Please excuse me for neglecting to read more deeply, but I just don't have the time to devote. Also, I think this would be very easy and fast for all of you who have participated in this thread to answer. I understand that the ECU has a motorola CPU which was mentioned in this thread.
I understand that a complete hexdump would give you a map of all the memory locations of this board from beginning to end, and that the assembly I'm seeing corresponds to machine instructions on the motorola chip
What I don't understand is where the formatting and comments are coming from. Am I to understand that there are tools that extrapolate enough from the machien language to write intelligent comments around the assembly, and that a programmer can use this as a starting poitn to refine?
Is this the executable code from the board which is run in real time? How much of the ECU is flashable? Are ECUs standard in any way across car manufacturers? How did you connect to this particular board? Is there a standard interface?
If there is a good resource I can read that would orient me to ECUs, and general hacking principles around this particular hardware, I'd appreciate it. How are things done in the world of ECUs?
