Problem solved.
St10 flasher 2.4b has a problem writing to a hex file but writes a txt file flawlessly. I wrote a simple program to convert it to binary. Got the whole 832KB out of the st10f276. Good for a free tool.
I wasn't game enough to try the clone mpps V12/13 as it bricked the ecu in bootmode when it gave an error erasing the flash. Galletto fixed it.
I've been searching all over what to do with a 832kb file and cannot find the answer. I have a ME7.1.1 Type 3, was able to get it into bootmode with a resistor on pin 24. I used MPPS v18 to do the dump, but no ME7 tools are happy with its outputs. I'm not sure what to do now.
