and I did not flashed it, only trying to get connection only !

Luckily it was a just bought spare ECU, now is my question:

Can I try to read it with a galetto 1260 interface on the BENCH ?

If so, is there a connection diagram to do this ?

To be honest with you if going into business genuine tools all the way not worth the time and hassle fixing mistakes
But if on your own projects and cars I d say clone ( purely price wise cause your not gunna wanna pay thousands just to do your own might as well pay a professional but a cheapest v5, v12 Mpps clone do a lot of cars and about £30 at most nowadays you can pay £100 for a good quality tuned file and sorted

the original will not be problems, but with the clone do not know what to expect.

Often the Chinese clone is of poor quality. My opinion is worth more than the original purchase as well only spend money once.

good
I had three years Galletto original v2 interface is super but the support is zero
one year working with clone Galletto and are satisfied that the original, but I have update

Always original will be better than clone...
For some simple diagnostic clone it's enough but for professional and commercial use only original.

Im going to try the clone... fingers crossed!

be prepared if you will use clone ! ;)
