Inputs and CAN Expansion Products

Every good tune starts with good data, and this range is where that data comes from. Inputs and CAN expansion products cover the hardware that feeds your Haltech ECU, from wideband oxygen controllers and CAN keypads through to adaptor looms, sensor connectors, expander plug and pin sets, and mounting adaptors.

Choosing between them comes down to what you want to measure and how the device talks to your ECU. Wideband controllers like the WB1 and WB2 send lambda over CAN, so a single pair of wires does the work of a full analogue run. CAN keypads give you clean switched control without a loom full of toggles. Adaptor looms and plug and pin sets keep every connection factory-tidy rather than spliced.

If your build has outgrown its onboard channels, expansion hardware is how you grow the system rather than replace it. Not sure what your platform supports, particularly across NEXUS and Elite? Get in touch before ordering. We build harnesses in house and tune Haltech systems daily, so we can tell you what will integrate cleanly.
