Infinity Quick Start Guide
A firmware update will erase the USB log channel list stored in the ECU memory. This
channel list will need to be reset before USB logging will function correctly. See Log
Menu for more info.
Troubleshooting:
If the process hangs at any point, wait at least one minute for it to continue. Some PCs
take longer to reconnect to to the ECU during this process. Some PCs may have other
processes running that affect the response time of the USB ports. If the process has
not continued as described above after one minute, do not cycle key power. Instead,
remove the USB cable from the PC, wait a few seconds then plug it back in. Often this
will force the OS to reset the port allowing the process to continue.
