Around 1am in the morning here...

VQ35 VCT system is functional, I actually have a much more efficient way of running the VCT system now that references the AFM voltage at a given rpm point and with some basic data logging self learns how much PWM is required for maximum torque at the given 'cell' rpm points

Interpolatation between cells is linear.
To do this calculation, I actually set the VCT system up the same way Bikirom uses its boost control system, with the CMPOS signal looped wired up like a MAP sensor and solenoid PWM varied between ranges to keep CMPOS ref within range.

VQ30 ECU info later this week, few late nights should make some heavy progress
