3 Reasons to Consider a Self-Learning Fuel Injection System

3 Reasons to Consider a Self-Learning Fuel Injection System

Tuning is rewarding when you want to do it, but aggravating when you have to do it. Today’s self-learning fuel injection systems give us the best of both worlds. The injection units quickly learn what the engine wants to run at its best and offers additional tools for those who like to tinker.

Example images of throttle body and multi-port EFI kits

Which fuel injection kit is right for me?

If you’re tired of messing with jets and needles, replacing your carburetor with a Fuel Injection System has never been easier. If you make the right choices, the system will work great with engine you have today. It can also support your planned upgrades.

Carbureted vs. EFI: Fuelab

Carbureted vs. EFI: Fuelab Examines How Fuel Line Size Relates to Fuel Pressure Drop (and Why it Matters)!

Does size really matter when it comes to fuel lines? According to the fuel delivery system experts at Fuelab, it does. It’s because fuel line size and length have a direct effect on the amount of fuel pressure drop your fuel system will experience.

Choosing an EFI system that’s too big will result in poor idle and bad throttle response, same as a carburetor. Keep reading to learn what affects these ratings and how to pick the right kit for your motor.

Can I run a turbocharger, supercharger, or nitrous oxide with my fuel injection kit?

Power adders like nitrous, turbochargers, and superchargers are a natural fit with EFI. If you want to use power adders now or in the future, buy an EFI kit that is Power Adder Compatible from the start. A power adder compatible kit will work fine with or without boost or nitrous, and it might be impossible to make a non-compatible kit work with power adders. Unfortunately, not all power adder compatible kits are created equal. They usually have:

Can I use a fuel injection kit to control ignition timing?

Can I use a fuel injection kit to control ignition timing?

Most fuel injection kits will work with your existing ignition system. All they really need is a tach signal. Ignition Timing Advance can be handled Mechanically and/or with Vacuum, just like with a carburetor.

An example of 2 different in-tank style fuel pumps.

What type of electric fuel pump should I use?

Electric fuel pumps come in three basic types. As long as a fuel pump provides the Flow Rate your engine needs at the pressure your Fuel Injected or Carbureted system requires, it will work just fine. It is just a matter of deciding which one works best for your installation.
