@visconti or Rich, were any VVEL adjustments made or is VVEL still on the back burner?

At this point, we have control over VVEL but there haven't been any significant gains to be had with our NA tune. We think forced induction applications will make more use of VVEL adjustments and we'll continue to research. We have however made gains with VVT in this calibration. There is also room left to grow with this calibration and we intend to continue updating the tune as new advancements are made. And of course, anyone purchasing this tune will have first crack at all of these new revisions.

Adding more or less overlap or something?

I know you won't tell me what you changed (even though I have UpRev and therefore couldn't copy you anyway), but can you tell me where in the RPM range you got gains by fiddling with VVT?

Thanks!

Mostly in the mid range.

When we have your datalogs we can make any necessary adjustments to fine tune the calibration for your car.

We also have an extensive guide included that will walk you through the entire process! It really is a very easy upgrade, especially after you become familiar with the software! We're really happy with it!

So from the time you initially flash the car, till you have the data to correct the tune and sent the update, the car will not be 100% and people should hold off on any sort of spirited activity right??

So for the N/A guys (the larger margin of 370Z owners right now), there are no real "gains" to be had from VVEL tuning, which was supposed to be one of the major selling points for the ECUTek software?

My understanding regarding VVEL tuning was always that it probably wouldn't be much use for N/A application (which is one of the reasons we didn't screw with it on my car). The real potential is to see what it can do for FI applications. However, it doesn't look like anyone is diving head first into that one... not that I blame them.

I'm hoping they do, because it would be really cool (not just for the added power) to see what it is that makes it so complicated...

I'm a huge nerd so that stuff interests me on the How/Why things are the way they are. Why has it taken people going on 4 years to crack it, when everything else was done seemingly the next day (Cobb/UpRev in 09-10).

Can't blame them neither. The money adds up quickly

Probably correct ... but I think if you change out the stock intake manifold with something that sucks more air volume in than the stock one does on an NA platform ... seems that would be potentially gains with ecutek. I could be wrong ... I am no rocket scientist when it comes to this stuff.

We do anticipate starting our Forced Induction development very soon. In the meantime though, there are some very nice gains to be had with our calibration and basic bolt-ons

This car is another new frontier for EcuTek, but based on the advances and improvements made with EcuTek on the GT-R platform, you guys should be in for some exciting stuff!
