What is a CAN-based expander box?

A CAN-based expander box uses the Controller Area Network (CAN) bus for communication. This allows it to send and receive data efficiently with your ECU, reducing the amount of wiring needed compared to older systems and enabling faster data transfer.

What kind of sensors can I connect to the 12 channels?

The 12 input/output channels can be used for a variety of sensors and accessories. Common uses include connecting wideband O2 sensors, EGT sensors, or controlling additional components like cooling fans or fuel pumps, depending on your tuning needs.

Does this expander box come with all the necessary connectors?

Yes, the Haltech IO 12 Expander Box B comes with the required plug and pins to connect the 12 input/output channels and establish communication with your compatible Haltech ECU.
