Introducing my next car! 2008 Nissan Altima 2.5S CVT

It may help, it might hurt. Tuft testing is probably the best way to know for sure.

Okay, so I just made some great progress with the car recently...
First, I revised my grille block, now blocking off the fog light holes and blocking a cavity in the top of the upper grille for smoother flow...


And I finally got my UltraGauge mounted! It's not in absolutely optimum viewing position, but at least I can view it and grab data on the fly...



So far, I've learned that between 7 and 9% throttle(measured at the pedal, not the throttle plate) will hold speed at 50 to 55mph, with flash readings in the low to mid forties(MPG)

I've also learned that my Intake mod has resulted in IATs at around 10* above ambient, which isn't bad for a near free mod

As soon as i started driving with the UG, the onboard MPG readout(which was zeroed out when I bought the car) immediately started climbing... That's nice to see such a drastic change, since I've put like 3500 miles on the car...

I had my Ultragauge mounted in front of the vent and if I ran the heater on high the device started overheating.

That's part of why I'm so dissatisfied with my UG mounting location, but short of drilling my dash pad, I haven't got any other options

I'm new to CVT not sure if I missed it but what was the best way to accelerate in "D" for city driving. Also have you found an optimal cruising speed for highway driving. Besides highest speed at lowest rpm. Any quarks unique to this car I should prepare myself for? Lastly do you think the cars mpg gauge is accurate? I never really figured out how to fully set up my scanguge 2.

Did you figure out what the vibration was. I got a 2008 Altima and when I accelerate relatively slow I get what feels like a rotating vibration for a second or two. Never notice it if i accelerate a bit faster though.

[19bonestock88]

Hey! I've been gone a while... As to your question, there is a vibration in a lot of these Altimas, when accelerating at around 1200 RPM... I've just gotten used to it

On a side note, my car is showing early symptoms of CVT failure, so...

[MetroMPG]

Noooo!

What are you going to do??

[19bonestock88]

Well, I've removed the grille blocking and I'm gonna sell the car while it still drives... the casual buyer won't notice an issue and may get another 10-15k before complete failure...

I'm gonna try to buy a Saturn Ion just due to having free parts available and having Ecotec engine knowledge...

It's nice to have the luxury of a bit of time to locate a good candidate.

Auto or manual?
