good morning, I have a problem when I want to insert a new map: up to now I have always gone, unfortunately yesterday while I was inserting a new map, the connection was removed and the car went into the control unit protection (without even being able to turn on the car). tried several times to make the switch, in the end I tried to hold the cable under pressure to the control unit with the hand, and the control unit under pressure to ODB port, and I managed to flash (if I did not hold it with the hand under pressure, in the lower left of the ktuner program I saw that it connected and disconnected continuously), as the disconnection problem (always in the lower left of the ktuner application) became intermittently red and green, even when disconnected from the car, it means that it is the cable that does it not connect optimally to the ktuner control unit? possibly, what kind of cable should I buy? the classics for smartphones?

sorry grammatical errors, I'm Italian

You're welcome to try another cable or contact support to send the unit in.
