Do it once, do it right
Fitting a standalone ECU into your project car will (usually) require a custom EFI harness to get it right — with the correct knowledge you can do this quickly, efficiently, and without costly mistakes.
Catch electrical gremlins
EFI problems often stem from wiring issues rather than the tune itself. With knowledge of wiring, you can quickly diagnose and fix problems like voltage drops, sensor failures, or poor connections.
Be the go-to-guy
Whether you’re wiring a street car project or aspiring to high-end, high performance teams, understanding wiring makes you more valuable as a tuner and electrical expert.

Damian FosterTheir Wiring Fundamentals course really shows in great detail concepts and practical demos on best practice when it comes to wiring your project. I cant wait to start increasing my library of courses as well as my knowledge in EFI tuning.

Steven Kirk-BurnnardI was pretty apprehensive about paying for an online course but a day later and I couldn’t be happier. Finished the EFI Wiring Fundamentals course, and I’ve ended up with a good understanding of the systems and how they work. I’m about to start the Club-Level Practical Wiring course, and keen to install a new standalone ECU and data logger and build my own harness.
