Chip tuning WinOLS Diesel ECU Remapping: Bosch EDC17

About this course

This course is your complete guide to Bosch EDC17 diesel ECU tuning. With 15 structured lessons, you’ll go from an initial ECU overview to mastering every major calibration map that controls performance, emissions, and drivability.We begin with a quick tour of the EDC17 structure—how maps are organized and how to navigate them efficiently. Then we cover Driver’s Wish to shape pedal response, followed by EGR control and EGR air requirement maps to manage recirculated gases effectively.Next, we dive into torque limitation and torque-to-IQ conversion, ensuring your torque targets align with injected fuel quantities. You’ll learn to manage smoke limitation for clean combustion and safe air–fuel ratios. The airpath section covers boost actuator (N75) control, boost maps, and boost limitation maps for precise turbo management.On the fuel side, we tackle injection duration, start of injection (SOI) across multiple maps, and fuel rail pressure for optimal power delivery and efficiency. Finally, we explore start maps that influence cold-start behavior and initial fueling.By the end of the course, you’ll have a proven workflow for finding, understanding, and modifying each map responsibly. You’ll know how to validate changes, avoid common pitfalls, and deliver consistent, professional results.For educational/off-road use only. Always comply with emissions and safety laws.
