Linking this here for visibility: done sorting out a good UpRev throttle map:
Smooth Throttle for UpRev
Another random note: my PC680 battery is finally failing. It finally crossed some line, and now I really only get a few good starts over a few days before it really needs charging with a good charger to top it off again (and even the good starts are little iffy). It was a good long run, but it's time to replace it. A new battery and some new electrical hardware (for better connectivity than the hackish first job) are ordered to arrive early next week, will post part#'s and pics after the install.
