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

What you will learn

Module 4 introduces the emissions strategy layer of the Detroit Diesel GHG17 platform. The focus is not to list every switch, scalar or map that may be modified in an emissions solution. On some heavy diesel ECUs there can be hundreds of related calibration points. Instead, this module teaches how to recognise the types of map groups involved, understand what those map groups are doing, and see how the MCM and ACM interact across EGR, DPF and SCR strategy.

By the end of this module, you’ll understand:

• EGR Strategy in the MCM
• DPF Strategy Across MCM and ACM
• SCR / AdBlue Strategy in the ACM
• Complete Emissions Solutions

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: EGR Strategy in the MCM

• Focus:Identifying EGR strategy map groups within the MCM and understanding how EGR control can vary between ECU platforms.
• Key Takeaways:EGR strategies can involve switches, enable logic, PID control, hysteresis, targets and diagnostics, so learners should identify the relevant map structures rather than assume a single universal approach. EGR strategy should also be considered alongside DTC handling and torque behaviour.

Lesson 2: DPF Strategy Across MCM and ACM

• Focus: Understanding how DPF control is distributed across the MCM and ACM, including soot modelling, regeneration, doser control, pressure, temperature and diagnostics.
• Key Takeaways:DPF strategy is a combination of interconnected engine-side and aftertreatment-side controls rather than a single map or switch. Learners will use MCM and ACM map-pack references to identify the relevant strategy and understand its relationship with diagnostic handling.

Lesson 3: SCR / AdBlue Strategy in the ACM

• Focus:Identifying SCR and AdBlue strategy within the ACM, including dosing, pump and valve control, modelling, temperature windows and diagnostic logic.
• Key Takeaways:SCR strategy relies on multiple interconnected map types covering dosing, modelling, hardware and aftertreatment monitoring. Learners will use the ACM map pack to understand this structure and its relationship with diagnostics and inducement logic.

Lesson 4: Understanding a Complete Emissions Solution

• Focus:Bringing EGR, DPF and SCR strategy identification together to understand how a complete MCM and ACM emissions solution is structured.
• Key Takeaways:A complete emissions solution can involve numerous related changes across both controllers, requiring an understanding of the overall strategy rather than simply copying individual map changes. The supplied modified files provide reference outcomes to reinforce the method and logic used when developing a solution.

Who Is This Course For?

• Heavy Diesel Tuners looking to add Detroit Diesel GHG17 support to their service offerings.
• WinOLS Users wanting to transition from passenger cars to high-profit heavy-duty vehicle calibration.
• Fleet Technical Managers wanting to understand how professional economy mapping can drastically lower fuel costs.

Prerequisites

A baseline understanding of the EVC WinOLS user interface is recommended. Supplied training materials include original files, modified files, and the corresponding MCM map pack.
