ECU Reverse Engineering & Tuning Services deliver full-stack firmware analysis, calibration extraction, and secure modification workflows for modern automotive control units. We perform ECU firmware tuning, reverse engineering, and diagnostic forensics with OEM-grade precision, reliability, and traceability.

By combining low-level firmware analysis, hardware interfacing, and vehicle validation, we deliver tested ECU tuning and reverse engineering solutions for OEM, aftermarket, and forensic applications, from Bosch, Denso, and Continental ECUs to custom embedded control systems.

Core Services

Firmware Analysis & Mapping

We begin each ECU tuning project with deep firmware reverse engineering and calibration map discovery to enable performance, diagnostic, and emissions optimization.

  • Disassembly & decompilation (Ghidra, IDA Pro)
  • Function identification and callgraph reconstruction
  • Calibration / map extraction (fuel, ignition, torque)
  • Checksum and bootloader analysis

Hardware Interfacing & Dumping

We securely extract firmware data using industry-grade hardware interfaces to ensure accuracy and data integrity for tuning or diagnostics.

  • ECB / BDM / JTAG / SWD interfacing
  • EEPROM/Flash read/write with programmers
  • Secure access / seed-key analysis
  • Raw CAN / UDS capture and session logging

Secure Patching & Feature Development

We implement controlled and validated ECU firmware modifications for map tuning, feature integration, and secure performance optimization.

  • Immobiliser / ISN handling
  • Map tuning and multimapping
  • Performance and emissions feature integration
  • Firmware signing/validation assessment and safe flash procedures

Diagnostics & Forensic Analysis

We perform comprehensive diagnostic reverse engineering to uncover fault logic, DTC patterns, and runtime anomalies.

  • DTC analysis and event timeline reconstruction
  • CAN/UDS session forensics
  • Root-cause reports and mitigation guidance
  • Chain-of-custody ready documentation

Our Methodology

1

Evidence Acquisition

Secure, verified extraction of firmware and memory images with hash verification and chain-of-custody.

2

Static Analysis

Disassembly, string and data analysis, map detection and function recovery.

3

Dynamic Analysis

Instrumented execution, CAN/UDS session replay, and runtime observation (bench/vehicle).

4

Patching & Implementation

Controlled modifications, signature/CRC management and safe flashing procedures with fallback.

5

Validation & Reporting

Comprehensive test reports, before/after comparatives, risks, and remediation/release guidance.

This methodology ensures that every ECU tuning or firmware modification is traceable, verifiable, and tested in both bench and vehicle environments.
