I tried disconnecting and grounding the battery, and it didn't work. A previous post stated that performing the battery disconnect and grounding resulted in a temporary fix, but I think the "fix" was a mere coincidence because my idle problem came and went at will, totally unpredictably.
For all the work I went through to replace the IACV (I followed the Honda service manual and removed the entire rear fender to allow clearance to remove the airbox) I would have prefered to replace, or reprogram the ECM, but the reprogram option wasn't available five years ago, and I had no information available then that replacing the ECM would work. My bike was examined by an authorized Honda dealer at that time, under warranty, and they performed a computer diagnosis that didn't find any errors. As luck would have it, the problem was not present when I delivered the bike to the shop.
I remember reading of your issues, having similar things going on...but mine was out of warranty by six months. I contacted Honda CS and they said since it was close, that MAYBE they would listen, but I had to go through dealership who said MAYBE 1 hour, maybe 5 hours at $125 per hour to diagnose. It needed new tires and was due for valve check...traded it in on Speed Twin, which in turn, morphed into having another go with the '17ex.
My true "out the door price" (everything including 4 years registration) for the '14 standard was $7000 and I got 4600 back. This was way before spike in vehicle prices overall. Owned it nearly 2 years, put 10k miles on it. Not ideal, but I think I saved myself a lot of running around as nearest dealer is 45 minutes away, over an hour if any traffic.
I am grateful that the ex has not had any issues related to idling.
