Hey ppl,
Tuning an 808 in a gq off road truck, it's a stroked 5L,
Can connect and upload change etc when it's sitting there,
Can data trace when it starts for about 30 seconds and then
The data connection drops and cannot do anything further.
Have to unplug and shut RT Tuner and re open again
For it to establish a connection before re starting.
Have never had this issue before and at a loss,
Anyone have an idea?

I had his same problem.
It was the USB cable.

I have a spare I shall swap it out, thanx

try one with a ferrite bead on it if the current one doesnt have one.also make sure it has resistor plugs fitted

Good call guys, just tested it and it was the lead.
Only differed is the length, the one that is newer
Is about 2m long mine is half the length.
Thanx for the help never thought to change that
As it was new.
