Technical guides and research notes on ECU firmware analysis, calibration workflows, boot and bench access, and related automotive reverse engineering topics.
Can you protect a transmission controller’s firmware while keeping it usable for programming and diagnostics? In this DQ200 project, we blocked the tested bench access path and prevented useful firmware extraction through the tested OBD read method. OBD writing remained available, and the client confirmed that VCDS diagnostics worked correctly. This case study explains how […]
ECU boot mode activation is one of the most critical steps in automotive firmware extraction. When standard diagnostic protocols are locked down, when read protection fuses block JTAG access, or when the OBD interface has been disabled, boot mode often remains the last viable path to reading the firmware from an ECU. Every major automotive […]
WinOLS has become the industry standard for ECU calibration editing, and for good reason. Developed by EVC Electronic, it provides a structured environment for viewing, identifying, and modifying calibration maps stored inside ECU firmware. But here is what most users discover quickly: WinOLS is only as powerful as the data definitions you feed it. Without […]
