I just left Ecuador (2 days ago) and my entry permit was for 90 days. I am British, you do not say where you came from.
I suggest you will be in deep shit when you do eventually try to take it out.
The system is a computerized one so I would suggest it is unlikely you will be able to go under the radar.
When I left they looked my bike up on the system and printed off an exit authority certificate.
