Firmware Reverse Engineering Guides & Technical Research

Assess embedded product risk through binary analysis, SBOM evidence and maintainability review. Scope firmware due diligence for acquisitions and supplier decisions.

Assess secure boot, firmware updates, rollback policy and recovery paths. Get a scoped review of how your embedded product accepts and runs software.

Recover knowledge from legacy industrial firmware when source code is missing. Define maintainable behaviour, replacement options and a verified recovery scope.

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 […]

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 […]

Complete guide to ECU PCB reverse engineering. Learn component identification, signal tracing, debug interface discovery, and schematic reconstruction.

ECU Firmware extraction is the foundational step in any ECU reverse engineering project. Without a reliable copy of the firmware binary, no meaningful analysis of calibration data, control algorithms, security mechanisms, or potential defeat devices can take place. Yet the method by which you extract that firmware profoundly affects what you obtain, how long it […]

The Toyota Hilux Gen3 Denso ECU (AN120/AN130) (e.g. microcontrollers R7F701202/702) introduced new hardware and software compared to earlier models. In practice, Gen3 diesel Hilux Denso ECU often use a 0–5 V MAP sensor scaled to roughly 0–360 kPa (3.6 bar), whereas Gen2 Denso ECUs were limited to ~250 kPa. This requires re-scaling tables in the firmware. Our team at […]

Whether you’re building a track ready machine or simply optimizing fuel economy on your daily driver, the right ECU tuning software can make all the difference. With 2026, tuning professionals and reverse engineers are turning to more versatile and precise tools that allow for safer, more powerful, and more customized calibrations. But which software stands […]

Calibration extraction, the reliable identification, extraction and validation of calibration tables from ECU firmware is a high-value technical capability required by tuners, OEM engineers, workshops and forensic practitioners. Done correctly it unlocks controllable, auditable changes to fueling, ignition, torque management and a host of engine control parameters; done poorly it risks mis-tuning, regulatory breach or […]
