Hello i have M62B44 E39 540iA 1996/6 with ME5.2 ECU. I read 32kb file from box with galletto 1260 and i send to a tuner. I got a .bin file back and try flash with 14.7V battery float.
But this came up saying "invio errore" which should mean "sending error". I use like this, what is wrong

I can only connect with hood connector.


Many thanks everyone. I am no car technician i do computers.
Regards
