I think the op believes that mb put a trick secret as such the key signals the ecu to improve response time. I have to say though, with the op's comment on tranny shift from 1 to 3, I'm not sure how to think about his statement in the first place.

typically id agree with this statement but the original zr1 in the 90's had a valet key and a master key that could change fuel maps. same with the newer boss mustang you can special order a "race" key that gets you more power but isnt street legal for emissions purposes. However in the case of any of the benz's the key is a key.

However reasoning behind the escalated performance with the special key was different. The keys essentially unlocked a different performance mapping. Once the engine was started, the key whether keyless or not, doesn't give any input.
Like you said, in our case, the key is a key.

C (comfort) mode always starts you off in 2nd gear... maybe you're not noticing this and assume that when it goes to 3rd gear that it went there straight from 1st gear.
just a theory

It only shifts from 1st to 3rd with the velos tune...I put factory tune back on my car and it's using 2nd again and I have that exhaust crackle often now...Idk why but my tune started to make my car run weird after about a week (someone else on this forum has the same issue)...I already contacted velos..hopefully find a solution.

doesn't the Boss 302 Mustang have key coding that unlocks some special track features? http://fordracingparts.com/trackey/
not saying the C63 does
this guy is mistaken
the car always goes 1-2-3 , sequentially
I'm not sure it's physically possible to skip a gear with this type of transmission? does it short shift in C mode?

it can skip gears but a 1-3 shift is just weird. typically your going to get like a 5-3 down shift etc....
thats strange the tune affects the shifting considering it doesnt do anything to the transmission control module, but if you tried it both ways than it must be that way.
