FAST EZ-EFI Multiport Retrofit Kit

FAST EZ-EFI Multiport Retrofit Kit

This EZ-EFI Multiport Retrofit Kit provides all the benefits of FAST's award-winning EZ-EFI System to existing factory or aftermarket-equipped multiport fuel injected engines, including GM TPI and Ford 5.0L engines.

The wiring harness is completely prewired and labeled for simple installation. It includes connectors for early-style GM sensors as found on GM Tuned Port Engines (coolant temp, air temp, TPS, MAP, and IAC). FAST also makes a Ford-style TPS that's directly compatible with the harness (or the harness can be modified to accept any 0-5V TPS). The rest of the sensors need to be GM-style parts. Wiring adapters are available to accommodate a later GM TPS (round 3-pin connector) or IAC (in-line 4-pin connector). Also available are a remote-mounted IAC Kit and an adapter for installing an early GM IAC on a Ford throttle body.

The harness is wired for eight traditional Minitimer-type injectors. Injector adapters or connector kits are available to adapt the harness to newer USCAR-type injectors. The EZ-EFI System must be used with high-impedance injectors. The EZ-EFI System must be used with a vacuum-referenced fuel pressure regulator. Returnless fuel systems cannot be used.

Kit includes:
  • Self-Tuning ECU
  • Wideband Oxygen Sensor with Fitting & Plug
  • Handheld User Interface
  • Tach Adapter
  • Multiport Wiring Harness
