ECU Read/Write & Reflashing Procedures

This lesson focuses on correct and safe ECU reading and writing procedures, covering workflows from OBD programming to Bench and Boot modes for ECUs with tuning protection.

You will clearly understand:

When an ECU can be safely read and written via OBD, and when Bench/Boot access is mandatory, especially for protected ECUs such as Bosch ME17 and EDC17
Essential best practices before flashing, including DTC checks, vehicle condition assessment, voltage stability, and proper use of a battery stabilizer
Real-world ECU read/write workflows using KESS V2 and CAS V2, including ECU identification, reading, writing, and handling virtual reads

The primary goal of this module is to ensure safe, reliable ECU flashing — avoiding ECU bricking, communication errors, or data corruption — and preparing learners for professional-grade ECU remapping work.

Torque Calculation and Monitoring Methods

This lesson explains torque-based engine control strategies, which form the foundation of most modern ECUs.

You will learn:

Why modern ECUs calculate and control torque instead of power, and how torque is used as the main control parameter
How the ECU combines torque requests from multiple sources, including driver demand, transmission, air conditioning, and auxiliary loads
In-depth analysis of the core torque-related map chain, including:
- Torque request
- Torque limiters
- Fuel quantity
- Injection duration and timing
- Rail pressure
- Boost control and their respective limits
How torque monitoring mechanisms work, and why incorrect remapping can trigger limp mode
How to tune torque maps according to ECU logic, avoiding torque-related DTCs and built-in anti-tuning protection strategies

This module helps you develop a structured and logical tuning approach, ensuring stable performance gains without compromising ECU safety systems.

Start of Injection (SOI) Control Strategies

This lesson focuses on Start of Injection (SOI) and explains why injection timing is a critical factor affecting engine power, fuel consumption, noise, and emissions.

You will learn:

What SOI is and how injection timing directly influences combustion quality
The effects of advanced vs. retarded injection timing on:
- NOx emissions
- Smoke and particulate formation
- HC emissions
- BSFC (Brake Specific Fuel Consumption)
- BTE (Brake Thermal Efficiency)
- Cylinder pressure and mechanical stress
How SOI maps are structured and controlled based on RPM, fuel quantity, temperature, and engine load
Differences in SOI strategies across no load, part load, full load, and auxiliary load conditions such as air conditioning
Practical guidance on reading and interpreting SOI maps in WinOLS (EDC17), including:
- Axis identification
- Factors and offsets
- 2D and 3D visualization
- Typical SOI progression logic
Why SOI tuning is a critical tuning boundary: incorrect calibration can lead to power loss or engine damage, while correct optimization can deliver noticeable performance gains—often at the cost of increased emissions

This module emphasizes precision and ECU logic, helping you tune injection timing safely while balancing performance, reliability, and emissions constraints.

Bosch ME9 Engine Control Unit Training (Petrol ECU)

This module provides a practical introduction to the Bosch ME9 (ME9.7) engine control unit, using real-world calibration examples from vehicles such as the Mercedes-Benz SLS, analyzed and modified using WinOLS.

Key learning points include:

Understanding the Bosch ME9 ECU architecture and how petrol ECUs differ from diesel control strategies
Identifying and analyzing real calibration maps in WinOLS, with a focus on correct axis detection, factors, and data consistency
In-depth study of spark advance strategies, including:
- Basic ignition timing maps
- Optimal ignition maps
- Multiple spark maps (commonly 12×16 or 11×16 tables)
- Why ME9 often contains multiple maps with identical values—and why all related maps must be modified together
Analysis and calibration of torque request, driver wish (pedal maps), and optimal engine torque, using both 2D and 3D visualization for logical tuning
A key distinction of ME9 fuel control:
- Use of Injection Base and Injection Correction maps
- Direct AFR adjustment via multiplication factors, rather than requested lambda maps found in many other ECUs
Practical tuning workflow combining spark, torque, and fuel calibration to achieve smooth, stable, and reliable performance gains

This lesson reinforces that while ME9 follows familiar Bosch torque-based logic, its fuel control structure requires a different tuning approach. Correctly balancing ignition timing, torque modeling, and fuel delivery is essential for safe and consistent power improvement on petrol engines.

Mercedes-Benz A200 Bosch MED17 Engine Management System

Overview of the Bosch MED17 ECU on the Mercedes-Benz A200, focusing on fast map identification in WinOLS using 2D view and right window. Analysis of core maps including Optimal Engine Torque, Spark Advance (16-bit), Driver Wish / Torque Request, and Requested Engine Load. Turbo control strategy covers boost target, boost limiter, and torque limiter, where Stage 1 tuning requires only a 5–10% increase without touching the compressor map. Explanation of Lambda/AFR maps (4096 = Lambda 1 ≈ AFR 14.7) and how to enrich mixtures for performance. Emphasis on Torque Monitoring, where synchronized tuning of torque–load–spark is essential to avoid limp mode.

Comprehensive Bosch ME9 ECU Training (Mercedes-Benz SLS)

This lesson delivers a full-scale practical training on the Bosch ME9.7 ECU, using the Mercedes-Benz SLS as a reference platform. All previously covered ECU principles are applied directly, with no change in tuning mindset—only deeper execution.

Key learning points include:

Understanding the Bosch ME9.7 architecture and how earlier ECU tuning knowledge transfers seamlessly to this platform
Advanced focus on spark advance calibration, where:
- Multiple 12×16 ignition maps (basic and optimal) exist
- These maps often contain identical values, making it mandatory to modify all related maps simultaneously during remapping
Detailed analysis and calibration of:
- Optimal Engine Torque
- Requested Engine Load
- Driver Wish (Torque Request)
  using 2D map views to maintain logical consistency
The key ME9 distinction in fuel control:
- Use of Injection Base and Injection Correction maps
- Direct AFR adjustment via multiplication factors, with no Requested Lambda maps present
Practical tuning workflow centered around spark, torque, and injection, ensuring all interdependent maps are synchronized

This module highlights that ME9 tuning logic is straightforward but unforgiving—stable and reliable performance gains depend on coordinated calibration across all related spark, torque, and fuel maps, rather than isolated changes.

Disabling DTCs on Delphi MT22 ECUs

This lesson focuses on directly locating and disabling Diagnostic Trouble Codes (DTCs) inside the Delphi MT22 ECU firmware, commonly found on Chinese vehicles such as Lifan and Leon, without relying on external DTC removal software.

Key learning points include:

Overview of the Delphi MT22 ECU architecture and common real-world use cases
Proper WinOLS project setup for MT22:
- 8-bit view
- FF display
- 4-column layout (using the W key)
Navigating directly to the DTC memory region at address 0x48005F
- Understanding the DTC table structure:
- Right two columns represent the actual fault codes
Left two columns act as enable/disable switches for each DTC
Practical method to disable specific DTCs by setting the corresponding switch value to 0
No need for separate DTC removal software or diagnostic tools
Typical applications:
- Oxygen sensor (O₂) faults
- Throttle-related errors
- Faults appearing after performance modifications or component removal

By the end of this lesson, students can safely and efficiently disable unwanted DTCs directly in the ECU file, making it a fast and effective solution for modified vehicles and markets where Delphi MT22 ECUs are widely used.
