or would you do it at the RPM of max HP ? ... would you slowly move it upwards from max torqu to max HP while increasing the gearing ?
any thoughts ?
That's the whole concept of the CVT's. However, it is much easier said than done. I've driven many different Murano's and a few different A4's quite a few miles in all of them and the vehicles don't stay at constant rpms. Try as it may, the variables to get the maximum performance, comfort, and gas milage all play a role in the fluxuation of the rpms. The tranny's rather work in rpm ranges for the given vehicle speed and throttle position.
If you could ef around and tweak the computer that controls the CVT, and work out a way for it compunicate with the ECU much quicker, then i don't see why your ideas couldn't be realized. Keep in mind i am in no way an engineer of this technology nor do i pretend to know more than the average person with an insatiable desire for knowledge could find out. These are just opinions of mine i have developed from personally interacting with CVT's and having access to some knowledgable people.
