Default MS2 enhanced boost control circuit for VVT control

I want to swap mk2.5 BP-Z3 VVT engine with td04 turbo and 99 VICS manifold to my 00 NB.
I have got MS2 enhanced ecu, is it any way to control VVT with MS2 boost control output in "open loop" mode?

No, VVT control doesn't work that way

Thanks, understand. I will test it with on/off manner, later I will need to make some pwm control circuit in cooperation with my MS2 to control VVT.

Those connections are really only for MS1, which doesn't understand the NB crank and cam signals. On MS2, it's better to just put the VVTuner in parallel, sharing input sensors.
