The FAST EZ EFI system takes a lot of the guesswork and pain out of installing fuel injection on a non EFI equipped car or truck. Seen here with the FAST Holley-flanged throttle body, the EZ EFI system will also work with other systems like the one from Inglese, and pretty much any EFI system that uses GM-style sensors/plugs. Once everything is hooked up, just answer the system's basic setup questions through the pictured handheld display, then fire it up and drive around for a few minutes to let the computer learn the rest. You won't need any fancy programs or a laptop for tuning. The EZ EFI system also has built in diagnostics, and a "limp mode" to protect the engine in case of trouble, just like a modern EFI equipped car.
