Like quite a few of you, when I purchased my 08 Ultra, it had some TBW issues. At idle or at slow cruise, the RPM's would advance on their own from 2,000 to 3,000. They fixed this issue several months later with a new software download.. Until now, 12 months later, I have not had a TBW issue... Here is what happened next.... I was leading a group of bikes and was traveling over 50 MPH and the RPM's went to idle and the check engine light came on. I let the bike cool (it was 104 in Dallas) and reset the throttle... The bike worked fine for a couple days...and then it happened again...
Now they are replacing the induction module (under warranty of course)...but for those of you who have TBW ....this could be a scenario you may be faced with in the future.

Your first issue was an ECU issue, not a TBW issue. There is a difference. If a reflash fixed the issue, it wasn't a TBW issue. If it were a TBW issue, they would be replacing the induction module like they're doing with your second issue.
With that being said, I have ridden my brand new 2009 RKC in temps well above 104 already this year and there has been no issue with my throttle, either the ECU or the induction module.
I hate to differ with those who indicate my first issue was not a TWB issue... IT WAS and verified by HD. They indicated that the software program written for the first 08 Models had a programing error and needed to be corrected... The previous software program was allowing riders to reset the nominal idle condition during shut down...if they moved the throttle. Issue corrected with a new software update.
I am not faulting the TBW, I just had two issue related to the TBW system.
