This is the driver that we (term used loosely :) ) are working on

It is not an absolute done deal but that is we we are headed towards. It's purpose is to have a suitable or acceptable moonlight and yet still have FET. ToyKeeper is a genius whereas the first three modes are on that 7135 and there is no voltage sag and the 7135 stays on except at all out turbo to minimize voltage sag on the FET.
This is the same driver PLUS the addition of a 7135. Although there already was dual PWM code available...ToyKeeper wrote one and tweaked the hell out of it :)
