I've tried yesterday many times but the program says to me to control connection or voltage, but the connection are 100% ok damn! :mad:

Then check you suplly voltage- sometime adapter go wrong voltage even on Original K-Tag. Do you give ECU +12 and - groung??

I've used a DC power supply :) first on ECU and then on K-Tag..
I've tried every combinations :)
Now i'm trying a trick with wire cable i think the istructions are wrong

[furnata]

Your K-Tag is clone or original??

[doctorx6]

I think I'm a stupid :)
The ECU could not be read because the pins where place the adapter have to be cleaned scratching a bit with sandpaper i didn't know it :wavey:
