What makes this so hard to crack. Mike maybe you can explain to me how this all works. I know there is a seperate timing for for the valves, Is that the issue tunners are having? What would be the benefit if you do crack it.

It seems that the ECU keeps kicking back to stock timing settings. Of course tuners are stating that the settings are "so perfect" that changing them effects many other variable and thus can't be done safely. Personally, sounds like they don't want to put in the time. However, Smokey from Top Secret has the time and I believe we rewrote it from the code, but they are still developing their TT kit. All in all, first one who properly tunes timing is going to be making $$$.

This is the last response I got from Uprev, fairly clear on what they want, and hopefully in time we will see companies picking up this engine and help the process along.

It's something we'd like to do, but the reality is that no one wants to assume the liability. It's not like a typical motor set up where if you break a valve, or a rocker arm wears you just go buy that part and rebuild.

The VVEL is only available from Nissan. Nissan will only sell the matched pair of heads as a complete unit. Approximate cost is $10k, thats just the heads, no other parts.

From what we see on the earlier motors the cam phasing alone is just about perfect from the factory. You can adjust them all day and you gain 1-2hp. With the VVEL we have no less of an expectation. So realistically no one is moving forward on the development of the software because the potential gains will be very small, and the liability is huge. Also there are exactly ZERO hardware pieces in development in the aftermarket. So no replacement pieces or items that would require a change in the tuning itself.

If these factors change we'll push forward with VVEL tuning, as with everything else in the Nissan tuning market we'll be the people that develop the technology and the other manufacturers will simply copy our work.

That statement from them is very true, but there will be gains to be had for the turbocharged Z community. Spool up, primarily.
