Great response! Wish a few more companies (like Stillen perhaps) was more straight forward in giving an honest answer.

Watched the video of how the Variable Valve Timing works several times and still can't figure it out. However, can you control lift via programming? Shortening cam duration will increase lower end power while increasing it will pick up on top. If the factory has duration work out, how about lift? More lift will add to the top end increase. Does the system work that way?

One last one and I'm out of here......

First, have you actually tuned one and what kind of dyno do you have? Secondary, do you see the cars respond immediately? For reasons I can't figure out using the Cobb AccessPort to tune, see the air/fuel change on the dyno wideband. However, the dyno output does nothing. What's up wud dat? Makes zero sense to me. Plus the car pulls out timing on it's own and after Cobb tuning, it pulls out more mid-range timing. Can that be corrected?

I'm in Dallas so Austin is no big whoop. Being I own an AccessPort, can I make further changes (frankly no more mod plans except gears, so unlikely) using the AccessPort after you tune the car?

Think of it as a cam on a cam system, with one of those being electronically controlled.

Rich, it good meeting you in TX. Guys, Uprev was kind enough to use our 370Z while it was being tracked to test the new software. We will have the car on the dyno tomorrow and we will be in constant contact with Jarred. Not really expecting major changes but the dyno time and the tune is a small price to pay for reliability.

Great news! Does this mean there will be an updated version of cipher to download that will work with the 370z?

Thanks Rich

As many of you know this already We have been using Uprev exclusivity for our turbo kit from 350z to the G37 and now the 370Z . This product works and works well so this is good news for every one .

And stay tuned for our GTM staged power packages for our upcoming supercharger kit for the 370Z .

And let the fun begin

Sam

2 things..first is UpRev as far as houston tuners go the only reputable one I know of is EngineLogics, they have a good rep so far that I know of. Second is TT/supercharging the 370, The car already has overheating issues, fuel starvation, etc. So wouldn't that only increase those issues ? Especially when tracking the vehicle.

Enginelogics, last I talked to them (when I did my last dyno), only does Cobb. They are not doing Uprev currently, but that might have changed.
I think those issues will not increase with a better tune if tracking because they are already there even with the stock tune and will be solved with proper track prep.

The fuel issue is more than likely resolved by a larger fuel pump unless it has something to do during high g cornering. At one time had a 300-500 hp nitrous system and had to put in larger fuel lines to support it but I seriously doubt you need to go that far. The overheating issue is clasic for N/A cars converted to FI expecially in a climate like TX.

Unless something has changed, John Page of 21st Century Muscle Cars (Lingenfelter) here in Dallas will not do anymore twin turbo cars due to overheating issues. FI and increased heat comes with the territory.

Now..how about the tuning questions I asked?? Valve lift? Timing? Does UpRev even have a dyno?

Not yet, it's far simpler than it seems in that video, but there are going to be issues. First off this is a totally new thing for piston motors. The functionality of it is far more complicated than just lift, it changes the entire dynamics of the motor itself. It's not a simple as VTEC or cam adjustments. Also the way it is used by the ecu vs throttle. Nissan has millions of dollars spent on this technology and there isn't anything currently available to reference it against.

I'm sure some company will jump out there and add software controls for it, and customers will suffer with poorly running cars because of it. Or the customer will have to come out of pocket when parts of the VVEL system start failing. Thats just not how we want to do business.

So once we have a bit better understanding of what controls we can find, along with physical limits of the system (endurance testing) we'll start to create software to control it. You probably won't see anything like that for a while though. The engineers at Nissan really have gotten so much out of it so far, we're not sure of what gains may even be capable if any.
