Performance Chip for CVT!!

[dubfly]

ok.

that sounds normal.

this is what i'm wondering...IF the rpms can reach the point where it is needed to receive maximum hp (245hp @5800rpms). it seems like nobody here on this site has made it up to 5800rpms (which is said where 245hp is given). i know there is way, i'm just wondering if anyone has gotten that high in rpms without changing the chip.

i guess it doesn't matter cuz i'm going to get the murano anyway!!! :lol:

I've gotten it up there. in the "D" mode.. all I did was (at a slow speed) put the pettle to the metel..

it's kept it up there for a while (at about 6000 rpm ) for about 20 seconds..
it took a while to get up from the running start, but it got there..

If I recall correctly the manual says the only time that "S" should be used is when going down a a grade...

I'll quote from the manual:

S (Second) position:

Use this position for the improved engine braking.

L (Low) position:

Use this position for maximum engine breaking on steep downhill gradients/climbing steep slopes and whenever approaching sharp bends. Do not use the L position in any other circumstances.


So, there is no such restriction for S csbey.

I've noticed that the computer seems to hold back the engine a bit, when you stomp on it from a standstill. For example, on my Maxima, if I punch it while stopped ( I have an auto) the front wheels will break loose and squeal, if the traction isn't good. Or pull really hard, if the traction is there...

The Murano seems to wait until it's rolling before allowing the power to come on full. Considering CVT's have not been able to handle higher engine HP's until recently, I suspect this is so you can't beat the crap out of the transmission by throwing full HP at it at a standstill.

Anyone see the same thing? This is based on a half hour test drive (alone) that I did recently. I'll be able to confirm it as I drive mine next week.

I'm not sure why they didn't design the CVT S mode to do the same thing. Drive around at 40mph at 3500 rpms and you'll see how annoying it is. I've used it a couple of times to enter an interstate. I guess the thought behind it is to alleviate the lag that you get in normal drive mode when you step on the gas.

I get between 20.4 and 20.9 MPG around town. Note, in my case around town means secondary roads, 30-45 MPH and few or no stoplights. On a
250 mi highway trip I get between 24-25 MPG. I drive with a light foot. :wink:

I read in February number of car and driver, and they got 7.5 on 00-60. Unfortunately, they were 7.8 and 5-60 mph. Im guessing the chip could improve, but I do not know much more than any improvement.

we got a mo about 3 mnths ago.my wife travels 80 miles a day.she gets arouns 22 mpg...as far as the second gear thing.i played with it at highway speeds.it makes passing at 70mph a breeze.it will just get gone instantly.puts thr rpms right around 6000 and takes off.i have also had it to 120 so far.lookin for more.our mo has no mods....yet

This thread is a few days shy of being 10 years old, going back to the when the MO was a recently-introduced model and the CVT was first being introduced to the American motoring public. It is interesting to read how the members back then were still in discovery-mode trying to figure out what the "S" on the shifter stood for and how the CVT operated.

As far as the performance chip for the CVT goes, it never happened. None was ever developed and it is doubtful one ever will be.
