I/O Expander Boxes

Haltech I/O expander boxes are designed to increase the input and output capability of an ECU, allowing additional sensors, controls and auxiliary systems to be integrated into an engine management setup. This collection focuses on expansion hardware used when ECU capacity needs to grow to support more complex vehicle requirements across performance and motorsport applications.

Within this category you’ll find I/O expander boxes from Haltech, used to add extra analogue and digital inputs, outputs and control channels without replacing the main ECU. These expanders are commonly used for additional sensors, boost control, fuel system control, data acquisition and auxiliary functions as system demands increase. GameOn Motorsports supplies Haltech I/O expander boxes selected for compatibility, reliability and consistent performance in demanding environments.
