EFI Tuning Fundamentals teaches you the core principles behind the engine operation, as well as the operation of the ECU. You’ll learn how the engine produces power, why it requires a specific amount of fuel, and how to decide what the optimal ignition timing is using the dyno. You’ll also learn how compensation tables work in the ECU and how to configure them correctly. You’ll learn how interpolation works in the fuel and ignition tables and learn how to correctly configure your tables for maximum accuracy without making more work for yourself.

This course will let you tune with confidence - With the knowledge from this course, you’ll be able to correctly calibrate the fuel and ignition timing even on engines that you’re tuning for the first time. You’ll be able to tune faster and more accurately while ensuring you retain engine reliability. While many tuners rely on the trial and error method of making adjustments, this course teaches you techniques that allow you to quickly and confidently dial in your tune without any guesswork.

EFI Tuning Fundamentals isn’t specific to any particular engine or any tuning software. Instead, it focuses on the fundamental principles that are applicable to any 4 stroke, gasoline engine. So regardless whether you’re reflashing the factory PCM on a naturally aspirated LS3, or you’re tuning a Honda K20 fitted with a turbo and a standalone engine management system, or any other combination for that matter - This course contains essential knowledge you need to know.

This course is theory-based, and while several examples are demonstrated on the dyno to help reinforce the concepts being taught, it won’t teach you how to perform your tuning on the dyno or the road. We offer this knowledge in our practical tuning courses, and they are the perfect accompaniment to this EFI Tuning Fundamentals course when you’re ready to start making your first tuning changes.

What you will learn
  • How an EFI system works
  • Essential EFI Components
  • How to optimise the Ignition Advance
  • What is Airflow and Volumetric Efficiency
  • How to choose the correct Air Fuel Ratio
  • Fuel and Ignition Table Resolution

What tools do I need to start tuning with?

The best tool to start with is this course! You need to walk before you can run, and the more you learn here the better you will understand the equipment you need for your application, and we even discuss it in the course for you too. This is not a 'secret' we're hiding, but rather us trying to make sure you buy the right tool the first time, and that comes from learning what you need first!

Will this also help me learn how to tune my carburettor?

No, EFI systems follow the same fundamental rules when it comes to tuning, but the way you make the changes using EFI and the fine control you have is very different to carb tuning to the point if you are tuning a car, you are unlikely to get much value from this course material.
