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 eliminates the need for expensive ECU upgrades when expanding 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. Signal conditioning circuitry ensures clean, noise-free data transmission to your main ECU, critical for maintaining precise fuel delivery and ignition timing in high-output applications where sensor accuracy directly impacts horsepower and reliability.

Installers and tuners working with turbocharged, nitrous, or E85-fueled builds benefit most from the FT Input Expander's flexible input structure. Installation typically involves hardwiring to your fuel management harness and securing the module near your ECU or in the dash area, with detailed wiring diagrams provided by FUELTECH for your specific configuration. Compatibility depends on your existing FUELTECH ECU model and firmware version; consult FUELTECH documentation or contact their technical support to verify compatibility with your particular setup before purchase.
