There is no arguing the popularity of EFI upgrades for classic hot rods. It seems every car owner is either spouting the virtues of squirting fuel or wishing they could. For that reason, I decided a great article about installing EFI would be a good idea for this Throwback Thursday.

As you know, each week we take a look back through the Power Automedia vaults and locate an article we feel is worthy of another look. This week, we are taking a trip back to March 2016, to check out FiTech EFI: What You Should Know About Your First EFI Conversion.

Fuel Injection Technology (FiTech) has met a goal to make EFI conversions so simple, all you have to do is bolt the unit to your engine, connect a few wires, and you’re set.

However, the first concern many have with an EFI conversion is whether it will actually be a direct replacement for their carburetor. Let’s quell that concern right now — it is. Of course, things like fuel pressure, wideband o2 sensor, and an ECU are part of the conversion, and FiTech takes care of including these items in its kits. There is additional wiring to add to the car, but that, too, is part of the kit and all wiring is terminated where it plugs into a sensor or fuel injector.

In the original article, we discuss how basic knowledge and skills are the requirement to installing your own system. If you can install a carburetor, water pump, or fuel pump, you’ve likely got the skills necessary to convert your engine to a FiTech Go EFI system.

FiTech’s Go EFI is an easy-to-install and use conversion for those wanting to do an EFI swap. It comes with everything you need, and you don’t need a computer.

If you’re adept with a computer, the Go EFI system has timing as well as fuel control capability, so the customer can manually tune if desired, The nice part about Go EFI is you don’t need to. The Go EFI is a complete self-learning system that does not require a computer for use. Enthusiasts should do only what they are comfortable with.

The basic connections for the EFI are a full-time 12-volt source, switched 12 volts, chassis ground, tachometer input, and an ignition input that sees 12 volts during cranking and run conditions. As for the ECU, FiTech mounts it directly to the throttle body, and all necessary sensors are either part of the throttle body — like air temperature, throttle position sensor, idle-air control valve, and fuel injectors — or they are included, such as the wide-band O2 sensor and the cooling-temperature sender.

Once installed, the casual passerby will have a hard time realizing an EFI swap has been made.

There’s a lot more in-depth information in this informative article, and we even show an install. So, what are you waiting for? Isn’t time to find out how easy it is to install a bolt-on EFI kit onto the engine in your hot rod? We think so, and for that reason, we selected FiTech EFI: What You Should Know About Your First EFI Conversion as this week’s Throwback Thursday showcase article.
