'07 Idle Issues
But as far as the cruise problem, mine started doing the same thing on a trip home from the OBX. Guy riding behind me ask why I was bumping the brake so much, which was the problem. Every time I'd cross a bump the front brake switch would click and no more cruise. I took the lever off and barely bumped the part that makes switch (it's aluminum VERY easy to bend too much) and my problem was fixed. I'd guess you have the same problem with one of the two brake light switches.
Thanks though for your input
I haven't ridden the bike much but last year it developed the high idle issue. Wife and I were out for a ride came to a stop and the bike was at 2000 rpm and up.
What we did:
Relearn procedure on IAC
Cleaned IAC motor
Replaced Iac motors (Issue was gone last year but very very limited riding)
This weekends ride, put about 250 miles on the bike mainly highway and about 200 prior around the house. After the highway ride we stopped for a snack. When leaving I fired the bike up and got about 1 block and the high idle was back.
Now keep in mined this is a new IAC. The factory re-flash has no bearing I believe since it's a Zippers system. So now I have a new IAC a do not run the factory tuner and were back to square one.
I did spray the heck out of the IAC and after a short run it was working but still may act up every few stops. I drove all the way home with at 70 mph for 3.5 hrs and the idle issue was not there when stopping 3-4 times on the way home? I sure though it will come back.
For you, there's one more question mark since you have the T'Max instead of the stock ECM, although I doubt if that is the cause since this is a common malady on '07's with stock ECM's, and I've never heard of an ECM causing idle problems. I would call Zippers and ask them for ideas, as there may be something unique to their unit they know that we don't.
You could replace the TPS since it is cheap and easy to change out, as that would be my leading suspect.
Thank U I do appreciate your input.
Just my thoughts
After starting it up it jumped to 3k rpm like someone else said, however, after less than 2 seconds it dropped down to 1k rpm. Seems to idle fine, don't really notice a difference, but I haven't ridden it yet. We have 100+ degree temps today so I'm going to wait til later in the week.

On the way to work and from work yesterday, it idled down low when coming to a stop, almost stalling. Got home and took apart the air cleaner. I noticed that the butterfly valve had a ring of grease around the stops.....no biggie, just mild. But I opened the valve and cleaned it out well so the surfaces were all shiny. Gave a squirt of wd-40 on either side of the valve and the actuator. Also a tiny squirt up into the IAC.
Since just after buying the bike, I replaced the air cleaner with the K&N version of the stock filter, I went ahead and put the stock filter back on after cleaning it. I know, I should have eliminated one thing at a time....but
Put her all back together and went for a ride. Eevery stop the idle came back to 1K and stayed between 900 and 1K consistently. Put it up for the night and took the bike to work this morning - same route as always. Again no problems, idle never dropped below 900 or so...
I don't have a warm fuzzy that I have cured the problem, but I think that the general area of concern at least mechanically seems to be in the throttle body/IAC area.
Leaving for the big Sturgis haul in a few weeks, so I am going to give the bike to my stealer next week to have them check this issue all over, at least then I will know they are aware and possibly may find something more. The guy I got this bike from had no maintenance history to give me, so although it has 15K on it, I have no idea if he ever even brought it in after break in for idle and throttle cable adjustments.
Just thought I'd throw in my 2 cents. Great info on this thread by the way.

Also, it helps to cycle the IAC while you are spraying.
