DBW Wizard - which pre-defined throttle do I use for Bosch 0 280 750 473

My throttle body is this model: Bosch 0 280 750 473 (heres a link to it Porsche Throttle Body - Bosch 0280750473 | FCP Euro)
But in the DBW wizard i don’t see this model available for selection. The closest one is the Bosch 0 280 750 474

Who do i go to that can help me with this?

May be unrelated but:
I am seeing weird behavior where when i initially press the throttle pedal, my AFR will go full lean (25) for a split second and then it will be fine.

This may be related to my DBW throttle body settings or enrichment settings.

I tried to attach my EMU Black project but it said new users cant post attachments.
