Linear throttle is a pretty huge difference from the stock maps.
At least on the N55, the MHD maps have tweaked the standard throttle response a bit so it's not as sharp as stock. In earlier versions of the maps before they did that it was pretty twitchy. I don't think the same guy does the N54 maps so perhaps he hasn't done the same.
Stock map - 50% pedal movement is 90% throttle. When you're used to that, linear feels pretty awkward.
I find in regular driving in D mode, it throws me off and I struggle to adjust to the extra pedal input required to make it downshift for an overtake and find I'm crawling in a high gear, then I might overcompensate and it kicks down hard. I should probably get in the habit of downshifting first.
It makes it feel sluggish in normal driving and I don't know if it's because it messes up the shift points or I'm not naturally hitting the gas hard enough to hit the shiftpoints. Maybe it's also because D mode on the DCT isn't great, feels like it's tuned for grandpa drivers.
Manual mode on the other hand, it's great, nicer throttle modulation when driving spiritedly.
I've actually been on the standard pedal map for a while but the last map update sharpened the throttle response, so maybe I'll give linear another shot. With the extra responsiveness I might adjust to it better this time.
