My Autel im608PRO is able to read many ECU types, but often there's no option to right back to the ECU chip. For example, I have a Bosch ME17.5.6 Volkswagen engine ECU.I'm able to read flash and EEPROM data from the bad ECU and it would be helpful if I was able to write data into a good ECU module. Same story with SPC56 microcontrollers.
