Elevate your heavy diesel tuning business with a structured, professional calibration workflow.

What you will learn

Module 5 brings the Detroit Diesel GHG17 course together into a complete solution workflow. The earlier modules separated the major areas of work: MCM tuning strategy, DTC logic, DTC table building and emissions strategy identification. In this final module, you will see how those areas connect into a professional sequence of work.

You will learn how an experienced tuner plans, checks, builds and reviews a complete GHG17 solution across the MCM and ACM, including recognising which work belongs in the MCM, which work belongs in the ACM, and why both files must be reviewed together when the customer requirement goes beyond engine-side tuning.

By the end of this module, you:

• should be able to explain and follow a complete GHG17 workflow from project preparation through to final review
• will understand how to separate MCM and ACM responsibilities
• will know how to build each side of the solution in a controlled order
• will understand how to check that the completed files remain logical, consistent and aligned with the intended outcome

Course curriculum

The module is structured into 4 focused, highly visual lessons (approximately 15 minutes each), complete with screen recordings of actual WinOLS modifications.

Lesson 1: Workflow Overview for MCM and ACM

• Focus: Establish a structured preparation workflow by separating MCM and ACM responsibilities before editing.
• Key Takeaways: A complete GHG17 solution requires treating the MCM and ACM as interconnected components rather than making disconnected changes. Effective project setup relies on clear customer requirements, accurate division of controller responsibilities, and systematic reference file usage. Proper initial preparation establishes the foundation for logical, safe cross-controller reviews in later stages.

Lesson 2: Building the MCM Side of the Solution

• Focus: Execute a structured, step-by-step modification and validation process on the MCM controller.
• Key Takeaways: MCM modifications must follow a strict sequence: engine tuning first, diagnostic structure second, and emissions logic third. Supporting maps and torque strategies require comprehensive checks to prevent isolated or incomplete edits. Reference files should serve as validation tools to ensure internal consistency throughout the MCM setup.

Lesson 3: Building the ACM Side of the Solution

• Focus: Review and manage aftertreatment, SCR, and DPF control strategies within the ACM.
• Key Takeaways:The ACM is a critical primary controller whenever a project involves aftertreatment, AdBlue, or DPF logic. ACM review requires a structured approach to map-type recognition, diagnostic handling, and emissions strategy. Proper ACM preparation ensures seamless integration during final cross-controller validation.

Lesson 4: Final Review of the Complete Solution

• Focus: Perform a comprehensive audit to validate consistency, safety, and delivery requirements across both file sets.
• Key Takeaways: Final validation demands a rigorous audit of both controllers as a single connected system rather than a surface-level file inspection. Thorough cross-checks ensure tuning logic, DTC handling, and aftertreatment changes are internally consistent and free from isolated edits. Professional project completion relies on clear documentation, clear validation plans, and alignment with original client requirements.

Who Is This Course For?
