FuelTech

FuelTech builds standalone engine management for everything from single-cylinder mini bikes to 12-cylinder drag cars and turbo jet skis. ASE stocks the FuelTech line next to its own JZ, K-series and ZF 8HP swap hardware, so the ECU, harness, sensors and ignition for a swap can come from the same place as the adapter plates.

What's in this collection

  • ECUs — FT450, FT550, FT550LITE, FT600 and FT700 standalone engine management
  • Wiring Harnesses — complete, unterminated and adapter harnesses, connector kits and CAN cables
  • O2 & EGT Conditioners — wideband O2 controllers, O2 sensors, EGT modules and thermocouples
  • Ignition Systems — FTSPARK CDI and SparkPRO inductive ignition modules, coils and harnesses
  • Fuel Injectors — high and low impedance FT Injectors plus peak & hold drivers
  • Fuel Systems — fuel filters, injector connectors and the parts that sit between tank and port
  • Switch Panels & Input Expanders — CAN switch panels and input expansion modules
  • Sensors & Valves — pressure, temperature, speed and chassis sensors, relays, boost valves and trigger wheels
  • Performance Accessories — fittings, steering wheels, mounts, dash inserts and billet intake manifolds
  • Water Sports — PWC harnesses and hardware for Yamaha, Sea-Doo and Kawasaki

How the system fits together

  • Start with the ECU. Every harness, connector kit and adapter harness is built for a specific ECU family, so pick the controller first.
  • Add a harness. Complete harnesses come pre-terminated for an engine family (LS, V8, universal 4- and 6-cylinder); unterminated harnesses are for custom builds.
  • Fuel and spark. High impedance FT Injectors run straight off the ECU; low impedance injectors need a peak & hold driver. Ignition modules (SparkPRO inductive or FTSPARK CDI) drive the coils.
  • Sensors and CAN accessories. Wideband controllers, EGT-4 modules, switch panels and the input expander talk to the ECU over CAN, which keeps analog inputs free for other sensors.
Running an 8HP swap? The FuelTech 8HP Transmission PCB Install Board sits in the Performance Accessories collection and pairs with ASE 8HP conversion kits.
