CAN Bus & ECU Tuning: From Packet Analysis to Chip Remapping
CAN Bus & ECU Tuning: From Packet Analysis to Chip Remapping, Master CAN FD, AUTOSAR protocols, and ECU diagnostics using real-world packet captures and Wireshark analysis techniques.
Course Description
Welcome to the most comprehensive, hands-on guide to modern automotive communication and electronic control systems. As vehicles evolve into “computers on wheels,” the ability to understand, intercept, and analyze the data flowing through the Controller Area Network (CAN) has become the most sought-after skill in the automotive engineering and cybersecurity industries.
This course is designed to take you from a total beginner to a technical expert who can confidently navigate the internal nervous system of a vehicle. We begin with the fundamental physics of the CAN Bus, where you will learn the critical differences between dominant and recessive signals. You won’t just learn theory; you will see simulations of shorted networks to understand how real-world hardware failures manifest in the data.
Once the foundation is set, we dive into the Anatomy of a Packet. You will learn to decode standard CAN and the high-speed CAN FD (Flexible Data-Rate) frames used in modern Electric Vehicles and Euro 6 platforms. Using our exclusive 34-packet “Controller Arena” capture, you will gain hands-on experience with AUTOSAR NM (Network Management) and CanIf packages-the industry standard for ECU communication.
Moving beyond the wire, the course explores the high-stakes world of Electronic Systems Diagnostics and Chip Tuning. We pull back the curtain on how real ECU tuning happens, moving past the marketing hype to show you how fuel maps and ignition timing are actually modified within the Powertrain Control Module (PCM). You will learn to interpret Diagnostic Trouble Codes (DTCs) not just as “error numbers,” but as actionable data points.
Finally, we master the tools of the trade. You will learn the art of CAN Bus Sniffing, discovering how to safely tap into a vehicle’s OBD-II port or internal headers to capture live traffic. The course concludes with an intensive deep dive into Wireshark, teaching you how to filter, analyze, and reverse-engineer proprietary vehicle protocols. Whether you are an aspiring automotive engineer, a car enthusiast, or a security researcher, this course provides the technical blueprint for the future of transportation.
