How To Completely Disable The Routing?

Hi! I’m try Integrate Yii with WordPress like in this post:

It’s very cool use Wordpress and Yii actions in one application, but I’m faced with the problem - in admin part of WordPress no access to Yii app. I’m try to include Yii in admin.php, but Yii routs break Wordpress admin… How I can completely disable the routs in admin part of Wordpress, to use only models, components, views and Yii API without?

I’m think that I have to use another config to admin part, but I do not know how to turn off routing?

Or maybe I need to use some other way?
