Let me get out my spoon.

This is just some of the data. SGO also contains baud rate, seed key, everything you need to flash ECU.

Thanks a lot, now I see. Here is another interesting thread

Could you please point the offset of reset vector in the file I attached above?

80004372 is interesting. It checks the PC for whether it is running from flash or RAM, but the routine at 80004390 runs 6000 instructions before it sticks.

From a similar entry my MED17 runs 41000 instructions before returning.

I am still experimenting, but I'd consider multiple entries depending on the circumstances, but for finding cross refs I think I want to parse all the functions.
