Is anyone trying to unlock tuning the VVEL?

Yes. Gtm

If it does happen I'm not expecting much to justify the cost. Unless GTM sells the rights to Uprev to get a upgrade. But I doubt it.

It should make tuning more effective and efficient if they pull it off. The most profit would be made by offering it only to their customers, but I doubt Sam would take that path.

Are there any updates on the VVEL tuning? Haven't been on the boards much in the past few months...

I emailed GTM a few days ago, but have heard nothing back yet.

Thanks -- let us know if you hear something :tiphat:

That's right, I remember you mentioned that in another thread. Really looking forward to hearing what Sam tells you.

I thought GTM utilized Uprev on their 370z kits...

In for any updates.

They, but currently the Uprev software cannot alter VVEL tuning.
Sam is using a stand alone system to adjust VVEL right now to see what advantages or disadvantages it has and work backwards from that.

Be interesting to see the results positive or otherwise.

What would be the advantage of cracking VVEL?

Technical Specs & Information

Basically, lift, duration, and overlap can all be controlled on our car via tuning.

I have yet to hear from Sam at GTM just to let everyone know. If I don't hear anything from him in another week i'm going to email him again.

cool thanks for the update, and also for trying to get an answer for us. :tup:

Its still gonna be a while but..... In for updates.

/\ why you gotta be such a negative nancy??? :p

So........there is some testing going on. At least that is what one can infer from this conversation. I hope that they get it going...........

GTM is currently working on a VVEL controller that will independently control valve lift, however I'm not sure of an updated status as Sam said that they were still working on it a few months ago and has not given us an update recently.

Sam will let us know when it's going to be released. Should be a great product.

Staying tuned...

I'd be surprised if this didn't net decent gains both NA and boosted.

We could really use some more TQ

I hope this is not gonna cost an arm and a leg...

True that.... But if the gains are there people will buy it.

Do we know what kind of gains we can expect?

So I'm guessing this would something similar to the Honda's VTEC controller? Not something that will be done on a tune.+1 for need MORE TQ. LOL

Dont think there is any info of gains. Some say the gains wont be that crazy, then I hear from some that it will be like putting aftermarket cams in the car and its going to really wake the Z up.

I never heard back from GTM, I emailed them again and told them that many of us 370z owners are interested in when it might be ready, what power gains might we expect... any info that they could offer basically.

GTM is fully aware already and has talked about VVEL on the forum already a little, but they are still in the R&D phase.
If you want a quick response you need to call GTM and talk to Sam.

I swear I read on here a link to a forum in another thread where UpRev stated their working on cracking vvel as well.

You did, I need to email them again and see if I can pry some info out of them.
Cam phasing on DTB motors..

Cool, I hope the eta isn't more than a year out or so. let us know what you find out. :tup:

I have now written GTM twice but have yet to hear a single word... I told all of us on here are waiting to hear some news so maybe they will post here at some point.

:tiphat:

phone call

well yeah, but I just felt that it would be less bothersome for them to email me back when they got a chance instead of interrupting them... but I may just go ahead and call them.

want direct answers, phone call.

This doesn't always work, depending on the shop, but given that I know you have personal experience with this shop, I'd tend to agree.

I guess each experience is different. When i call or stop by I get direct answers.
