The wizard automatically saves the best settings in the "MY LAST TUNING" preset on the
chassis and in the TuningWizard\ folder. However, it is recommended that you save it again using

Finally, if you experience problems or if you are not able to get satisfying results out of the
auto-tuning session, email a copy of your PCIeTuningSession.xml file to our Technical Support
team at techsupport-snt@viavisolutions.com. This file is constantly updated while tuning so you
can even send it while auto-tuning is running. The next time you open the tuning wizard, it will be
overwritten, so make sure you copy it before you open a new Tuning Wizard session again.
