I've recently started trying to reverse engineer my old car's ECU (2001 Holden Jackaroo/Isuzu Trooper with a 3.0L diesel 4jx1 engine), purely as a learning experience. I've managed to identify and dump the contents of the EEPROM on the board (AM29F200BT). You may have to bear with me as my knowledge in this department is very basic.
As I understand it, it will make it easier to reverse engineer the program stored on the EEPROM, if I manage to identify the main microprocessor and the code it uses. However I'm having trouble identifying the main microprocessor on the board. I've tried googling the numbers with no success.
Has anyone seen one of these before or can anyone point me in the right direction of working out which family of microprocessors it belongs to?
Thanks in advance.
