Mitsubishi Lancer Evolution X 4B10 (ECU Part No. 1860B204) BIN File Share + Request f
Hello everyone, fellow Lancer modification and ECU tuning experts! I'm new here. Currently, I'm working on my Mitsubishi Lancer (manual transmission) equipped with the 4B10 engine, and the ECU part number is confirmed to be 1860B204. I'm posting this to seek help and share resources, hoping for guidance from all the experts here～
[Personal Situation Description]
I'm a beginner and currently developing an ECU solution based on STM32. So far, I have successfully read the original ECU BIN file of my vehicle using OpenPort 2.0 (followed the tutorial step by step, the backup is complete and undamaged). It has not been modified at all, purely original factory data, so you can use it with confidence.
The core problem I'm facing now: I can't find the ECU definition file compatible with 1860B204 (XML/A2L/XDF are all acceptable). I've tried definitions from several channels, but either the ROM ID doesn't match, or the MAP address is incorrect, making it impossible to parse the BIN file normally and proceed with subsequent calibration and debugging. I hereby seek help from all experts.
[Resource Sharing]
To facilitate communication among fellow car owners with the same model and ECU part number, and to thank all experts for their help, I am uploading the original 1860B204 ECU BIN file I extracted (see attachment). It is purely original and unmodified, compatible with the manual transmission Lancer 4B10 engine. It is for reference and definition file verification by all experts, as well as for backup use by fellow car owners with the same model.
[Help Request]
1. Looking for the ECU definition file compatible with 1860B204, preferably XML files usable with ECUFlash, A2L/Damos files usable with WinOLS, or XDF files usable with TunerPro;
2. If any expert has relevant definition file writing tutorials or MAP address lists, please kindly share them. As a beginner, I want to learn to make my own definitions, thank you very much;
3. If there are fellow car owners with the same model (Lancer 4B10, ECU 1860B204), you are also welcome to communicate with me about ECU flashing and calibration experience, and learn from each other for progress.
[Supplementary Notes]
1. The BIN file has been compressed and uploaded, no virus, no modification, purely original factory data, you can download it with confidence;
2. I promise that the shared BIN file is only for technical communication and learning among car owners, and is prohibited for commercial use;
3. If any expert can provide the compatible definition file, I will sort out a complete user tutorial later and feed it back to all fellow car owners to repay the community.

Thank you very much for the help from all experts! Wish all fellow car owners a smooth modification and a pleasant driving experience! 🙏
