As you can see from this graph:

It seems correct that on the low cam there is no diference between 0 or 10 vvt value

But in the other hand there is a diference from 0 to 10 on the vvt setting once on the big cam, in power at least

I don't see anything indicating which run is which setting?

Either way it does not matter, look at my oscope readings and you will see (you can measure it yourself visually) 0, 5 or 10 or anything in between does not affect the offset in degrees, neither does anything above 50.

first graph only low cam, second only high cam,

And yes that good info from the oscope, but as you can see from the graph
now the why i honestly dont know
