F10 m5 kickdown not shifting to lowest gear possible

[hunternight5]

Hey guys just wanted to know if this is normal so I have my car in full power sport+ everything and on d3 so I was doing some testing to see if I used the kickdown it should shift to the lowest gear possible but it only shifts to 3rd between 3-4 rpm but as soon as I do that if i downshift manually it will shift to 2nd isn't the kickdown used in d mode suppose to shift to the lowest gear possible without me having to shift manually any input would be great

It would shift down to the lowest meaningful gear, I reckon.

In this instance it felt that shifting into 2nd was sub optimal for max acceleration.

Yes but isn't d3 meant for max acceleration meaning race mode

I imagine a kick down that gave you full throttle at high revs in 2nd gear would immediately trigger traction control, which would shut down power and acceleration. Selecting 3rd will give you maximum acceleration by avoiding a massive loss of traction.

Yes, that's why it didn't shift to 2nd. Max performance would be had by shifting once to third and staying there rather than shifting to second, then almost immediately again having to shift to third. Max acceleration doesn't happen at the top of the RPM band.
