Here you are modifying `KIT` which is a module-level object, that might have unanticipated consequences. One possibility to avoid that would be to import KIT_AD and KIT_NY in the module, and then inside the function/method use

```Python
if sysname == 'New York University Abu Dhabi':
    KIT = KIT_AD
elif sysname == 'NYU 160ch System since Jan24 2009':
    KIT = KIT_NY
```
