FiTech 93661 Go EFI 2x4 Aluminum Master Kit w/ InTank Kit

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 2x4 Master Kit

FiTech dual-quad 625 HP self-tuning fuel injection systems are 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.

The advanced FiTech self-learning ECU continually adjusts the fuel map to increase efficiency and performance, while still allowing the user to adjust inputs on their own via a easy-to-use touchscreen interface. The Go EFI 2x4 625 HP kits offer all of the features available to tune your naturally aspirated motor, including control of the ignition system. By locking the distributor in place, different timing curves can be selected via the handheld touch screen, or this function can be toggled off and ignition controlled separately through traditional methods. The FiTech ECU also has a built-in electric fan control, fuel pump voltage regulator to reduce noise and heat buildup, and an integrated fuel pressure regulator ensures the unit is always at the correct fuel pressure.

A list of features for the FiTech 30061 Go EFI 2×4 625 HP Dual Quad EFI:

• Includes 8 flow matched injectors capable of flowing 625 HP of fuel
• Dual high flow throttle bodies with mounting bases for Edelbrock or Holley style manifolds
• Die cast, tumble polished aluminum throttle body housings
• Throttle bodies have a base that will fit most dual quad or tunnel ram intake manifolds
• Includes polished stainless steel linkage that suits most transmissions
• Specific wiring harness for dual quad installation
• 4 Gig data logging
• Single electric fan control
• Initial setup is quick and easy
• Simple touch screen selections get you up and running in minutes
• Self-tuning ECU - 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
• Uses a Bosch 4.2 wide band O2 sensor while all other sensors are common GM style parts
• ECU is mounted on the throttle body so there is NO external boxes, harnesses or relays to clutter up your engine or dash, saving you time and keeping things simple & neat
• Choice of three -6 AN fuel inlet connections
• All Go EFIs feature Voltage Control fuel pump control that reduces 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 systems feature wet flow technology and have 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 a touch screen controller
• Air/fuel ratios can be optimized on the fly as your drive. Try THAT with your carb!
• Built in fuel pressure regulator means no extra regulator to mount on your firewall
• Use of ignition timing control is optional and not required
• Ignition timing control does not learn, and requires synchronizing distributor to engine with a timing light
• Will work with CDI box but not required to control timing
• Not compatible with nitrous applications
• E85 compatible (30% reduction in HP capacity of fuel system and EFI)

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.

Go Fuel In-Tank Fuel Pump Module

When it comes to converting to EFI, it’s important for the fuel pump to be installed in a cool area and what better place than in the gas tank itself. The pump is cooled by the fuel, it’s quieter plus there’s no chance of fuel starvation. To help ease the installation of an in-tank pump, this kit includes a new In-Tank Module assembly.

This universal billet assembly can be used on tanks with a depth of 6” to 15”. The billet aluminum was designed with the supply and return ports in a parallel position to help route the fuel lines easily and evenly. The vent port is on the other side to ease routing the line near the fill tube. The two fuel ports are threaded to accept -6 AN O-ring boss fittings for a secure, leak-free connection.

The cut-to-fit bracket secures a 340 LPH pump capable of providing fuel to 600 horsepower engines. To ensure clean fuel is pulled into the pump, two sizes of sock/filters are provided, a standard 11 square-inch design as well as a large, 35 square-inch version.

• Easily install a 340 LPH pump into most fuel tanks
• Adjustable for tanks from 6” to 15” of depth
• Billet aluminum top features -6 fuel bosses
• Low profile for improved clearance
• Supplied with seals, lines and filter/socks
