the crankshaft trigger on it is now like a subaru ez30, but no luck with the camshafts

[Omen234]

void initializeNissanHRvvtIn(TriggerWaveform *s) {
s->initialize(FOUR_STROKE_CAM_SENSOR, SyncEdge::RiseOnly);

int offset = 360 - 260;

s->addToothRiseFall(offset + 30);
s->addToothRiseFall(offset + 47);
s->addToothRiseFall(offset + 150);
s->addToothRiseFall(offset + 270);

s->setTriggerSynchronizationGap2(4, 6);
s->setSecondTriggerSynchronizationGap2(0.35f, 0.7f);
}


void initializeNissanHRvvtEx(TriggerWaveform *s){
s->initialize(FOUR_STROKE_CAM_SENSOR, SyncEdge::RiseOnly);

int offset = 360 - 260;

s->addToothRiseFall(offset + 30);
s->addToothRiseFall(offset + 150);
s->addToothRiseFall(offset + 270);

s->setTriggerSynchronizationGap2(4, 6);
s->setSecondTriggerSynchronizationGap2(0.35f, 0.7f);
}

The VVT is similar to the vq30, so I assumed it should be like this. but I don't understand how to implement it and verify it. explain or show, for example, dropping links to changes
