zach Posted November 9, 2020 Report Share Posted November 9, 2020 Have a new link g4x plug and play in a version 1 wrx. Problem I'm having is that my laptop is not detecting the link. Not even in device manager, No comp port or link or nothing. Correct software has been installed, laptop usb's ports operate other devices fine. ECU is not faulty and ignition is ON. Anyone incounted this before? Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 9, 2020 Report Share Posted November 9, 2020 Is the USB cable plugged into the correct USB socket (on the underside of the top board) and not one of the CAN sockets on the bottom board? I have seen users plug them in to the wrong socket before. Quote Link to comment Share on other sites More sharing options...
zach Posted November 10, 2020 Author Report Share Posted November 10, 2020 Just had the car tuned on a different laptop. Cant figure out why this mint as modern one is being difficult. Quote Link to comment Share on other sites More sharing options...
koracing Posted November 10, 2020 Report Share Posted November 10, 2020 Perhaps you need to "run as administrator"? i.e. right click on the Software and then click "run as administrator" from the options. I have had some weird issues with connecting before when remote accessing customer laptops and if I remember correctly this helped. Quote Link to comment Share on other sites More sharing options...
JamesM Posted November 13, 2020 Report Share Posted November 13, 2020 Laptop 1 year old & problems started after loading G4X PC Link. Could connect to G4+ & older as well as other ECU's no problem. Tried all ports, communication, baud rates etc no go. Laptop under warranty - replaced motherboard. All fixed. Tested again on G4+ & older all good. Bench tested G4X monsoon as was ok first time to unlock code. Plugged into vehicle - device manager showed as connected USB comm port. but Link G4X wouldn't connect. Updated firmware, updated drivers. Removed reinstalled G4X etc etc. So after 2 hrs with David Link UK & team viewer we found a pattern. Update firmware/ update drivers, disconnect & cycle power on ecu & laptop & reconnect & would allow connection - until I cycled key on/off on vehicle & wouldn't reconnect. Long story but fix was changed following settings in Device manager Device manager / port settings / advanced USB Transfer sizes Receive (Bytes) - set to 512 / Transmit (Bytes) - set to 4096 / Latency Time (msec) 2 / Time outs - Min read 100 - Min write 100 Can now connect & tune ecu - but is still bit clunky with process speed. Hope this helps Dave Clark 1 Quote Link to comment Share on other sites More sharing options...

zach Posted November 15, 2020 Author Report Share Posted November 15, 2020 The problem Im having is comp ports are not even showing up in device manager. When I install the software it clearly says that it's installed the drivers but there nowhere to be seen, makes no difference if link is plugged in or not. Other usb devices work fine and the link connects to my older laptop no worries. Quote Link to comment Share on other sites More sharing options...
koracing Posted November 16, 2020 Report Share Posted November 16, 2020 Definitely strange. I have to believe there is a software or driver issue on that laptop. I just tried plugging in a USB to serial adapter I have into my laptop and it immediately showed up in my device manager as COM6 under Ports (COM & LPT) as well as USB to serial converter under the USB controllers section. I don't have a Link ecu with me at the moment, but I'm certain it would do the same thing on this laptop anyway. Quote Link to comment Share on other sites More sharing options...
Dave Clark Posted November 16, 2020 Report Share Posted November 16, 2020 I've been able to connect an old laptop to the G4x but new now with latest version of windows won't entertain the connection........Will try the above to see if we can make a connection.
