The sounds of a DBW Throttle Body

Thought my throttle body made noises and decided to try to get it on “tape”
Turned out very proffessional.

Is it normal or is there something funny going on ?

which noise you referring too, the high pitched one?

Yes.

And I felt that it was mowing in rather big steps.

pretty sure the high pitched noise is normal as the motor is a high speed h-bridge so it’s probably just the switching frequency

Steps wise I’d not know, but I doubt there are that many sites in the map, 32 at most.
