Thanks for the info on the closed loop mode! I did not know that. I was told that it does compensate and a remap is not necessary for just the A/C, but would be required for A/C and pipes or anything more significant like cams, etc.
The heat management only is for rider comfort, but the ECM can be remapped to run coolor over all. There is some leeway to run it a bit richer.... According to what I've been told. 
You MIGHT be able to get away with just the A/C, if you do not put a more open exhaust system on the bike, as it will only suck in as much as it can blow out, so total flow might not be affected...however, knowing that the bike is already lean to start with, that is something I would want to be certain about before proceeding. Be mindfull that I beleive very little of what any dealer says on these bikes, unless I'm talking to the most knowledgable tech they have in the shop...even then, I would be skeptical, as they do not see very many CVO bikes, so cannot possibly know all the in's and out's. This site is your best source of information about these bikes, bar none. Not enough people have the 08's yet to know much about what, if any, changes have been made to the systems, but that knowledge base will quickly develop here.
The ECM is able to compensate for enviornmental changes, but when you start messing with total air flow into and out of the engine, it cannot compensate enough for those kinds of changes. The SE A/C allows a fairly significant amount of increased intake air.
If it were my bike, I'd get a SERT and have it tuned with the A/C and pipes I want on the bike. If you want to break in with stock stuff, then make the changes at the 1K service, that would be a good way to go.
You can make the bike run richer/cooler, but it will take a SERT to do that, and a proper dyno tune. SERT is the only thing available at this time, and at this point I don't think anyone knows what can/cannot be done to the ECM with the SERT.
