Any suggestions on how to do that? Brian at EFI was tuning my car for over 2 hours and couldn't figure out how to alleviate the problem.

Jordo has tons of great tips on tuning such as: "That can be fixed with tuning" and "you can tune that out"

When I had my car tuned, we were seeing some dips like that, so we added fuel to drop it down to 12.5 - 12.6 at wide open, added 2 degrees of timing and I ended up making 8whp more. I've seen a lot of the 370z and G37 tuned with UpRev and for some reason, they like extra fuel. 12.5 - 12.8 A/F seems to be making the most amount of horsepower / torque.

Yes, my tuner said that he's seen 12.8 to be the sweet spot. I remember looking at the UpRev window and seeing the fuel right st 12.8, so I'm not sure why the graph shows 13.2.

Plus, everytime I see someone say that VVEL is not going to be cracked, I remember how many thought that the R35 GTR might be untunable with all the coding Nissan built into the ECU but obviously that was blown out of the water once the aftermarket started picking up with those cars.

Exactly, now the pace might not be equal to the GT-R or other cars, but there seem to be companies willing to stick with the VQ37 and hopefully more will come.

If the DOD could be hacked, someone will find a way to crack the VVEL.

If you don't want the manifold how much would you sell it to me for?

theDreamer · 11-07-2010, 07:51 PM

VVEL is very minor, if a problem occurs it is because a physical part had more wear from the forced induction not because we could not tune VVEL. If anything, go with an aftermarket tuning ECU setup, haltech, HKS, etc.
