I have a crazy idea...

Jordo! · 03-31-2011, 09:49 PM

Just wondering, but is the VVEL ECU truly a separate unit?

If so, has anyone thought about unplugging the Nismo one and plugging it into a non-nismo Z to see if it affects output on a dyno?

Yes, a bit of a PITA... but really, if it just unplugs from a couple of connectors like any other ECU, it's really not THAT hard to test out...

Anyone feeling adventurous

I was thinking this too, it would also put to rest once and for all the debate over what contributes to the higher power output of the Nismo. BUT, I would love too see how much a Nismo VVEL ECU would cost if that shows any gains or whether you will need to retune the non-Nismo car.

Bwahahahahahahahahaha!

I just want to borrow it for a minute....

I love the idea of trying it, but I do find it hard to believe it would work without a retune, which obviously defeats the purpose.

FL 4Motion · 04-01-2011, 12:49 AM

yeah, just a minute eh??

oh btw man, got a baseline dyno done (made a thread yesterday w/all the info in the nismo section). I don't have the graphs yet but I am going to get the shop owner to email them to me. I'll get them posted up once I do.

Made pretty good numbers, more than I was expecting.

Right.

Which is why you swap it with someone who has Uprev!

This is the one factor that can't be tuned... swap the VVEL tune and what will we find?

You guys make sh!tloads more power.

Comapre and contrast...

Here, the other two have a bunch of bolt on's plus uprev tune...

Green is me (take that, Nismo!!!!) -- but it took intake, CBE, TP, AND a tune!

You guys CLEARLY have a big leg up that is not easily accounted for by just CBE, fuel and spark!

If a dynojet, would you share the drf's with me?

a better simple solution would be to have a nismo owner and datalog the VVEL during a pull 3000to red line and compare it to a normal 370z ... with Uprev , i dont know about cobb functionality

It's a great idea Jordo, I'll give you a credit for that!

but see, Its not that easy, even if its just plug in, from where we gonna find a nismo Z that are willing to trade stock VVEL with their Nismo VVEL?

I can't wait till GTM release their VVEL controller already, My credit card is waiting, waiting and waiting....

same here...even if it is just 10-15rwhp....i just hope for the love of god that its not priced above 500...that will be redicules

I think it will be little bit more than 500 but I'll be glad if its below 500!!

GTM com'n we need more power already!!

If the test car is already tuned, it would still be fair. Plus, if it really is a different VVEL tune, you should still see gains but I am not sure how much it would affect fuel trims, timing, and A/F.

Yeah, but that's less fun

Also, I don't know that anyone knows what the values mean -- but yest that would be good too!
