APPLIED METHODOLOGY FOR READING, MODIFYING AND WRITING INJECTION MAPS IN AUTOMOTIVE ENGINE MANAGEMENT CONTROL MODULES

Abstract

This work addresses the topic of electronic control systems in modern vehicles, focusing on process management, calculation, and governance through Electronic Control Modules (ECU). It is highlighted that control systems use a variety of sensors and actuators to interact with the ECU, which executes control programs stored in special memories. The main objective is to propose a methodology to extract, modify and write the software of vehicle electronic control modules, allowing their operation to be optimized according to specific user needs.

The method is divided into several stages, including selection of control module by vehicle make/model and microcontroller manufacturer, determination of reading by different methods such as K-TAG, VVDI-Prog, etc., backup and treatment of the extracted information, file modification and checksum considerations, and the process of writing the modified records to the control module.

The application of the method demonstrates its effectiveness to correct specific emissions problems, using log reading and writing tools, as well as data comparison and modification strategies.backup and treatment of the extracted information, file modification and checksum considerations, and the process of writing the modified records to the control module.

The application of the method demonstrates its effectiveness to correct specific emissions problems, using log reading and writing tools, as well as data comparison and modification strategies. The paper highlights the critical importance of effectively managing software in modern vehicle electronic control modules, as well as the need to develop and apply practical and effective methodologies to address these challenges in the context of automotive repair and maintenance.
