VVEL control unlocked

criminalntent

If they'd work with someone who builds cams there would be no guess work involved. Creating a FI profile wouldn't put anymore stress on valvetrain parts than what is already present.

Jordo!

So long as there's no knock, no one is revving so high as to cause valve float, and there are clear safe max values to avoid piston to valve contact, at worst they'll see no gains and at best they'll see all the gains I've been hoping for.

I'm hoping they can also confirm or refute whether the Nismo ECU's have same or different VVEL target maps as compared to non-Nismo. I've been clinging to the hypothesis that they are different for ages now with no clear answers...

EDIT: nope, apparently same VVEL -- I stand corrected ECU ; stock ECU Vs Nismo ECU difference

That is a good question.

I would say they are differant b/c I had my SC kit on my sport/touring and now my Nismo and my Nismo make more power across the whole RPM range and over 35 rwhp more.

With the same dyno, gas, ambient temp. ?

Same dyno,same gas,same time of year but I noticed as soon as I started driving my Nismo I could tell it was fast right from the beginning.

I also believe the VVEL tune is the reason NISMO's have a bit more power. From what I understand the only thing you can control at the moment with VVEL tuning via UpRev is the cam timing. I've had the chance to study the VVEL with my engine builder and tuner, as my motor is being built at the moment. If we could figure out how to adjust the actual cam lobe (as the OEM ecu already does) we could really get some power out of VVEL tuning. It's very cool how the solenoid controls the cam lobe. I want to say it's somewhere around 120 degree adjustment range, less lobe to more lobe. Problem is I can only control it with my hand on the work bench at them moment :/ hopefully haltech or one of these other tuning companies can crack it soon!

Have you seen the tuning thread where EcuTek apparently has full VVEL control?

Seen the thread where they claim this, yes.

There's yet to be anything posted that proves they can control it or, more specifically, get anything out of being able to control it.

got really excited at those last few posts about nismos........ just to read 24 pages of rants, complaints, **** waving and nothing new that I didnt learn from page 1........ omg please just crack the F'ing thing. These cars have been around for 5 YEARS now. Pretty sure its a ******* lost cause by now. With nissan considering its next gen Z in a few years.....

hell in 5 years we could have trained ourselves our very own the370z.com sleeper cell to go work for nissan, had him promoted 2-3 times by now, and able to just simply tell us the secret. I mean seriously, how hard can it POSSIBLY be? maybe what you need is less gear head, and more nerd up in there. Every type of code/programing ever written regardless of their outward appearance has logical, predictable, and sensible pattern. Whether its talking with 0's and 1's, electrical pulses, P2, P2, code WHO CARES its all the ******* same principles. Im not claiming its simple. I know damn well how many complex systems the ECU is juggling, and its probably tough to find....... but holy fuckin ****, its not 5 YEARS X 3+ TUNING COMPANIES worth of hard. Im calling ******** and going to pretty much put out there that im 99% sure its a back burner priority. That they havent focused undivided attention in the least. When we get updates about something every 2 weeks to a month, and have to hear about business trips and how they "randomly" work on something it puts up a huge ******** flag that says lack of effort in giant bold red letters. I think some people are under the impression that this is being worked on by a large group of people non stop with no distractions and a large budget but its not. its probably a handful of people that randomly work on it every other week without a budget to so much as buy a god damn extra VQ engine or two to test this **** on.

Bet the NSA has already cracked it.
