Apparently these responses are accomplished by bypassing the Uprev throttle table and directly specifying each parameter in the Ecutek software.

The first plot is the throttle opening in degrees (green), VVEL (yellow), VVT (blue) vs. throttle pedal sensor voltage in a 2000 rpm roll on. Idle is about .7 volts and full throttle is about 4.66 volts.

The second plot is the standing start data with the VVT (blue) incorporated into the same graph.

The third plot is the throttle opening in degrees (green) and VVEL (yellow) vs. throttle pedal sensor voltage in a normal standing start.

Very interesting and insightful datalog, m8!
If I interpret your data correctly, the VVT and VVL reach their final values at around 25% throttle plate position, which means that beyond this point the engine load is indeed controlled by further opening the throttle plate only, not valve lift.

I did try the map above and it seems like my low end gets a bit smoother than the modified #2, and the mid to top end are a lot better with this map 3.

If I could blend the lowend of map 2 and mid/top end response of map 3, it should have been perfect. Map 2 seems like the best blend of low end street us and highway mid to top end. Map 3 is best for G37 low end gearing, not aggressive enough for my non close gearing 5 speed A/T, but smooth low end with more oomph at the mid to top...
