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

What you will learn

Unlike basic tuning courses, this module treats heavy diesel calibration as a precise science. By the end of this course, you will be able to:

• Find the MCM DTC/SPN and patch-table regions without relying on completed self-built tables.
• Build the MCM DTC/SPN and patch tables, verify alignment and demonstrate controlled patching of selected MCM codes.
• Find the ACM DTC/SPN and patch-table regions from raw ACM data and verify that the suspected data is correct.
• Build and correct the ACM DTC/SPN and patch tables, then demonstrate controlled patching where the ACM data supports it.

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: Locating and verifying MCM DTC/SPN Data Regions

• Focus: Find the MCM DTC/SPN and patch-table regions without relying on completed learner-built tables.
• Key Takeaways: You will learn how to locate and verify the MCM DTC/SPN table data and the related patch-table data directly from raw MCM file data, using a mapped reference project as guidance rather than relying on a completed map pack.

Lesson 2: Understanding Tuner-Created MCM DTC/SPN Tables

• Focus: Build the MCM DTC/SPN and patch tables, verify alignment and demonstrate controlled patching of selected MCM codes.
• Key Takeaways: You will build the MCM DTC/SPN and patch tables from the raw data located in Lesson 1, verify their alignment, then demonstrate practical patching of selected MCM diagnostic entries.

Lesson 3: Locating and Verifying ACM DTC/SPN Data from Raw File Data

• Focus: Find the ACM DTC/SPN and patch-table regions from raw ACM data and verify that the suspected data is correct.
• Key Takeaways: You will learn how to locate and verify ACM DTC/SPN and patch-table data from raw ACM file data, using reference projects carefully while recognising ACM-specific structure and aftertreatment responsibility.

Lesson 4: Practical DTC/SPN Solution Methodology

• Focus: Build and correct the ACM DTC/SPN and patch tables, then demonstrate controlled patching where the ACM data supports it.
• Key Takeaways: You will build and correct the ACM DTC/SPN and patch tables from the raw data located in Lesson 3, validate the relationship, interpret existing 65535 handling and demonstrate practical patching of selected ACM diagnostic entries where the data supports it.

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.
