    FiTech Go-Spark CD Ignition

    FiTech EFI is excited to extend its ignition offerings with the new Go-Spark CD Ignition! The all-new Capacitive Discharge Ignition will deliver high powered sparks from idle to top rpm to improve the combustion event and power output of your engine.

    The Go-Spark CDI was designed for both EFI equipped or carbureted engines and features a microprocessor to manage the spark delivery. The ignition, which is assembled in the USA, produces a series of multiple sparks below 2,500 rpm to improve starting, idle quality and throttle response. At higher rpm, the CD technology continues to deliver full energy sparks through racing rpm to ensure complete combustion of the fuel mixture. 

    The Go-Spark CDI is designed for 4, 6, and 8-cylinder engines equipped with a distributor. It accepts the trigger signal from an HEI, amplifier, points, or 2-wire non-magnetic pickup distributors. The tach output signal, which is also used to trigger a FiTech EFI system, is a 12-volt square wave signal that is divorced from other circuits to provide a clean, perfect signal.

    Not legal for use on pollution controlled vehicles. This system is designed to be installed into vehicles that do not require emission controls.
