Description
How to Tune a Gasoline ECU with StageX: Module 2 Of 4
Understanding ECU Strategy — Learn How the Engine Control Unit Manages Torque, Boost, Ignition, and More in Gasoline Engines.
🧠 Course Overview
In this second module of the StageX Gasoline ECU Tuning Course, we take a deep dive into the underlying strategies used by the ECU to manage engine performance. You’ll explore how load, torque, ignition, and boost systems work together — and how these elements are represented in StageX maps.
This module is essential for anyone who wants to go beyond basic map editing and truly understand the logic behind modern ECU tuning.
✅ What You’ll Learn
By the end of Module 2, you’ll understand:
- The difference between engine load and boost pressure
- The relationship between requested torque and limiter maps
- How correction maps adjust for real-time operating conditions
- The role and structure of torque maps
- How the ECU manages ignition timing
- What knock control is and how it protects the engine
- The difference between Lambda and AFR
- How lambda maps influence combustion efficiency
- How the ECU uses EGT (Exhaust Gas Temperature) for protection
- Understanding rail pressure and fuel delivery logic
- How boost control is achieved through target and control maps
- The ECU’s control over the wastegate actuator
- How boost deviation and overboost conditions are managed
🎯 Who Is This Module For?
This module is ideal for:
- Tuners who want to go deeper into ECU logic
- Technicians working with turbocharged gasoline engines
- Students who completed Module 1 and want to progress to real tuning theory
- Professionals transitioning from basic map editing to strategy-driven tuning
