When it comes to fuel injection versus carburetors, new school is just too cool. FiTech Go EFI 4 600 hp self-tuning fuel injection systems have the ECU mounted on the throttle body for greater self-containment, clean installation, and easy setup. These trick systems fit any 4-barrel intake manifold, and are designed for use on engines from 250 to 600 hp. They feature a built-in fuel pressure regulator, an ECU that takes command to find the best tune and self-adjusts to it—and the ability to change air/fuel ratios and ignition timing on the fly. To obtain complete atomization, FiTech uses a swirl spray annular discharge called Wet Flow technology, spraying the fuel in from multiple directions. Their systems with mounted ECUs offer spark control without the need for an external spark box or special distributor. To lower temperatures and extend the unit's life, FiTech uses a voltage-controlling fuel pump control to reduce the juice under low loads. Each system has a hand-held controller with touch-screen for initial setup, throttle linkage that suits most transmissions, and is manufactured with OE engineering. FiTech Go EFI 4 600 hp self-tuning fuel injection systems leave the guesswork behind, whether you're on the street or strip.
