Knox Posted September 18, 2021 Report Share Posted September 18, 2021 Hello, yesterday night I'm when on the dyno tuning an evo8 with plugin ecu. While I'm tuning something interesting happened. I noticed that car's door, my laptops serial port and my knock box's earphone have electric shock when I touch to them. And while I'm looking why is that I lost usb connection between laptop and ecu. Car starts and works fine so first I thought may be my laptops usb port burned but after that I tried another laptop and result is same no connection between laptop and ecu. After that I tried my laptop (which I use while this issue happen) with an other evo with Link plugin ecu and it connects to that ecu. So it looks like this ecu is works but can not connect to any laptop because of some electrical issue on the car. Is there any way to fix it ? Or someone have same issue before? If I can not fix this ecu here in Cyprus can I ship this to Link Ecu support department? Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 18, 2021 Report Share Posted September 18, 2021 Power the ecu up on the bench and try to connect as a confirmation. This will elimante any potential wiring issue. If you still cant connect like that then contact [email protected] to arrange inspection. Quote Link to comment Share on other sites More sharing options...
