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 […]
Professional ECU reverse engineering and tuning for Honda engines. Custom ECU maps, torque limiter removal, and fuel optimization by ReverseEngineer.net.
Modern cars rely heavily on their Engine Control Unit (ECU) to manage engine functions, fuel delivery, ignition timing, boost pressure, and more. By adjusting the ECU’s software parameters, tuners can unlock more horsepower, sharper throttle response and better fuel efficiency. In other words, ECU tuning modifying the engine’s control program can significantly change performance. Two […]
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 […]
Popular ECU platforms and ECU tuning modifications offer significant performance gains to car enthusiasts. In the world of ECU firmware modifications, specialized updates that provide increased performance or a unique driving experience are quite popular. According to ReverseEngineer.Net, Stage 1 remapping, multi map modification, and launch control additions are particularly popular with ecu tuners and […]
DPF and EGR delete refers to the removal or disabling of a diesel vehicle’s Diesel Particulate Filter (DPF) and Exhaust Gas Recirculation (EGR) system, along with reprogramming the engine’s computer to run without these components. Modern diesel engines include DPFs and EGR valves as emissions control devices the DPF traps soot particles in the exhaust, […]
This case study covers a real-world Bosch EDC17 ECU tuning project, from extracting the ECU’s firmware to implementing a Stage 1 ECU tuning (performance remap) aimed at improving fuel efficiency, torque, and emissions compliance. The project scope was to unlock additional performance from the vehicle’s stock hardware without compromising safety or reliability. The client, an […]
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 […]
ECU firmware reverse engineering is a rigorous engineering discipline that begins with defensible evidence acquisition and extends through statistical map detection, emulation-backed verification and validated patch delivery. Our approach to ECU firmware reverse engineering emphasizes traceability, reproducibility and safety so that deliverables are suitable for OEMs, workshops and forensic teams. This article describes a formal […]
Seed-to-key Algorithms are a recurring challenge in automotive security, diagnostics and aftermarket tool development. When an OEM or workshop needs an interoperable diagnostic routine, or a retained technical capability to reproduce authentication flows, recovering a seed to key function from ECU firmware and supporting artifacts is often required. This article explains a proven, repeatable methodology […]
