his advanced course provides a technical deep dive into BMW Bosch MG1 ECU calibration and performance tuning using Bootmod3. The course focuses on understanding how the MG1 torque-based control strategy works and how different calibration maps interact to produce the final engine output.We cover the Torque &amp; Load model, including Maximum Torque Limit, Optimal Reference Torque, Full Load Torque Limitation, Maximum Filling, Torque Monitoring and torque reduction strategies. You will learn how to identify which torque or load limiter is actually controlling the engine and how changes in one area affect the rest of the ECU strategy.A major section focuses on load and boost control. We analyse the relationship between requested torque, load targets, boost targets, boost setpoints, actual boost and wastegate duty cycle. The course explains how the MG1 ECU calculates the required airflow and boost and how to identify situations where the turbocharger, wastegate control or ECU limitations prevent the requested target from being achieved.We also cover fueling calibration, including Lambda Target, Lambda Limits, HPFP target and actual pressure, LPFP behaviour, injection timing and fuel delivery. Particular attention is given to interpreting fuel-pressure deviations and lambda behaviour under high load to determine whether the limitation is calibration-related or caused by the physical fuel system.The ignition calibration section covers Base Ignition Timing, ignition corrections, knock control and cylinder-specific corrections. We explain how load, intake-air temperature, fuel quality, boost pressure and combustion conditions influence ignition timing and how to use Bootmod3 logs to identify abnormal corrections.A significant part of the course is dedicated to Bootmod3 datalogging and log analysis. We work with parameters such as:<ul><li>RPM</li><li>Load Target / Actual</li><li>Torque Target / Actual</li><li>Boost Target / Actual</li><li>Boost Setpoint</li><li>WGDC</li><li>Lambda Target / Actual</li><li>HPFP Target / Actual</li><li>LPFP pressure</li><li>Ignition timing</li><li>Cylinder-specific ignition corrections</li><li>Throttle angle</li><li>MAF / airflow</li><li>IAT</li><li>Fuel trims</li><li>Torque intervention parameters</li></ul>Instead of simply increasing boost or torque limits, the course teaches you how to read the ECU's decisions through the logs and determine why the requested performance is or isn't being achieved.We also demonstrate a structured iterative tuning workflow:Baseline → Datalog → Identify Limitation → Calibrate → Flash → Datalog → Analyse → RefineThis approach allows you to make controlled calibration changes while understanding their effect on torque production, airflow, boost control, fueling and ignition.<h3 id="d621a9c6-e152-4382-aa8b-4934dd454b66" data-toc-id="d621a9c6-e152-4382-aa8b-4934dd454b66" style="text-align: left; font-size: 20px; line-height: 1.2;">Course Topics</h3><ul><li>BMW Bosch MG1 ECU architecture</li><li>MG1 torque-based control strategy</li><li>Bootmod3 tuning workflow</li><li>Torque &amp; Load modelling</li><li>Maximum Torque Limits</li><li>Optimal Reference Torque</li><li>Full Load Torque Limitations</li><li>Torque Monitoring</li><li>Torque intervention strategies</li><li>Maximum Filling / Relative Filling</li><li>Load Target vs. Load Actual</li><li>Boost Target / Setpoint / Actual</li><li>Wastegate Duty Cycle</li><li>Boost control strategies</li><li>Turbocharger airflow limitations</li><li>Lambda Target and Lambda Limits</li><li>HPFP / LPFP calibration and analysis</li><li>Injection timing and fuel delivery</li><li>Base Ignition Timing</li><li>Knock control and ignition corrections</li><li>Cylinder-specific ignition analysis</li><li>IAT-related corrections and protections</li><li>Bootmod3 datalogging</li><li>RAM channel analysis</li><li>Log-based troubleshooting</li><li>Identifying active ECU limiters</li><li>Iterative calibration methodology</li><li>Real-world BMW MG1 tuning examples</li></ul>The goal is not simply to teach you which values to change, but to understand why the MG1 ECU changes its behaviour, which control strategy is responsible, and how to calibrate the system around real-world data.
