Scroll down to the bottom of the file, you'll see something like this

Code:

PatternIncomingCall=1;3;0;0;30;970;0;1000;180
PatternIncomingMessage=3;3;2;2;30;470;0;500;154
PatternPowerKeyPress=5;5;1;1;0;16;0;16;128
PatternTouchscreen=10;3;0;1;16;10;15;50;255
PatternChatAndEmail=4;3;1;1;30;360;0;100;154

PatternIncomingMessage is the one for SMSs, edit that as you wish, if you want the same vibration as ChatAndEmail then copy the values for that into PatternIncomingMessage, i.e change from
PatternIncomingMessage=3;3;2;2;30;470;0;500;154
to
PatternIncomingMessage=4;3;1;1;30;360;0;100;154
Save, exit, then

Code:

stop mce; sleep 1; start mce

* You can use any editor for this
