I'm starting to think this crowd is starved for $EX? Is it because you ride Rockets (and your women don't)? Or, more simply stated, is it because you can't get anyone to ride your rocket?
Oh!! Yeah squish is awesome, but you gotta have the right amount. To tight and pop goes the weasel,to loose and the slug is like throwing hot dog down a hallway slappin all around in there.
It gives the bike an opportunity to learn its new idle conditions. When you make a change such as you did, the computer will need to adapt to the big gulps of air it can now get and the big pipe it can dump the exhaust into. If you just start the bike and go, it may idle poorly for a while. It would eventually relearn, but with the 12 minute tune, it gets most of that out of the way.
Right, and when you put an updated map in, you reset previous adaptations and run the 12 minute tune. Overall it gives a smoother transition to your new map, especially if it is radically different from the one your were using.
