hi guys
first time i have cvt transmission
how much rpm is normal on 110km/62mph on hwy
what is the top gear when will it change to top
hhhhh

I only have experience on 2009 and 2012 models but they should be similar. In cruising, the rpm would be somewhere around 1800-2100 depends on the grade of the highway and head wind. The CVT will sense how much torque is required and adjust to optimal rpm. Also, when you accelerates, it will reduce ratio to go for higher rpm. This is the beauty of the Nissan CVT. It is not designed to race but in day to day driving, it is way better than conventional transmission.

the cvt does not control rpm, the throttle control/ecu does. When you step down hard on the gas, the ECU shoots the RPM into 3500-4000rpm for this engines, as this is its highest torque. the cvt only controls the gear ratio.

its possible to not shoot the RPM up, but to change the gear ratio = the transmission & engine computer's determine whats best, when.

At 110 km/hr on a flat grade your rpms will be right around 2000.

thanks
i saw it go about 2.5 for a while on 110
i release gas and pressed gas pedal again it was around 2
i don't know if this is normal

normal. it just held on to the "pre-load" mode until you released the gas pedal to let it know your calm.

The throttle only controls how much gas goes into the engine and how much accelerating power the engine exerts. In a lock-up converter, the transmission ratio controls the engine rpm for a given car speed. If the gear ratio goes higher, the engine needs to revolve at higher rpm to achieve the same speed (the torque to the wheels will also be higher for better accerleration). The main objective of having the transmission is to adjust the gear ratio to let the engine run at the optimal rpm for a given situation.

When you step down hard on the gas, the engine rpm is able shoots up only because the transmission (CVT) down-shifts to a higher ratio for better acceleration.

You couldn't be any more wrong......
1. the throttle doesn't tell the engine how much power to exert. it simply raises the rpm, or lowers it.

2. the throttle doesn't have anything to do with acceleration. if the gear ratio is wrong, you wont be acceleration anywhere even if you floor it. The acceleration power isn't in the engine, its in the transmission. The transmission is what takes the 175 lb-ft @ 4,400rpm from the engine and amplifies that power to be able to move a 3,000+lb vehicle. if you change the gearing in the transmission it will accelerate quickly but wont reach 100mph. change the gearing again and it will accelerate slowly, but reach speeds of 200mph

3. when you step down hard on the gas, and the CVT down-shifts to a lower gear - how do you think it knows to shift? BECAUSE OF THE THROTTLE! that proves that the throttle doesnt "only controls how much gas goes into the engine". The throttle not only sends "more or less gas into the engine" but it increases the throttle body air flow, increase the GPH flow rate of the fuel pump, it tells the transmission what gear it should go into and how long it should hold each gear(throttle 0%-50% = easy mode-&-change gears quickly / Throttle 51%-100% = hold gears longer & higher rpm).

im not going to get into it here as this is a 3day conversation. enjoy your rogue mate.

You have it completely reversed. The throttle is only one of the many inputs the CVT gets to determine the gear ratio and hence the rpm of the engine. The CVT will change the rpm even if you hold the throttle steady. It will change the gear ratio when the car goes up hill, down hill, enable sports mode, disable overdrive, down shift to "L" mode, etc.

Anyway, I won't waste any more time on this. Afterall, it is the "Driver" who controls the rpm.

Just to clarify for those reading and not aware: you down shift to lower gears. You upshift to higher gears.

your absolutely correct, my mistake. i was still trying to decipher what his actual message/intent/point if it all was LOL
