No Data connection when vehicle running

Post by Thmpar »

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?

try one with a ferrite bead on it if the current one doesnt have one.also make sure it has resistor plugs fitted
If Its Got Gas Or Ass Count Me In.if it cant be fixed with a hammer you have an electrical problem

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.
