Its bad clone, why dont you use a european clone rather than the chinese rubbish? This is what happens imagine if it kill a ECU?

[tuning73]

I do not think that it is so bad clone
after repairing can not read any ECU



but I have problem writing as described "error change speed '"

Hi, when it say error change speed, seems to be no connection with ecu, try disconect obd plug, will be same message.

maybe I explained evil
I managed to fix fg clone now reads all ECU k-line can bdm jtag ok test ok ( edc15 edc16 edc17 bdm jtag ecc.. perfect read write)
on some ECU can not write edc 16u34 (id ok read ok write error change speed)
marelli iaw 59f same error read ok write error change speed (bot mode read write ok)
edc16c39 fiat same error read ok write error change speed
edc16u1 id read write ok
marelli 6jf 6f3 id read write ok

I do not think it is hw problem if the law should also write
possible problem with the firmware or driver?
it does not happen to anyone in these ECU ?

From where did you buy your clone?
