FiTech 93004 Go EFI 4 600 HP System Power Adder Black, w/CDI box

The retrofit fuel injection revolution has begun! FiTech is the leading name in EFI conversions for good reason, bringing not only economy to the market but simplicity through design. The switch to fuel injection has never been easier. FiTech’s technology is designed and developed using OEM level engineering and components. All throttle bodies have built-in computers and sensors, reducing the amount of wiring to route in your vehicle. You can run the system on only 4 wires and two sensors! The sensors are OEM style for proven reliability and easy replacement.

Go EFI 600 HP Self-Tuning Fuel Injection Kit

FiTech Go EFI Power Adder EFI offers all of the latest technology and tuning software via a simple interface touchscreen. Full control of the ignition system is available, including selectable RPM curves and boost/nitrous retard strategies. The Power Adder units are also laptop tunable and feature data logging capabilities to help you dial in your combo.

The FiTech ECU also controls several vital engine functions including dual adjustable electric fan controls, fuel pump voltage regulation to reduce noise and heat buildup, and an integrated fuel pressure regulator ensures the unit is always at the correct fuel pressure. The wet flow annular discharge design improves fuel atomization, distribution, and intake charge cooling, which is critically important for boosted engines.

A list of unique features of the FiTech 30004 Go EFI 4 Power Adder 600HP Fuel Injection System:

• Boost-ready throttle body
• Boost-ready ECU with 2.5 bar MAP sensor good for 21.7 PSI
• Nitrous control with a host of safety features and accessories for nitrous tuning
• Nitrous and boost specific target A/F target options
• Boost and nitrous timing retard strategies
• Dual fan control (can set at separate temperatures)
• Advanced hand held tuning mode enabled
• Pro laptop software allows complete tuning for professional tuners
• E85 compatible (30% reduction in HP capacity of fuel system and EFI)

You also get the standard features included in ALL of the FiTech Go EFI systems:

• Four high-flow injectors good for 600 HP
• Initial setup is quick and easy - simple touch screen selections get you up and running in minutes
• Self-tuning EFI - after startup the self-learning ECU immediately takes over and provides your vehicle with an optimum tune
• Basic install can be done with just 4 wires and 2 sensors to install
• ECU is mounted on the throttle body so there is NO external boxes, harnesses or relays to clutter up your engine compartment, saving you time and keeping things simple & neat
• Uses a Bosch 4.2 wide band O2 sensor while all other sensors are easily replaceable GM style parts
• Air/fuel ratios can be optimized on the fly as you drive! Try that with your carb.
• Throttle bodies have a completely universal base to fit any 4-bbl carb manifold
• Throttle linkage suits most transmissions
• Choice of three fuel inlet connections
• All Go EFI’s feature Voltage Control fuel pump control which reduces the voltage to the pump under low load conditions such as idle and cruise thus reducing noise and heat. This will extend the life of your pump and keep the fuel in the tank cooler and your ears from ringing!
• Go EFI features wet flow technology with a unique Swirl Spray Annular discharge design that assures COMPLETE ATOMIZATION! Check out our videos, you need to see it.
• Ignition timing can be controlled and adjusted on the fly from your touch screen controller
• Use of ignition timing control is optional and not required
• Will work with CDI box but not required to control timing
• Ignition timing control does not learn, and requires synchronizing distributor to engine with a timing light
• Built in fuel pressure regulator means no extra regulator to mount on your fire wall
• Air Conditioning idle speed input kick up

FiTech Go-Spark CD Ignition

FiTech EFI is excited to extend their 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.
