Not long ago, we wrote about the innovative FAST EZ-EFI, a bolt-on fuel injection system that eliminates the need for EFI tuning experience or the use of a complicated laptop set. The FAST EZ-EFI is a self-tuning fuel injection system that adapts to your engine on the fly and tunes itself. And now owners of multi-port fuel injected engines, including the GM Tune Port Injection, Ford 5.0L, and other performance engines; can enjoy that same award-winning efficiency, ease-of-use and performance.
There is no limit on horsepower because the system is based on each customer’s supplied injectors; it will run up to eight high impedance injectors to support a wide range of applications, everything from street through high horsepower. This performance kit includes a self-tuning ECU, wide-band oxygen sensor (with fitting and plug), hand-held user interface, tach adapter, multi-port wiring harness and everything necessary for a quick and easy installation. Simply hook it up, answer the basic setup Wizard questions on the included hand-held display, and the system tunes itself.
This hand-held unit also provides on-board diagnostics and a “check engine” LED display for maximum safety. Should the ECU lose signal from any of the sensors, the EZ-EFI® will revert back to its engine protection “limp mode”, allowing secure engine operation using the rpm input and any functioning sensors, although it can operate on rpm input alone if necessary.
The multi-port wiring harness is pre-wired for common GM sensors and labeled for a simple installation. However, FAST™ offers a full line of compatible sensors, injectors and adapters if needed. The EZ-EFI® system must be used with a vacuum-referenced fuel pressure regulator – returnless fuel systems cannot be used. FAST™ offers an adjustable regulator that is ideally suited for use with the EZ-EFI®, as well as various fuel system kits that include the regulator. Currently, the EZ-EFI system is for naturally aspirated applications only.
The FAST EZ-EFI Multi-Port Retro-Fit system (part number 302000) has a suggested retail price of $918.69.
