The EZ-EFI Multiport Retro-Fit kit is offered to bring all the benefits of FASTs award winning EZ-EFI system to existing factory or aftermarket equipped multi-port fuel injected engine including GMs TPI engines, Fords 5.0L engines, and others. The kit includes:
Self tuning ECU Wideband oxygen sensor (with fitting and plug) Handheld user interface Tach adapter
Multi-Port wiring harness
The wiring harness is completely pre-wired and labeled for a simple installation. It includes connectors for early style GM sensors (coolant temp, air temp, TPS, MAP and IAC) such as those found on a GM Tuned Port engine. All of these sensors are available from FAST individually or in kit form. FAST also offers a Ford style TPS that is 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 from FAST to accommodate a later style 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 style injectors. Injector adapters or connector kits are available from FAST to adapt the harness to newer USCAR style injectors. The EZ-EFI system must be used with high impedance injectors. A wide range of high impedance injectors are available from FAST.
The EZ-EFI system must be used with a vacuum referenced fuel pressure regulator. Returnless fuel systems can not be used. FAST offers an adjustable regulator that is ideally suited for use with EZ-EFI. Various fuel system kits are also available. One in particular was designed specifically for the original EZ-EFI throttle body system. It includes, among other things, the FAST fuel pressure regulator, a fuel pump and a fuel pressure gauge. Also included is a fuel pump relay harness that is plug-n-play with the Multi-Port EZ-EFI wiring harness.
