I'll answer your question in Lay and then Kris can follow up with some more tech jargon
First and foremost, you're not likely missing out on much with the lack of full phase adjustment. My torque curve are smooth and consistant throughout, so don't sweat the update too much.
You have control over *when*, but not *how much* regarding the phase control (recall that phase is only on the intake cam). So if you swap cams, you can use the "when" component to better help tune your idle, etc. On forced induction cars in particular, the phasing mechanism appears to be much more fine tuning than big tuning. Again, all my dyno tuning shows that I'm not leaving much, if anything, on the table due to phase tuning...
The big power in the cam technology of our engines is found in the Lift (VVL) component. The audible notation we hear when the car is "on the cams" is the lift change (not phase or VVT). You have complete control over lift. It's both load and RPM based. Both cams change lift together.
All cam adjustments are made in the VANOS section of the software. I gather that EFI chose the term VANOS to describe the cam section of the software since BMW is their primary audience. Think of the VANOS tab as being the VVTL-i tab for all intents and purposes...
I think you're going to really "dig" the system.
A note about mods you should also do. Dump your stock intake system during the install!
There's good power and torque to be found with an aftermarket intake. Dave is running the Reverie intake I believe and makes great power. Jim made a nice homemade unit, as did I. If you need help with one, let me know. You should use a bigger inlet since there's no MAF to worry about anymore.
I have maps coming out my ears that you're welcome to use, as do the other guys.
Finally, you're going to have to drill and tap a hole in your intake manifold for the IAT. Dave and I did this with the greasey drill bit and tap method and it worked great. I sugges you do the same to save some work. Just go very slow and use plenty of grease. Took about 15 minutes to drill and tap the hole which beat the heck out of pulling the intake off...
Best,
Phil

I spent time to read the tips and also the link provided by Kris, interesting. At the moment, I am waiting for the EFI, should be shipped this week. I spend time also to play with the software supplied on EFI website.
In regards of the VANOS control, it is not clear for me. OK, the software I am using to learn is probably not the same than provided in the kit, and the VANOS constant are not the same, it is not VVL control available, but VVT control. As per your tips and information, the program provided for the Lotus is able to adjust the VVL, but not the VVT. On KRIS note, it is said that the table is on progress. On Turbophil, it is said that whatever you have the impression to adjust something, nothing have effect (something like that).
Now the question, if the software is not able to adjust the VVT, how it is managed?
Is it an internal code on the program, not managed by the software, but accessible for EFI programmer?
Since I am not a programmer, is it possible to imagine to play with that? When the software will be available to manage that, any date available? next winter, next summer, next year???
Regards
