The VAG MED9.x Tuning Masterclass is a technical, hands-on course focused on Bosch MED9.1 and related MED9.x ECUs used across VAG 2.0 TFSI applications.The course starts with the architecture of the MED9.x calibration and explains how the ECU calculates engine load, requested torque and cylinder charge instead of treating boost, fuel and ignition as completely independent parameters.You will learn how the torque/load model works and how important calibration maps such as KFMIRL and KFMIOP interact with the rest of the control strategy. The course explains how requested load is translated into boost demand and how maps such as LDRXN participate in the boost request chain.Boost control is covered in detail, including boost request, charge-pressure limitation, wastegate/N75 control and the relationship between requested and actual boost. The course also explains why simply increasing a single boost map is not a complete calibration strategy.The ignition section covers the MED9.x ignition model, including base and optimal ignition maps, load and RPM dependencies, knock correction and the relationship between ignition timing, combustion stability, cylinder charge and fuel quality.Fuel and lambda calibration covers target lambda, enrichment strategies, component protection and the interaction between fueling, ignition retard, exhaust temperature and engine protection strategies. Particular attention is given to understanding why the ECU may intentionally command richer mixtures under high load or high thermal stress.The course also covers torque monitoring and intervention strategies, torque limiters, driver demand, gearbox-related torque limitations and the way torque modeling can influence boost and engine output.You will learn how to approach calibration changes systematically using logs rather than blindly modifying map values. Logging and interpretation of requested versus actual load, boost, ignition timing, lambda and knock-related parameters are an important part of the workflow.Additional topics include rev limiters, launch-control related strategies, deceleration fuel cut behavior, diagnostic functions, protection strategies and practical calibration considerations when modifying turbochargers, intercoolers, exhaust systems, fuel systems and other engine hardware.The objective is not simply to provide a list of MED9.1 maps, but to teach the logic behind the ECU so you can understand why each calibration change is required and how different parts of the MED9.x control strategy interact.Course focus:• Bosch MED9.1 / MED9.x architecture • VAG 2.0 TFSI calibration structure • Engine load and cylinder charge calculation • KFMIRL / KFMIOP torque-load model • Torque request and torque limitation • LDRXN and boost request strategy • Boost control and wastegate/N75 calibration • Lambda targets and enrichment strategies • Fuel system limitations • Ignition timing and optimal ignition maps • Knock control and ignition correction • Component protection strategies • Rev limiters and torque intervention • Driver demand and torque modeling • Gearbox-related torque limitations • Datalogging and calibration validation • Requested vs. actual boost/load analysis • Practical Stage 1 / Stage 2 / Stage 3 calibration strategy • Calibration changes for upgraded turbo and supporting hardware • Troubleshooting boost, fueling and ignition problems • Building a complete MED9.x calibration from a stock file
