Why is there no Bosch 82mm throttle in the firmware?  
Part number 0280750473  
I have this throttle, but dbw wizard lists 0280750474 which is 74mm.

Is dbw working correctly because of this?

Probably use that, and then do the auto calibration. I used an NC MX-5 throttle body without any presets, also works perfectly fine after auto calibration.
