ty! we don't know everything, and we try to be honest about that. And if we are not learning something every single day, I think of it as wasted

BTW, that's not VVEL but more VVT with WAY too much overlap down low.

As I said, we have not seen any real huge gains on the dyno, yet.

BTW, yes you can change the vvel with uprev, problem is, you have no idea what it is you are really changing, and not all of the tables are even defined with that sw. I try not to do stuff by wild assed guessing. If we can't repeat it, and back it up on the dyno, it does not go into one of our files. I really don't like to blow stuff up, it hurts my feelings!

Do you think there's gains to be made dialing out some of the overlap on boosted applications?

Joe is extremely knowledgeable. I trust him more than I trust my wife.

Well not really, but you get the idea....haha.

It would be interesting to see what gains can be found, if even relatively small, on an NA car with VVT tuning. Intake, headers, exhaust -- I'm sure playing with valve overlap will net at least some power, or at least I'd be really surprised if it didn't.

There's allegedly room for more lift too though, based on some old charts posted on another Z forum -- are the lift tables some of the undefined (or at least not clearly understood) tables?

Ive heard the FRS guys make some GOOD gains tuning this?

If you don't burn down the car

Any updates, Dynotronics, anyone? Has this actually been cracked, can we get more information on this? Very interested

Update: Finally had VVEL tuned on my car -- details here Proven Power Dyno Database Thread

Short version is: Definitely worth it provided you have done all the other N/A breather mods

Yep, JTran has been tuning the VVEL for sometime now! Top end gains are impressive, especially on boosted applications! UpRev has come a long ways.

Ah, but evidence of N/A gains has not been clear, at least to the best of my knowledge, until now

Or, if already known, then I offer another set of datapoints to confirm

bleunetizen · 04-07-2014, 06:36 PM

isnt the VVEL already very close to optimum (or shouldnt it be) unless you are changing the exhaust camshaft? it would be strange for nissan to put in so much effort to create this VVEL thing and have it on the market with messed up settings?

it will be interesting to see what kind of gain can be had using longer duration/high lift exhaust cams.. and make it would sound better too!

I gave up on informing the forum about VVEL tuning a long time ago. Glad you had success, numbers looked good!

UpRev has changed a lot since I started this thread years ago!

VVEL doesn't know what mods you have on your car, NA or FI, playing around with it a bit can help!
