I have ticked grid maps in Atlas composer. The problem is my maps don't have same scale to represent. Then, I would like to configure grid in such way that lines of grid in different maps change automatically to each map in order will have better fit line.
I think that data defined override can be fix it. But I haven't seen this options to interval grid.

There's no option for data defined grid parameters yet, so unfortunately this isn't possible. You should file a feature request over at hub.qgis.org.
