Lower pricing, and 370Z support to Pro Tuners

Osiris Tuner is what you're talking about.

No cam control as of yet. Need to do a ton of testing on that, we want to make sure we give solid reliable controls on it. No point in giving people the ability to brake the VVEL system, we'd rather give safe adjustments.

Honestly the stock cam control is about flawless for NA. The torque is damn near flat off idle to redline, one of the most amazing cam setups ever built and it works so well. It may help to adjust them in boosted applications, but not till we're sure we only add safe controls.

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?

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

I have some ROMS on tap Rich....I'll give you a call....exciting news!!

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.

BMW, Toyota, and soon honda will all have continuously variable valve lift systems out in the next year. BMW had it first a year before NISSAN but the BMW system is limited by it's crappy and huge design to 6,500 RPM. The NISSAN version is good to over 8,000 and while it is still brand new the new toyota version looks to be equal to the nissan system. the new honda version I don't know to much about yet but it looks promising as well. All of these systems achieve the same basic end result with differences in max rpm, max lift, min lift, and complexity. Our system works great with good lift a large range and high rpm's but at the sacrifice of lubrication and friction. The toyota system uses a traditional camshaft but uses a special rocker shaft that his a lifter arm and pusher arm arranged like < that can change the angle between the 2 to transfer more or less of the cams motion to the valve. This only changes lift and not duration but it should be possible to replace the main cam for more power which you can't do with our VVEL. Food for thought it's out there and it's big shouldn't be more than a year or two before the american companies copy toyota again so there will be more demand for tuning these systems.

Maybe you need to dumb it down for me.

In trying to break down and decipher what you wrote, my interpretation is the lift can be changed on the Nissan VVEL. Basically duration controls where peak power will happen in the rpm range but addition lift increases peak power at that particular point. If we can increase the lift and the heads flow efficiently at the higher lift level, then peak power will increase on a assumptive basis.

It's my opinion from material read prior on head flow numbers, the 370 has some pretty killer heads.
