Jonathon- I have had the surges from time to time (on Evo Jet), however, I would turn the system off and also wipe down the dirty inside of the torque sensor. That would usually do the trick. In some instances, I would have to shutdown a second time. I also noticed it could trigger the system with surges when I am on very rough or bumpy terrain with excessive chain slap. I know, the bugs really suck sometimes...Hi Guys
