Haltech Dash CAN Protocol

Haltech ECU Broadcast CAN Protocol

Technical Note

This knowledge base article was originally published as the Haltech CAN Dash Protocol. It has since been updated to document what is now known as the Haltech ECU Broadcast CAN Protocol.

The attached Haltech Broadcast CAN Protocol defines the channels and data streams that a Haltech Elite or Nexus ECU broadcasts over the CAN bus. This protocol allows connected display devices, such as Haltech dash displays (iC-7, uC-10), and aftermarket dash systems, to access real-time data from the ECU. Broadcasted channels typically include engine parameters such as RPM, throttle position, temperatures, pressures, and sensor data. By following this protocol, aftermarket dash displays can be configured to interpret and display this information, ensuring accurate monitoring and control of vehicle performance. This allows seamless integration across a range of Haltech and third-party display systems, enhancing versatility and ease of use.
