Explore our premium custom dashboards, gauges, and display modules engineered to provide low-latency diagnostics and vehicle telemetry.
We are a professional enterprise dedicated to the research, development, and production of automotive instrumentation systems. Since our inception, we have cultivated deep expertise in the automotive sector, building a mature, complete technical system and possessing stable and efficient production capabilities. We have established a strong reputation globally in the field of high-end automotive instrumentation.
Our dual-brand structure covers all aspects of automotive modifications and high-precision telemetry. SincoTech, our high-end instrument panel brand jointly developed with an Australian partner, focuses on the professional racing sector. Its stringent R&D standards meet the high-precision requirements of motorsport. GragonGauge specializes in modified instruments, including tachometers, boost gauges, vacuum gauges, temperature sensors, and voltmeters, spanning size specifications of 52mm (2 inches), 60mm (2.36 inches), and 85mm (3.75 inches).
A technical assessment of dashboard digitization, telemetry, and processing paradigms in professional racing environments.
In modern motorsport, driver efficiency relies on clean, microsecond-accurate data visualization. The traditional array of individual mechanical dials has been replaced by integrated digital clusters capable of parsing millions of data packets per second. These modern race displays interface directly with the vehicle's Engine Control Unit (ECU) via CAN (Controller Area Network) bus protocols. By shifting to a centralized digital console, drivers receive prioritized real-time alerts regarding critical thresholds (oil temperature, oil pressure, and exhaust gas temperature), allowing them to make split-second decisions with confidence.
Our SincoTech DO926 and DO909 series highlight this paradigm shift by incorporating high-brightness OLED and TFT screens that maintain readability in direct sunlight. These units process data from narrowband and wideband sensor kits, combining high speed and visual clarity.
The global push towards Electrification (EVs) introduces new parameters for racing dashboards to monitor. Instead of fuel levels and combustion temperatures, race displays must track battery pack temperatures, thermal runaways, cell balance, regenerative braking rates, and real-time state of charge (SoC).
As a leading manufacturer, Ruian DongOu is actively designing displays equipped with customized protocols to translate EV powertrain telemetry. This forward-looking approach ensures that our digital dash units remain compatible with both classic internal combustion engines and modern hybrid or electric racing vehicles.
Critical metrics that global buyers analyze when purchasing performance instrumentation components at scale.
Automotive retailers and tuning houses require custom start-up screens, tailored firmware profiles, and logo placement. We provide OEM/ODM services, adjusting scale parameters and backlighting colors to match specific brand standards.
A race display is only as good as its sensors. We supply complete sensor kits featuring brass housings and high-temperature wiring to prevent drift. Our systems maintain precision calibration even under extreme engine heat.
Open-cockpit racers, high-speed marine boats, and rally cars face water, mud, and intense vibrations. Our instrument panels feature IP65 and IP67 weather sealing alongside anti-vibration structures that guarantee operational longevity.
Leveraging advanced automation and localized industrial clusters to secure competitive lead times and component reliability.
Based in Ruian, the automotive components manufacturing hub of China, our facility operates a modern supply chain network. By integrating design, circuit board SMT assembly, enclosure injection molding, and calibration testing under one roof, we reduce lead times and minimize structural delays.
Our "Factory 4.0" initiatives feature Automated Optical Inspection (AOI) for electronic components, high-precision thermal chamber testing (-40°C to +85°C), and automated CNC finishing. This comprehensive quality control process ensures that every SincoTech and GragonGauge display system meets international performance standards before leaving our factory.

Export-grade race clusters designed to exceed motorsport tolerances.
Expert answers addressing the design, installation, and manufacturing parameters of custom dash displays.
Our racing display systems connect using standard OBDII interfaces, Bluetooth modules, or directly to aftermarket ECUs via CAN-bus lines. This enables real-time reading of core variables like RPM, speed, throttle position, water temperature, oil temperature, boost pressure, and air-fuel ratio.
Yes. As a direct manufacturer, we offer OEM and ODM services. We can customize the boot logo, modify indicator warning thresholds (e.g., configuring oil pressure warnings to trigger at specific PSI values), and adjust display colors to fit your brand identity.
Our GragonGauge modified product line includes standard pod diameters such as 52mm (2 inches), 60mm (2.36 inches), and 85mm (3.75 inches), matching most aftermarket dashboard pods, console brackets, and custom A-pillar mounts.
We operate under ISO9001 management protocols. Each display is subjected to automated SMT processing, optical inspections (AOI), high/low temperature calibration cycles, and mechanical vibration tests to ensure reliable operation under extreme race conditions.
