How to Tune a Gasoline ECU with StageX: Module 4 of 4
Course Overview
In this fourth module of the StageX Gasoline ECU Tuning Course, you’ll learn how to make safe, calculated adjustments to the ECU’s control maps. From modifying load requests and limiters, through ignition timing and lambda targets, to torque and power monitoring — this module gives you the practical knowledge to apply changes with confidence.
This is where the theory from earlier modules becomes hands-on, showing you where to make modifications, how to apply them progressively, and why each step matters in building reliable performance.
What You’ll Learn
By the end of Module 4, you’ll understand:
- How and where to safely modify engine load request maps
- How to apply progressive changes to load limiters
- Where modifications should be made and why
- How to make safe, calculated changes to ignition timing
- How to find the optimum lambda setting and ensure it is targeted correctly
- How torque and power limiters must be adjusted in the ECU
- How to modify torque monitoring maps to support additional power
Who Is This Module For?
This module is ideal for:
- Tuners ready to progress from ECU strategy into practical modification
- Professionals who want to ensure tuning changes are safe as well as effective
- Students who have completed Modules 1–3 and want to put their knowledge into practice
