It wasn’t long ago that aftermarket fuel injection kits and systems were left to the engine builds with endless budgets or for owners with deep pockets. At best, even if the fuel injection were obtainable in the budget, tuning it would require a degree in physics and a hefty knowledge of algorithms; it involved running countless amounts of wiring, examining tables and curves, and practically designing your own fuel maps too. Let’s face it, they were a mess to install and flat-out expensive. Fortunately for us, that’s changed and these days, installing a complete system isn’t any harder than opening up the box, connecting some plugs, and turning the key to fire the engine. Yes, it really is that simple.
The old-school ideology of a carbureted system has been the norm for years and it’s always worked for us. Run some fuel lines, attach the linkage, and adjust the idle/air mixtures. Basically, a set it and forget it deal. Well, that same train of thought is still possible with FAST’s latest fuel injection system.
To get some firsthand experience with the system and its functions, we ordered one and tried it out on our latest 383ci build. The good news is, FAST’s EZ-EFI is capable of supporting up to 550 hp and includes their FAST ECU, a wideband oxygen sensor, the wiring harness, four fuel injectors, and a 4150-style throttle body, a fuel pump kit is optional. Simply hook up the four main wires, including any optional wiring for the fuel system, answer the basic setup questions on the supplied handheld display, and the system tunes itself as you drive. The beauty of this system is in its ability to seamlessly adapt and learn as a late-model car does. This means a foolproof system that will adhere to any driving situation while also reducing fuel consumption. Not only will this make everyday driving blissfully entertaining but reliable as well.
Make no mistake; this is the most straightforward fuel injection system we’ve ever tested. It was unbelievably easy to install and if you’re looking to convert your street mill to take advantage of modern-day fuel injection, you’ll be happy to know that FAST’s EZ-EFI is a complete plug-and-play system at its best.
