature, oil pressure, and air-fuel ratios in a single, high-contrast display panel.
For modified drag and drift applications requiring sweep gauges, our high-speed stepper motors deliver smooth, immediate needle sweeps with zero latency.
We supply complete sensor kits, including electronic pressure transducers and high-accuracy thermocouples. This ensures that the instrument and sensor are perfectly calibrated to prevent signal drift.
Integrated Bluetooth interfaces remove the need for routing wires through the firewall. This simplifies installation, minimizes weight, and keeps engine bays clean.
Our long-term R&D path focuses on three core improvements: telemetry analytics, integration with external GPS tracking, and display performance. By incorporating 10Hz GPS modules, our future dashboards will overlay real-time engine data with lap timings and track positions. We are also transitioning our screens to thin-film transistor (TFT) panels with high nit values, ensuring excellent legibility in open-cockpit race cars under direct sunlight.
No matter where you are, we help bridge the gap between engineering and real-world performance.
The global motorsport and automotive tuning market has grown significantly. High-quality parts manufacturers are expanding beyond traditional European and North American regions. Fast-developing automotive cultures in Asia, Latin America, and the Middle East have driven the demand for premium racing gauges. This global reach requires suppliers who can deliver at scale while offering consistent quality across different borders.
To support this expansion, we have built a broad distributor network. We offer localized commercial terms, custom branding options, and tailored product manuals. Whether working with a distributor in Melbourne, a performance tuner in California, or a race school in Germany, we provide the localized support needed to meet market demands.
Operating internationally requires strict compliance with trade and safety standards. Our products are engineered and tested to meet international safety and emissions guidelines:
Engineered to adapt to any dashboard layout, steering column, or specialized console pod configuration.
Answers to common technical and integration questions for motorsport telemetry systems.
Our SincoTech Bluetooth dashboards use a dedicated 2.4GHz RF module designed for fast data transfers. They refresh in under 15 milliseconds, ensuring that critical parameters like RPM and boost readouts update in real time with zero noticeable lag.
Yes. GragonGauge modified instruments feature a dedicated memory control line. By connecting this line to the vehicle's headlight switch or dimmer, you can synchronize color changes and brightness adjustments with the factory instrument cluster.
Most of our kits include standard 1/8 NPT threaded sensors. We also provide BSPT and metric thread adapters upon request to match diverse engine blocks and sandwich plates.
Our wideband kits (such as the DO926 series) measure air-fuel ratios across a broad range (from 10:1 to 20:1) with high precision, making them ideal for performance tuning. Narrowband setups only indicate whether the engine is running rich or lean around the stoichiometric point.
Our OBDII-compatible dashboards work with most vehicles produced after 1996 that support standard OBDII protocols. For older race cars or custom builds without an OBDII port, we recommend using our standalone multi-sensor wiring harnesses.
