Unable to connect to ECU with Laptop. 


ECU is a Vipec IPN35 Plug for 350Z 2004

Latest software has been download after being uninstalled and downloaded

Com port has been confirmed, Error Msg " Unable to connect to ECU but USB connection is present. Cycle the power to ECU " 

ECU was connected to few weeks back when at the tuners however now unable to connect. 

ECU has two Ports - One is a cable coming from inside ECU the other is the port the Racepak Dash was plugged into - this has been disconnected just incase that is also a issue, 

 Any help would be appreciated.

The USB port for the laptop would normally be the one fitted in the top of the case with the red o-ring as pictured below - unless someone has messed around inside.  I would expect the extra one that you say is "coming from inside" is probably the dash connection.
