Default Can't get the UniSettings to communicate with the ECU... Can anybody help me out also...

Anybody here dick with APR Stage III settings? Not just timing or fuel but raising the boost a bit?

Thanks.

Default Yes USB cable for my VAG. Not sure I understand your second question as I am dumb..

I don't the RS4s are that maxed out that a pound or two more of boost is going to cause a dangerous situation.

The UniSettings recognizes the cable but when it starts trying to communicate with the ECU it says it cannot.

Default I had the same problem. Try rebooting your laptop and communicating with ignition on and engine off

I believe that you will not be able to add boost. It starts at 100% and only allows you to scale down.
