Ok.....I've contributed several opinions and read everything I could find on:

1) IDS
2) Gearing noises
3) Engine detonation

and after my last visit to Dallas Harley Davidson, my bike runs like a different machine.

This may not apply if you have add-ons but on a box-stock bike, ECM reflash 32903-07E solved all my problems. Apparently HD came out with a "Torque Smoothing" mapping that resolved most IDS issues without the expense of adding IDS to 2007's. However, most bikes "pinged" at higher engine loads after having it applied. This could be avoided by riding "gently" but what's the sense in having a motorcycle if you can't get on it once in awhile, I queried of my dealer. :-)

Initially the dealer didn't knwo about this but after contacting "the mothership", HAD provided them with ECM reflash 32903-07E.

This is an upgraded (incremental) Torque Smoothing ECM flash, that made my 2007 Ultra a joy to ride. It runs like the proverbial "striped-assed-ape" now.

 

Is this a new flash?There wasa service bulletin on a ECM flash that I had done a few months ago...not sure it changed much. I also had one done for heat on the rear head.

 

Is that the same reflash that came out in the recall for pre november 07 models?

 

Maybe, I'm not sure...I think I had it done in January 07. I took delivery on my '07 UC in November '06. I could call Dallas HD and ask but I'm pretty sure how that call would go.

 

This is a brand new ECM flash. You probably have the "D". In fact, I sent another guy in the next day and another service writer didn't know aboutthis onesince it wasn't in the computer yet. Do call and ask for Service: Bill Ford. He knows about it.
