Direct from our precision manufacturing lines: advanced OLED displays, multi-function OBDII dashboards, and customizable sensor kits engineered for professional racers and tuning enthusiasts worldwide.
Modern motorsport demands high-fidelity, zero-latency telemetry to maintain mechanical reliability and optimize track strategy. Historically, racing dashboards relied on separate, heavy analog gauges linked by extensive wire harnesses. With the rise of modern engine control units (ECUs) and multiplexed digital communication protocols (such as Controller Area Networks or CAN-bus), instrumentation has evolved into integrated, intelligent, and lightweight glass cockpits.
As a leading Chinese manufacturer, Ruian DongOu Automobile Meter Factory has spent over three decades driving this technical transition. Integrating raw signal telemetry with digital processors allows custom racing dashboards to track, visualize, and log hundreds of channels concurrently. The modern market now requires display interfaces to show critical parameters—including exhaust gas temperature (EGT), oil pressure, wideband air-fuel ratios, and water temperature—while handling severe vibrations, high temperatures, and direct sunlight glare.
To achieve sub-millisecond screen update rates, modern racing dashboards rely on advanced microcontrollers that interface with the ECU and auxiliary sensors. The primary digital communication protocols include:
We design our dashboards with transflective LCD displays and high-brightness OLED screens. This configuration ensures visibility under challenging direct sunlight, while integrated warning alarms immediately notify drivers when parameters exceed safe tolerances.

Established in 1986, Ruian DongOu Automobile Meter Factory is a dedicated enterprise specialized in the research, design, engineering, and manufacturing of automotive instrumentation systems. Over nearly four decades, we have established stable production systems, a robust supply chain, and rigorous quality control workflows to serve both domestic and international markets.
Our business operates through a clear dual-brand portfolio designed to meet diverse customer needs:
To ensure high quality across our entire product range, our factory utilizes automated surface-mount technology (SMT) lines for PCB assembly, computer-controlled calibration equipment, and environmental chambers for thermal and high-frequency vibration testing. This rigorous testing guarantees that every dashboard and gauge functions reliably under high-stress track conditions.
We work closely with global racecar builders, tuning shops, and fleet owners, providing custom startup screen logos, unique housing designs, specific sensor calibration tables, and custom CAN protocol mapping. Our engineering team can adapt display units to interface seamlessly with proprietary aftermarket ECUs.
For street cars and weekend track day builds, our OBDII and Bluetooth-enabled dashboards, like the DO903 and DO921, offer a clean, non-invasive installation. They pull diagnostic data directly from the factory OBDII port, eliminating the need to run messy engine bay wiring.
From desert trophy trucks to endurance touring cars, our dashboards are designed to perform reliably under continuous engine bay heat, high G-forces, dusty environments, and direct exposure to moisture. They utilize dustproof, sealed connectors and shock-resistant internal mounts.
As motorsport shifts toward hybrid and electric drivetrains, the role of performance dashboards is expanding. Future dashboards must track battery temperature differentials, high-voltage battery state of charge (SoC), regenerator limits, and stator temperatures, alongside traditional parameters.
Our research and development program focuses on three main technological goals:
We work with international distributors, tuning brands, and professional race teams to provide end-to-end support for custom project requests:
