All,

Have the 2010 ECM flash on my 09 Ss. Easy to notice the difference in fan management. However, it seems to have changed idle speed management a bit - essentially bumping the idle speed up 300-500 RPM when the bike is in gear. Go back to neutral and it settles back in around 1000-1100. Seems to run fine and I'm assuming it's an "improvement" to help off-idle performance, easier take off, etc. Anyone confirm this?

Yes all the DDFI3 bikes will raise the idle a tad to make it easier to take off.

The only downside I see is that it reduces the amount of engine braking available. Of course, with an 8 piston caliper out front, maybe I should just do my braking like a man...

I would find that obnoxious.

If you really hate it, you can adjust it.

Please see this thread regarding engine braking.

Froggy, great point. I was probably a little strong in terming it a "downside". I was actually pleasantly surprised that the XB was much less susceptible to wheel hop than my SV.

The road and the track are very different situations - horses for courses, it goes without saying. But for the road my preference is for more engine braking than the XB12 engine has - much easier to ride The Pace at a good clip if rolling off the throttle has a big effect on road speed.
