Particular Scripting Jsx

Hi !
for my effect trapcode particular, i would like changed the "Size Over Life" for the second preset.

actually, i access to values with setValue() like this for "Emitter Type" :

var solidLayer = curComp.layers.addSolid([1, 1, 1], "Particular", curComp.width, curComp.height, 1);

var particularEffect = solidLayer.Effects.addProperty("Particular");
particularEffect.property("Emitter Type").setValue(1);

but, it don't work for "Size Over Life". i tried with ([2]) too.
have you an idea for acceed to properties of "Size Over Life"?
Thanks
