Recommended Posts

Have a tablet hooked up to my link g4 via usb and went to turn on today and pop up shows in ecu screen saying, ecu not found, ecu definitly on as car starts/drives etc, tried new usb otg on the end aswell as new tablet, could it be the main cable from ecu to tablet?

In windows device manager do you have a Link ECU showing under Ports (COM & LPT)? similar to below:
