Some functions can be recognized with me7info.exe which you can find here in the forums... Use this to enumerate the bytes/words(functions) etc.. that are already Generated by the script.Commenting next to them will also help in ida.
After that open a good definition file in ols and a good "Funktionsrahmen" for the me7 assuming that you are already familiar with the instruction set of the c16x cpu.But you never wrote what is your actual goal by doing this?
Search the forum a bit better and you will find all your answers and since you seem new to this this forum will cover almost all of your newbie questions.Do not expect to get always straight forward answers here on how to do anything...Just use the search button and your brains and you will find what you need.
thanks for your recommendation, I will look better in the forum, I am familiar with WinOLS, but did not know the ability to edit many functions in the bosch me7, this forum is opening me many ideas to implement in my car, I apologize for ask so I am just was enthusiastically of mechanics and electronics, I'm not a professional I'm not doing this with the intention of making money, on the contrary I have always invested my money to buy tools and work to learn from them .cheers
