Haltech IO 12 Expander Box B CAN Based 12 Channel (Box Only)

What you get with this Haltech IO 12 Expander Box is the box itself, ready to expand your engine's data acquisition capabilities. This unit is designed to add 12 channels of input/output to your Haltech ECU system, communicating via CAN bus.

This expander box is a solid option for tuners and racers who need to collect more data. The CAN-based communication means it integrates smoothly with compatible Haltech ECUs, allowing for a cleaner wiring setup compared to running individual wires for every sensor. It's built to handle the demands of performance applications, giving you reliable access to more information about your engine's performance.
