[Shotimes] Dyno charts

You are going to get the most pull at peak torque, not peak hp.

internal workings of the CVT's themselves.  The computer could track your
throttle position and speed and determine from that if you were trying to
maintain steady state speed or accellerate.  If you are trying to maintain
steady state speed, the computer can calculate what rpm is most efficient
for the engine in terms of fuel usage at that power level and tell the
transmission to shift as required to put the engine at that power level.
For accelleration it can do the same- determine what power level you want
and what engine rpm is best for that level of power output.  At some point
it would have to determine that the power output you want is beyond
efficient operation and begin transitioning to higher rpm's, all the way up
to eventually the rpm equating to peak horsepower at WOT.
