The project includes two main desktop tools: 1. **Diagnostic Scanner** Used for ECU diagnostic workflow, communication checking, and diagnostic reading. 2. **Remapping Flasher** Used for BIN file selection, file validation workflow, and controlled ECU remapping/flashing process. This repository presents the project as a ready desktop engineering application with screenshots, video walkthrough, documentation, downloadable application package, and safety disclaimer. --- ## Key Features - Windows desktop application for ECU diagnostic and remapping workflow. - Separate **Scanner** and **Flasher** application flows. - FTDI dependency through `FTD2XX_NET.dll`. - USB-to-K-Line hardware integration workflow. - Honda motorcycle ECU communication workflow. - Downloadable application package for review. - Screenshot documentation for UI, hardware, and architecture overview. - Video walkthrough for visual project presentation. - Safety disclaimer and local setup documentation included. --- ## Technology Stack | Area | Technology / Component | |---|---| | Programming Language | C# | | Desktop Framework | .NET Windows Forms / WinForms-style application | | Platform | Windows Desktop | | Communication Dependency | FTDI / `FTD2XX_NET.dll` | | Hardware Interface | FTDI USB Interface | | ECU Interface | USB-to-K-Line Module | | Target Workflow | Honda Motorcycle ECU Diagnostic & Remapping | | Hosting | Static HTML website | --- ## Repository Structure ```text ecu-diagnostic-remapping/ ├── README.md ├── DISCLAIMER.md ├── app/ │ ├── SCANNER BY FRENGKI.exe │ ├── FLASHER BY FRENGKI.exe │ └── FTD2XX_NET.dll ├── screenshots/ │ ├── architecture-diagram.png │ ├── flasher-ui.PNG │ ├── ftdi-device-manager.png │ ├── hardware-module.jpeg │ ├── module-framework.png │ └── scanner-ui.PNG ├── video/ │ └── ecu-diagnostic-remapping-walkthrough.mp4 ├── docs/ ├── data/ └── download-package/ └── ecu-diagnostic-remapping.zip ``` --- ## Application Files The desktop application files are located in the `app/` folder: ```text app/ ├── SCANNER BY FRENGKI.exe ├── FLASHER BY FRENGKI.exe └── FTD2XX_NET.dll ``` | File | Purpose | |---|---| | `SCANNER BY FRENGKI.exe` | Diagnostic scanner application for ECU communication and diagnostic workflow. | | `FLASHER BY FRENGKI.exe` | Remapping/flasher application for BIN selection and controlled flashing workflow. | | `FTD2XX_NET.dll` | Required FTDI communication dependency. | --- ## Screenshots ### System Architecture / Arsitektur Sistem ![System Architecture](screenshots/architecture-diagram.png) ### Module Framework / Framework Modul ![Module Framework](screenshots/module-framework.png) ### Diagnostic Scanner UI ![Diagnostic Scanner UI](screenshots/scanner-ui.PNG) ### Remapping Flasher UI ![Remapping Flasher UI](screenshots/flasher-ui.PNG) ### Hardware Module ![Hardware Module](screenshots/hardware-module.jpeg) ### FTDI Device Manager ![FTDI Device Manager](screenshots/ftdi-device-manager.png) --- ## Video Walkthrough The project walkthrough video is available in the `video/` folder: [Watch ECU Diagnostic & Remapping Walkthrough](video/ecu-diagnostic-remapping-walkthrough.mp4) ```text video/ └── ecu-diagnostic-remapping-walkthrough.mp4 ``` If GitHub opens the video as a downloadable file instead of playing it directly, please use the live website: [https://ecu-diagnostic-remapping.frengkipurba.com](https://ecu-diagnostic-remapping.frengkipurba.com) --- ## System Architecture / Arsitektur Sistem ![System Architecture](https://github.com/frnqpur/ecu-diagnostic-remapping/blob/main/screenshots/architecture-diagram.png) --- ## Diagnostic Scanner Workflow 1. Open the Scanner application. 2. Ensure the FTDI device and driver are available. 3. Connect the hardware interface to the ECU. 4. Start ECU communication. 5. Read diagnostic information or communication status. 6. Use the scanner result as a validation step before or after remapping. --- ## Remapping Flasher Workflow 1. Open the Flasher application. 2. Check FTDI and hardware readiness. 3. Select the compatible BIN file. 4. Perform file validation workflow. 5. Confirm wiring, ECU connection, and stable power condition. 6. Run the controlled remapping/flashing workflow. 7. Verify the result using the Diagnostic Scanner. --- ## Local Setup ### Requirements - Windows laptop or PC. - Compatible .NET Framework runtime. - FTDI driver installed. - FTDI USB interface. - USB-to-K-Line module. - Compatible Honda motorcycle ECU for full functionality. - Stable 12V power source for ECU-related operation. ### How to Run 1. Download or clone this repository. 2. Open the `app/` folder. 3. Make sure these files are in the same folder: ```text SCANNER BY FRENGKI.exe FLASHER BY FRENGKI.exe FTD2XX_NET.dll ``` 4. Run the Scanner application first. 5. Run the Flasher application only with proper hardware, wiring, and safety preparation. --- ## Download Application Package The downloadable package is available in: ```text download-package/ecu-diagnostic-remapping.zip ``` It contains the application files, required DLL, selected screenshots, documentation, and safety notes for review. --- ## Documentation Supporting documentation is available in the `docs/` folder, including: - User guide PDF. - View documentation. --- ## Safety Disclaimer This project is shared for technical review purposes. ECU diagnostic and remapping activities involve technical risk. Incorrect wiring, unstable power supply, incompatible ECU files, or improper flashing procedures may cause ECU malfunction, vehicle issues, or hardware damage. The following sensitive materials are not included: - Original ECU BIN files. - XDF/map definition files. - ECU backup files. - Source code private implementation. - Checksum logic. - Seed/key logic. - Sensitive flashing implementation details. Please read [`DISCLAIMER.md`](DISCLAIMER.md) before using or reviewing the application package. --- ## Result This project demonstrates: - Windows desktop engineering capability. - C#/.NET WinForms-style application development. - Hardware-software integration. - FTDI dependency handling. - ECU diagnostic and remapping workflow understanding. - Technical documentation and ready packaging. --- ## Limitation - Windows-only desktop application. - Full functionality requires ECU/FTDI/USB-to-K-Line hardware. - No complete standalone simulation mode is provided. - Remapping/flashing workflow should only be performed with correct technical knowledge and safety preparation. - Public repository is intended for presentation, not as a universal ECU flashing solution. --- ## Positioning This project is positioned as a **desktop engineering project** that highlights practical software-hardware integration, ECU workflow understanding, and technical documentation readiness.
