Ken, when reading how you were going to put the charge termination under control of the driver, I was reminded of some hypermiling techniques where the driver can make a huge difference.
And if you consider the nature of THIS forum, the most cost effective mod is to adjust the nut behind the wheel.
So when someone blanketly says that CVT and Manuals are equal, I will always reserve the right to protest
They could not be more unequal IMHO. Especially in the context of ecomodding, where you can (and I have) go get a $300 parts car and install a manual trans and get ~ 50+ mpg TODAY.
