23:ech_tuner--Adjust Tuning Parameters

This option simply provides a centralised mechanism for viewing and editing the values of all the tuning parameters known to the system.

Most of the time it is more convenient to use the -option syntax from the main menu, as this only lists parameters used by the current default option.

In Option 23, any parameters used by the current default option are flagged with an asterix.

If, when used, a tuning parameter has a non-default value, an informational message is displayed.
