FAST EZ-EFI Multi-Port Self-Tuning Fuel Injection Systems
FAST EZ-EFI multi-port self-tuning fuel injection systems are designed to easily run a GM LS Gen III/IV engine and transmission outside of the original vehicle and factory controller. They are the perfect no-headache solution for transplanting late model engines into street rods, musclecars, or other projects. Everything can be covered, from fuel and spark to engine and electronic transmission. Optional package stages allow you to select the right level of kit based on your individual needs. FAST EZ-EFI multi-port self-tuning fuel injection systems include all necessary sensors, a wide band oxygen sensor, wiring harnesses, connection cables, and a FAST XIM GM LS individual coil pack stand-alone ignition controller.
