Race Display Kit for OBDII Vehicles

The Dyno Racing DO903 kit provides a 9-in-1 instrument cluster that connects via Bluetooth to any second-generation OBDII vehicle. It shows RPM, speed, fuel level, throttle position, engine load, coolant temperature, supply voltage, current time and a selectable multi-function readout. The package includes the display host, Bluetooth OBD module, mounting rack and manual.

Bundled Module and Mount Expand Installation Options

The included Bluetooth OBD module transmits live ECU data to the display without wiring to the diagnostic port directly. The supplied installation rack secures the host unit in a visible cockpit position, while the manual details the setup menus for units, alarms, backlight and the multi-function display choices such as intake pressure, airflow, intake temperature or date.

Verify Vehicle Compatibility

Confirm the vehicle uses a standard second-generation OBDII protocol so the Bluetooth module can communicate. Ensure the electrical system delivers between 9 V and 16 V DC to meet the display operating voltage range. No additional sensors or wiring harnesses are included beyond the listed accessories.

Questions about this item

Will the Bluetooth OBD module need periodic re-pairing or firmware updates to stay compatible with my vehicle's OBDII system?

The kit includes a Bluetooth OBD module that communicates with the host unit; no firmware update schedule or re-pairing interval is specified by the manufacturer.

What is the first limit reached during continuous operation — display readability, voltage stability, or Bluetooth range?

The unit operates on 9V-16VDC vehicle power, so sustained use is limited by the vehicle's electrical system stability rather than an internal battery or thermal constraint.

Does the LCD backlight or the Bluetooth module generate noticeable heat or electrical noise during all-day use?

The host draws power from the 9V-16VDC supply and includes a backlight on/off setting; no heat output or electrical noise figures are provided for continuous operation.
