Do I need to swap ICU when I swap motor?

So I am swapping the motor from an 03 tls into an 01cls and I'm wondering if I need to swap the ICU. I dropped both motors out the bottom and while it's out, I put on a new water pump/ timing belt, stainless steel headers and down pipe, CAI and new spark plugs. Also, the catalytic converter was gone, so I am running a straight pipe into a cherry Bomb for now. Anyway, its been a lot of work and I would like to know if the ICU needs to be swapped, while I have everything apart

Welcome to the forums.

The following is posted at the top of the New Member Introductions forum: Welcome! Please introduce yourselves here, BUT ASK FOR HELP IN THE TECHNICAL FORUMS

Since this is a topic/technical issue which will require replies and discussion, and not an introduction, this thread has been moved to the model specific forum.
