Multi-Port Retro-Fit EZ-EFI Kit
Retro-Fit Includes: ECU, Wiring Harness, Hand-Held, & Wide-Band O2Sensor
Add Proven, Self Tuning EZ-EFI® To Existing OE or Aftermarket Multi-Port EFI Engines; GM TPI, Ford 5.0L & More
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.
*Directly compatible with the Multi-Port EZ-EFI® wiring harness without adapters, modifications, etc.
