I have a very cheap "eobd-1260" , inside it there's a FTDI chip and not much more

I read my ecu 5 times with good results, shall I proceed with the writing?

it's a EDC16C39, alfa 159 2.4 210cv

hummmm !
I think 1260 not work in CAN

probably not but the alfa is K-Line ;)

EDC16C39

filesize is 1MB or 2MB.

correct is 2MB, but some simple flashers can read and write only 1MB

si dovrebbe fare.....


EDITED BY THE MODERATORS -> si dovrebbe fare..... - you should do - Next time write in english
