for the interface, you can use a simple integrated max232 with a handful of capacitors (on ****** there are different patterns in the simple) in such a way to create communication between ecu and pc, if you don't have a serial port you can use a usb converter ---> com.
power supply to bench the ecu:
pin 25: +12V
pin 34 -
pin 35 +12V
links interface ---> microcontroller ecu
pins 1-2-3 are connected together with mass interface
pin 17 is connected to the reset interface
pin 28 connected to pin TX interface
pin 29 connected to pin RX interface
to power the interface, you need 5V which you can take directly from the ecu, or with an external power supply, but remember to link together all the masses
once you have completed the step you have to do is open the program in administrator mode to avoid trouble, and follow the instructions.
For any other question, rest available, tried and tested on a dozen of marelli series 8 and 16f mounted on the fiat 600 and the punto mk1
