    You would have to reach out to member 'TechRat' - unfortunately, he has not been active on this forum in a while.

    Sad to see TechRat disappear with an abundance of knowledge on the SR50's electronics, but it inspired me to start my own project in dumping and reverse-engineering to allow me to program my own DiTech's. I'd be curious if anyone else might be interested in such a thing nowadays.

    I've read a few different threads on the topic, is there one in particular you're referencing?

    AFAIK techrat never (publicly) shared the ECU dump or HC908 security key. I'm waiting on some parts, but it should let me defeat the security without needing to buy the Chinese programmer that he used.

    No, just wondered where you are coming from. Unfortunately, I do not have electronic skills to supply to the project, but I know that modifying the ECU has been considered the holy grail on this forum for a long time, and there has been some posts on it, but it has ended up nowhere.

    My suggestion for a new initiative would be if somebody could sum up everything that has been said and done on the topic, and then take it from there. Create a new post with this info, and then modify the first post as progress is made, people chime in on relevant old posts, discuss what could be the possibilities for progress and start a discussion on how it could be reached etc.

    I think that's the best bet if you want to engage people to work on it. Because now, the information is kind of scattered all around, and it is way harder to ask people to work on "it" if they don't have any background information, than to start an initiative that show them what the problems and suggestions for solving them could be, and then they can be inspired to contribute.
