I’m running a fidanza light weight flywheel and a lower torque request at sub 2k will make starting off gently easier.

To what degree does the CAN on your engine and the CAN in your Boxster communicate? As mentioned the coolant sensor is a known CAN thingy, as is the speed sensor although we've seem to come up with a work-around. In my readings I understand that it may be possible to re-address some of the messages using the same tools used for Motronic tuning. So I'm wondering if you were able to do that.
The CAN stuff is something I'm not sure I want to deal with. I'm most likely going to sell my '03 S and buy a '97 Base for the swap to avoid all the emissions problems that I think could surface as a result of CAN mismatches. One thing in particular that I'm worried about is if the emissions readiness monitors are speed/distance dependent and then therefore, something that will prevent my car from passing the OBD smog test. Pre-99 cars in my area are permitted a tail-pipe test, which means I'll just throw a standalone EMS on it and be done with the whole thing.
Thoughts?
