Go EFI 4 - 600 HP System
The Go EFI 4 Self Tuning Fuel Injection is rated at 600 HP but is suitable for engines from 250 HP thru 600 HP. This system is perfect for your everyday Driver right up to your weekend Street Machine or Bracket Racer. It features the FASTEST most accurate Self Learning available, Timing control, Wet flow Annular discharge and tons of additional features.
It fits any 4-bbl intake manifold and is the most self-contained and full-featured unit of this type. The ECU (computer) is mounted on the throttle body, which greatly simplifies installation. No hole in your firewall and no unsightly harness draped across your engine. This is also the only computer mounted throttle body that offers spark control without the need for an external spark box or special distributor. It also has a built-in fuel pressure regulator. A hand-held controller features a touch screen for quick and easy initial set-up.
(4) Hi-Flow 600 HP injectors.
Initial setup is quick and easy. Simple touch screen selections get you up and running in minutes.
Self-tuning** After startup the 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.
Uses a Bosch 4.2 wide band O2 sensor while all other sensors are easily replaceable GM style parts.
The ECU is mounted on the throttle body so there is NO external boxes or harnesses to clutter up your engine compartment or under dash. This saves you a huge amount of time and keeps things simple and neat.
Throttle bodies have a completely universal base to fit any 4-bbl manifold.
Throttle Linkage suits most transmissions.
Choice of three fuel inlet connections.
All Go-EFI's feature Voltage Control fuel pump control. This feature 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 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 your touch screen controller.
Air Fuel ratios can be optimized on the fly as you drive! Try that with your Carb.
Part #30001 & #30002 feature 1 adjustable fan control switch.
Will work with CDI box but not required to control timing.
Built in Fuel pressure regulator. No extra regulator to mount on your fire wall.
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.
Comments: While they make it seem easy to install, it's a bit more than just four wires. It isn't that bad, but plan your install first. The throttle linkage on old cars (linkage, not cable) doesn't always play well with the 'Holley compatible' linkage on the throttle body. I have a throttle linkage, a 700R4 TV cable and cruise control. The Holley TV cable brackets and linkage adapter both required modifications.
I would also recommend using an in tank pump with return line. The fuel command center can be problematic. I used my original 5/16 steel line for the return, so only one line needs to be run.
Consider adding a fuse to the fuel pump line, if it shorts out, the ECU is likely toast (Ask me how I know).
Lastly, if you want highly tunable timing control, buy the power adder version. This unit has basic timing control, but that's it
All in all, I really like this kit. It learns fast and is light years ahead of carb tuning kits.
