The crank sensor on the VVTi MZFE is positioned 180 degrees from the centre of the gap in the sensor wheel (36-2) when the engine is at TDC (Top Dead Centre)

There are 17 teeth in between it and the gap.

Whether you'd enter that as 170 degrees BTDC or 180 degrees BTDC I'm not too sure.

Anyone know if this is the same on the non VVTi MZs?
