Reprogram in truck much slower than at bench and I saw errors of bad connection
Also better to unpower all class2 data units cause they can interrupt communication
Thats why I prefer to reprogram at home
I use my PC as power source also (black gnd and +12 yellow wire from any unused PSU connector)
It takes me fastest speed in 1x mode (OBDlink not supports 4x)
