3800 motor swap, and EGR adapter plate

[Kevin]

Hey all... quick question , would love some help with this one...
I'm just finishing up a motor swap in my 1988 buick Lesabre T-type... a 1997 3800 supercharged.. I'm using the stock 1988 computer from the original 3800 series I. The problem I face is that of the the EGR valve... the origial is the 4 wire digital and the new motor uses the linear egr with PWM and position feedback.. right now I just want to use a block off plate where the EGR valve was so I can get the car running, and then worry about making an adapter plate so that the old EGR will fit on the new mounting plate.. If I block off the EGR ports with a plate, and don't hook up the harness to anything.. will the computer sense this and not play with spark or fuel when the EGR is supposed to be engaged? I understand that when the EGR opens.. the computer compensates by advancing the timing and leaning out the amount of fuel?
should I worry, or will the computer take care of this in the mean time?
Your help is appreciated, response to me personally, or in the list would be great,
