FT INPUT EXPANDER

The FT Input Expander from FUELTECH USA is a compact signal integration module designed for advanced engine management and custom fuel injection tuning. This device expands input capacity for programmable engine control units, allowing fabricators and tuners to add multiple auxiliary sensors—such as secondary oxygen sensors, ethanol content monitors, or boost pressure transducers—without sacrificing primary ECU port availability. Built for hot rodders, LS swap builders, and serious performance enthusiasts who demand flexibility in their standalone fuel management systems, the FT Input Expander is a valuable tool for enhancing sensor integration.

This expander module interfaces directly with FUELTECH fuel management systems and accepts analog sensor inputs, converting them into formats compatible with your existing ECU configuration. The compact form factor—measuring 4.63 × 2.25 × 6.75 inches and weighing just 0.5 pounds—allows installation in tight engine bay environments common to custom builds and forced induction applications. It is designed to maintain precise fuel delivery and ignition timing in high-output applications where sensor accuracy is critical.

Installers and tuners working with turbocharged, nitrous, or E85-fueled builds can benefit from the FT Input Expander's flexible input structure. This module is particularly useful for those looking to enhance their engine management systems without the need for extensive modifications. Its design supports a variety of applications, making it a versatile choice for performance tuning.
