We're still talking about cracking VVEL. Didn't you read Steve's post, it gives you over 9 thousand horse power. :roflpuke2:

With hacking the VVL ecu I would expect around 15 hp to the wheels, not too much more or less. Which i feel would do just fine. Oh and i will do 11's all motor no slicks, going to morrow for a new tune ima have him call osrius at the same time.

So when are you gonna hit the strip for the 11's run?

do you do your own tunning?

You could always go somewhere up north, still plenty of winter left there :tup:

Its just me and my buddy who does a lot of tuning, we both bounce ideas off each other coming up with the best plan of attack. :tup:

Nice man! Am rooting for you...it will be pretty epic if this goes down

b1adesofcha0s 03-30-2011 08:52 PM

Hey jnaut, just curious, how do you think your best time would be different if you were in a 7AT rather than a 6MT? Would it be better or worse? What about a 7AT with an upgraded torque converter?

The manual take less power to opperate, so manual FTW. This is all true until a certain point and the car make too much power and you cant shift the manual fast enough. I feel the happens in the mid/high 10 sec 1/4 range and at this point automatic FTW. So in our battle/journey to the 11 on motor manual will be there first.

Cool. Good luck to you man! Make a video of your run if you can, it would be nice to see.

It never got off track, what are you talking about? :rolleyes:

haggomyeggo 03-31-2011 09:51 AM

you know what i dont get about all this cracking nonsense is why Nissan makes it so hard.

Why?
they said when the GTR was released that the ECU would be unbreakable. Yeah that lasted real long.
If someone is paying to buy your car then why should they not be allowed to change something on the car. I understand they are watching their liability but its not like once you tamper with the ECU your warranty is going to be any good anyway.
So why not let owners have the code to the ECU and let them tune away. Just make the code open source so anyone can play with it, at their own risk of course.

Jordo! 03-31-2011 10:02 AM

^^^^ I've been saying for years that TRD, Nismo, etc. should offer something like this. All they have to do is have you sign a waiver saying "off road use only", and possibly give up some warranty rights, and boom -- they'd have a thriving business in aftermarket tuning for consumers.

I have talked to the guys at Uprev, though it has been over a year, it seem Nissan does not directly write the ECU code/software. They setup what they want and someone else programs it (forget the company).

I would love for it to become open source, but it seems car companies are a bit dated on the tech/software side of things. They want to put all this awesome tech in cars but want to use horrible software or lock it down to a point even they have no clue what is going on.

Tell that to Sony... Better not hack your PS3 or Sony will sue your azz.

Which actually got me thinking.. Has any car manufacturer ever came after a shop or customer for tuning their car? Is there any legal liability tuners have to worry about if they do "crack" the VVEL setup in our cars?

I do not think so, as with Sony you are altering the actual OS to do something else, where with tuning you are just 'changing' parameters in the car which the ECU could already do itself.
Also, car manufactures can just void your warranty if they see you adjusted the ECU which is enough for them without bringing in lawyers & such.

haggomyeggo 03-31-2011 10:27 AM

for a long time i didnt get why manufacturers dont get the max out an engine. this was before you start thinking about things like reliability, safety, who they are selling it to, insurance for drivers. I think insurance is the main reason BMW has been underrating their turbo motors. I think Nissan did the same thing with the GTR. said it was 480 but werent shops getting like near 500 at the wheels stock??
I would think companies would enjoy the aftermarket to an extent. It shows people what their cars are truely capable of.

Reliability, driveability, emissions, and fuel efficiency.

A good tune will generally wind up sacrificing the last two for more power, while maintaining the first two.

:iagree:

The VVEL is the way it is to balance power and emissions/fuel efficiency I believe. To get more power you will have to compromise the other two.

i'm alrite with this! I already have test pipes so why stop here....I want as much power as i can wring out of this car

4 days ago i saw a 2012 gtr put down 487 to the wheels(100% stock) on the same mustang dyno i put down 320.

b1adesofcha0s 03-31-2011 02:39 PM

I remember hearing that one of the reasons the GT-R's power was rated at 485 bhp was due to the fact that each engine is hand made. This meant that each engine performed differently, but they all made at least 485.

Skeeterbop 10-18-2011 08:45 PM

Any updates on the vvel crack?

NewYorkJon34 10-18-2011 10:15 PM

I dont believe anyone is trying to crack the VVEL system anymore, GTM gave up, & recently I believe UpRev gave up as well. Sad day for us all :shakes head:

theDreamer 10-18-2011 10:27 PM

The last quote I got from Uprev last week:

Quote:

Everything we've tested shows there is zero gain with the stock cams. We've already built test software and we have a VVEL engine pulled apart that we're checking clearances on. So we're going to continue to build testing software for it and wait for some manufacturer to bring cams to market.

christian370z 10-19-2011 12:25 AM

That sounds like it could be a promising development! I bet a good cam could really open up the N/A tuning possibilities for the 370Z.

1slow370 10-19-2011 05:55 AM

haha they gave me that line a year ago it's all bs they don't want to stuff the time in it because we already buy their software. they sell so many licenses they don't have to care and there is no alternative

m4a1mustang 10-19-2011 06:49 AM

As cool as it would be to see some cam options available for the 370, I don't think the market is big enough to make it an attractive investment.

Yep. No chance of a significant return.

Correct. Too much time required for mild gains, and they're selling just fine without them.

I am inclined to believe you. Their conclusion was pretty unexpected...

Is GTM still working on this...? :shakes head:

Actually it would be easy for them to sell an option bit for VVEL, to those who want it, as an upgrade to what they currently offer.

I don't think you're going to get much from an NA car. VVEL allows more overlap where it makes sense (high RPM) while providing smooth streetability. It could possibly benefit FI as you don't want that overlap when you're trying to compress the AF mixture.

1slow370 10-21-2011 05:46 AM

no they've given up. it's especially bs because our exhaust cams a just a different grind on hr cams. you could probably call jwt and have a set ground for little extra cost on a set of hr cams. uprev is full of **** and just won't say it they don't care past making they're contracts to gtm and stillen work. so if it is necessary to run boost sure, uprev will do it or else they would lose contracts, thats why we got the new timing control past that we,re on our own.
