Hi, I have the same issues when connecting to my PC. I am using the Android App instead now. Connections on my PC are crappy and unstable. It drops off when I try to read the map. Maybe try another PC?
Also, Tune ECU suggests that. so unless you can keep the voltatge above 12.5V,
" Occasionally it happens that the download is interrupted, although we have kept strictly to the
instructions.
It turns out that it comes to these interruptions, when the battery voltage falls below 12,5 volts,
even when connected a battery charger. Apparently the power of modern chargers is not sufficient
to avoid a voltage drop.
It works perfectly when a second 12-volt car battery is connected."
I would recommend to use the Android app as its more stable.
The problem was the charger I was using.
