FT Input Expander Connector Kit

The FT Input Expander Connector Kit is a specialized interface solution designed for FuelTech USA engine management systems that require expanded input capacity. This connector kit enables tuners and enthusiasts to add additional sensor inputs to their FuelTech ECU, supporting auxiliary sensor monitoring for boost pressure, exhaust gas temperature, flex fuel content, or other critical engine parameters. Built for professional tuning shops and serious performance builders, this kit bridges the gap between basic and advanced engine control setups.

The expander connector is engineered with precision-molded terminals and robust shielding to ensure reliable signal transmission in high-noise engine bay environments. FuelTech's input expansion architecture allows seamless integration with the main ECU harness without requiring proprietary adapters or lossy signal conditioning. The compact footprint—measuring 3.85 x 1.5 x 4.45 inches—fits cleanly into tight engine compartments, while the lightweight design at 0.08 lbs minimizes weight penalty. Quality construction and proper grounding ensure that auxiliary sensors deliver clean, accurate data to the FuelTech processor for precise fuel and ignition mapping.

This kit is ideal for builders transitioning from single-input monitoring to multi-parameter closed-loop tuning strategies. Installation requires basic electrical knowledge and compatibility with your specific FuelTech ECU platform—verify your unit's input expansion support before ordering. Tuners will appreciate the manufacturer's design focus on signal integrity and modular architecture, which simplifies harness management and reduces troubleshooting time during complex engine control builds. For turbo, supercharged, or alternative fuel applications demanding real-time adaptive calibration, the FT Input Expander Connector Kit is an essential foundation.
