6C cruise control vs my right foot

[2226]

Something I've always found strange with this car since shortly after I bought it is that it pulls much harder using the cruise control as opposed to me mashing the go pedal.

For example, enable cruise control, don't engage it, get up to 100km/h in 6th and then engage cruise control.
Then hit the + on the wheel and ask for 120km/h or more and this little 1.2tsi will shove the seat into your back.

Disengage cruise control, back down to 100km/h, then mash the pedal to the floor.
Nothing. Just a slow uneventful climb up in speed.

I just did a short trip across the neighbourhood and I thought I'd see whether it does it at much lower speeds. And sure as all heck once it gets beyond 3000rpm it goes like crazy. Switch to right foot control and do the same thing and it's all subdued.

What is it doing to get better pull under cruise control?
Surely it can't just be throttle control?

Does VW just not trust me?

Or am I just imagining things once my foot is off the pedal (i.e someone else is driving).

I honestly think it's just VW mapping their throttle pedal for more fuel efficiency like in this very sophisticated graph I made

As opposed to the CC which is in my mind a straight line

This is me just guessing tbh and it could be something completely different.

I did the adaptation to the linear throttle instead of the time delayed setting. I think this smoothed out that annoying stumble I often have when pulling away, but otherwise nothing else feels different. This might be me just driving different today though as I don't think that setting actually relates to pedal input.

I think you are correct in how it is mapped (pedal input vs throttle opening), but the pedal input in this case is at maximum (foot to floor).
Would interesting to find out if it can be altered. Maybe it gets done with some remaps.

I guess one's age starts showing when you still prefer a cable/rod throttle connection.

What adaptation are you talking about? You made me curious about it

[2226]

Just the adaptation many say has improved throttle response, but I honestly doubt that is what they say it is.
When you look into it it's in the steering control module listed as driving profile switchover.
Many have said this improves throttle response because the options are either for time delayed or direct.
I'm sure this is only applicable to vehicles that have different driving profiles and some intelligence on which one is selected. It's probably only there to smooth things out in the switch over or prevent accidental toggles of the driving mode switch, etc.
The only way I can see this actually affecting pedal-throttle mapping is if some ECU calls for a driving mode switch then it happens sooner and therefore maybe the throttle switches some response profile sooner.

I toggled it, then toggled it back off, since in this car there is no driving profile options anyway so a pointless thing.

"Normal" adaption would be where you change/clean the throttle body or if the pedal box is renewed, even the older cable throttle required throttle body adaption as the idling was motor controlled (only), if you cleaned the throttle body it would adapt itself after a bit of driving. (but not the above referenced).
