Change TimeOut ?

Its edit the configuration file to increase the timeout time of loading maps?

For because of this so I can play on small maps (EX: Hijacked), and large maps, as it takes longer to load, timeout is giving direct and BO2 most maps are large and hard to find matches is small.

Could someone please help me with this, I can not stand this TimeOut direct most of the match.
