For what its worth...
I have been able to confirm what GSXRSpeed said about the (!) light and VSA. Thanks to the cold weather my (!) light as come on a few times and I was able to test it yesterday.
Yesterday, I launched my car (in an isolated, empty, parking lot) with the (!) light present and while switching VSA on/off multiple times.
When VSA was enabled, it acted normally in trying to prevent my wheels from spinning.
When VSA was disabled, my tires were allowed ot spin freely until I let off the gas to gain traction.

I had just put a set of Potenza G019's on my wife's '07 sedan. We decided to trade it so I though it would be a great idea to swap her wheels and tires onto my '08 coupe. I noticed the tpms light and figured I would just pull a fuse the next day. (I don't need a light to tell me about my tire pressure)
Needless to say, the night AFTER we traded my wife's car in, I tried to pull the fuse for the tpms and the light stays on! I don't know if I'll get failed during an inspection for that light, but aside from having the stealership install new sensors, is there a way to outsmart the system? Can I actually remove the entire system?

i dont believe anyone has done that yet. to my knowledge its built into the ecu so you wont be able to get rid of it
as for passing inspection? probably not. its mandatory on 08+ models so its likely mandatory to pass inspection
So if it's in the ecu, I can't just remove the bulb b/c it'll show up when they plug into the diagnostic port, right?
Anyone have a quick guess at what the stealership charges for a new set?

but thats when you have a tire pressure light and NOT the TPMS light illuminated, the vsa will still function normally with a low pressure situation, but if you have wheels WITHOUT tpms sensors, the system will go into dummy mode and will keep vsa on as it thinks you are now driving WITHOUT wheels...
you can check this by swapping out the wheels with wheels without sensors
at least this is what happened in the 06RL i drove, it had no sensors.. couldnt shut a darn thing off

no he confirmed that IF you have the (!) light on, and NOT the TPMS light on, you can deactivate the vsa, but if you have the TPMS light on, you cannot deactivate vsa

i thought it was the other way around
@ wannabfast: im not sure if you read all of the original post, and im going to look at it again right now and make sure everything is accurate... but...
neither the (!) or the TPMS light will permanently enable or disable VSA.
edit: part of the original post was a little confusing regarding the function of VSA. I tried to clear it up a bit

well inflate your tires to 50psi and try it out.. ive seen this happen on about 5 cars at the dealership..
maybe the vsa function is different on the si than on other models

Nitrogen will help in that it is more consistent and does not fluctuate with air temperature. If you decide to get nitro, you must make sure that you get as close 98% pure or better. Anything less will not yeild any results. The installer should have a gauge to test it.

When installing the sensors into aftermarket wheels, it is best that the sensor sits flush with the wheel, but not necessary. The system will still function even if the sensor is not touching the inside of the wheel. It is important however to leak test the stem to make sure there is no air leaking from around the grommet.

I haven't seen it on Hondas yet, but I have seen it on GM's, Bmw's, and Nissans
