Dreamer, if what Ecutek is saying is true, i'll be the first in line to jump on their bandwagon. VVEL is a fantastic technology, but only when you can manipulate it. Otherwise we are just throwing boost out of the motor. Literally.

[QUOTE=JARblue;2278709]My Z is very friendly to tuners. In fact, the Z has a date with one next week. I overheard their phone call, and she was very polite :icon17:

Did he just like, Slap that ***... - Ludacris in Fast Five - YouTube :icon18:

I have a feeling it'll be a slap :icon17: She's gonna be the street driven Z guinea pig for the new ECUTEK software at a local tuner shop :tup:

Thought Z1 already cracked it.

How do you know that though? The VVEL system with a factory exhaust cam plus tuning the intake cam could be worthless. Looking at a lot, and I mean a lot, of boosted VQ37 motors and comparing them across the board to the VQ35 (DE to HR) we are seeing equal if not better gains when applying forced induction.
The VVEL system might create more power, but honestly it will be a larger expense, because you will need to incorporate an exhaust cam into the tuning mix to see true benefits.

Z1 is using Uprev which is currently in a pro tuner beta test phase.
And then if you believe ECUtek they claim Uprev is wrong with how they are tuning VVEL.

Is there any projections for HUGE gains with stock cams? Still kind of a moot point if you're not upgrading cams.

And I still don't see what he's complaining about.

IMO the only ones capable of truly understanding how the VVEL system works in the Z are the engineers who designed it. Everything else is just reverse engineering and a lot of guess work...trial and error.

From my understand, the exhaust cam is already quite aggressive with the Z. I'm sure it can be designed better as any OEM would never make anything too aggressive. But, full control over the intake cam should do wonders. Imagine being able to set your own profile, your own lift, your own duration with the flick of a mouse? Less overlap can already create more boosted power with gains for NA motors as well. Most of what VVEL does has to do with emissions. But, when we have control, that is the icing on the cake.

Also, with the recent exposure to osiris from ecutek, it is quite possible that we are leaving quite a bit on the table. DE and HR motors are making the same power with more boost. Imagine what our motors can do with that same amount. HP per PSI should dramatically increase.

Evo 9 guys shift the entire torque band to earlier in the rev range with no ill effects on the top end. And, this is with only controlling cam timing on the intake side. Imagine lift and duration as well.

Ok so potential for big stuff.

Z1 is already working on it.

What am I missing?

I completely agree op, worst 6mt in the business but I've already said that a bunch of times on here. I don't need to add on with my laundry list of issues

I am not too sure why you are even comparing the Evo/Sti to the Z? I had a mildly tuned IX and it put down 350whp. It doesn't matter what car it is, all turbo cars react different and better to mods, than any NA car will. Two toally different car types, and two different roads to modding ability.

I can shift this 6MT pretty quickly... dunno what the complaint is about there.

I can shift fast too, but I don't like clunky sounds and sloppy manual like this car. You basically have to have a perfect launch to no get smoked by a Toyota Camry v6.

Nissan should take notes from Honda on how to get a butter smooth stick shift
