To start, I do not know if I'm posting in the right place. I am interested in starting to repair any car electronic ignition module and for that I need to have an idea of what instruments I need to acquire and, if possible, have module drawings, firmware of the same. I would be very grateful if you could, perhaps, have an ECU simulator diagram schematic to carry out the necessary tests.

Sorry for my English. You should find a "Service manual" for the car that you need to fix ...
