Set up below will do what you describe.  In this example I have assumed the switch/button grounds the DI when "on".  Launch control will remain active until the timer reaches 2 seconds (sorry I skimmed over your comment about 1.5 sec but you can set how you like).

Note however this is just going to give you an on/off type scenario, it may not be the best option.  I will mention another option just in case you didnt consider it:

A better option may be to set the launch mode to 3D, then put the timer on one axis of the table.  Then when you let the button go and the timer starts counting you can slowly increase the RPM limit as the timer counts up.
