Skip years of trial & error. Learn tuning the right way.

Bad tunes don't just underperform. They melt pistons, crack ring lands, and turn a weekend project into a rebuild.

HPA breaks EFI tuning down step by step, taught by tutors who've tuned thousands of engines, set world records, and learned the hard way — so you don't have to.

These guys are unreal. What caught my attention originally was Andre offering up his expertise. He built and tuned the engine for DOCILE, the Evo that set world records and retired the fastest 4wd 4g63. I can see he’s now put together a crew of people equally as impressive in their own right.

What students say about HPA's teaching...

From people who started exactly where you are. With a free lesson.

Amazing tuning & engine building content! The quality and volume and frequency of additional content has left me truly impressed. HP Academy content is engaging, informative, entertaining and accurate! I am set for years to come with your stuff.

I was pretty apprehensive about paying for an online course but a day later and I couldn’t be happier. Finished the EFI Fundamentals course, and I’ve ended up with a good understanding of the systems and how they work. I’m now ready to install a new standalone ECU.

I really liked the quality of HPA, and the topics they were talking
about. But you always wonder “what will I get for my money and will the information be accurate?”. Well, Andre owned the fastest Evo in the world at one point, so it’s proven it works. For what you get for the money, it's incredible.

I have been building cars for many, many years, and have a solid understanding of engine function and have done my own EFI tuning for a couple years. Got invited to a free HPA Webinar and was impressed by the presentation of material, and the intelligence of the presenter. I highly recommend this program to anyone who wants to understand how an internal combustion engine functions, and how to properly tune it!

Frequently asked questions

Everything people ask before hitting the button.
What is EFI tuning and why is it important?
EFI tuning (Electronic Fuel Injection tuning) is the process of adjusting the ECU (Engine Control Unit) to control how your engine runs, from fuel delivery to ignition timing and boost levels. Done right, it improves performance, reliability, and fuel efficiency.
Will these courses work with my car or ECU?
Yes! HPA tuning courses apply to any tuning platform and any car. You can find several real-world tuning examples for several ECUs. And, we add new worked examples to our courses constantly to keep the information up to date — all completely free for course owners.
Which EFI tuning course should I start with?
Most people begin with EFI Tuning Fundamentals, which builds your foundation. From there, you can move into Practical Standalone Tuning, Practical Reflash Tuning, or Advanced courses depending on your setup. These courses are all included in our EFI Tuning Starter package, giving you a structured learning path to confident, hands-on tuning.
Can I learn EFI tuning even if I’m a complete beginner?
Yes, of course! HPA EFI tuning courses are designed to guide you step-by-step, even if you’ve never tuned a car or used an ECU before. Start with the fundamentals and build from there.
What’s the difference between standalone and reflash tuning?
Reflash tuning adjusts the stock ECU using third-party software and hardware, such as the HP MPVI3 module or COBB Accessport.
Standalone ECU tuning involves replacing the factory ECU with a fully programmable unit. HPA offers EFI courses for both methods so you can choose what fits your goals and vehicle.
What tools do I need to start tuning with?
The best tool to start with are these online courses! 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 it's even discussed in the courses for you too. It depends on the ECU platform you're using. These courses show you exactly what tools and software are needed, whether you're working with MoTeC, Haltech, Link, or a factory ECU.You can even start learning before buying any gear.
