Resetting the AC, what does it do?
I am just curious as to what happens to the AC system after the reset? I did the AC reset as instructed on rx8blog.com. I do have to admit it actually works as my AC cycles less and it is noticeably colder.

I believe it just defaults to "reirc" anytime you turn the air on.
AC RESET:
1. Make sure the car is off AND the HVAC fan is off AND the A/C on/off button is off.
2. Press and hold the front defroster (on the left) AND air source (recirc/fresh air) buttons
3. Continue pressing the buttons in step 2 and turn the key to ACC for 3 seconds
4. Continue pressing the buttons in step 2 and further turn the key to ON (NOT START) for 3 sec.
5. Verify the programming update by observing the REAR defroster LED blink 3 times.
6. Release the two buttons from step 2 and start the car.

Changes the "duty cycle"
from
on-off-on-off-on-off-on-off
to
on............off...on............off...on........ .....
And puts AC in recirc mode whenever ambient temp is over 68F, temp set to min. and vents are in "face mode.
