Default Throttle questions

1) When not in sport mode, on an SMG, does the kickdown switch at the bottom of the gas pedal actually give more throttle? i.e. do you have to push the switch for 100% WOT.

2) Can anyone actually drive with sport mode? I feel like it's so jerky. At the track, the slightest press would upset the car.

I can answer #2.

I donít use sport mode. I can apply throttle smoothly with sport mode but it takes a lot more mental focus.

Might be a good early learning tool for smooth throttle application.

I drive with Sport mode only after the car has warmed up, and only on the highway because of the jerkyness/kangaroo'ing at low speeds.

As for the "kickdown switch", I believe it does allow for full throttle.

When engine is cold...I use to kangaroo but I learned how to modulate the throttle that I don't anymore. Try using it when there's no one around so you don't look stupid when you do. Eventually, like bigjae1976 said...you'll learn.

Default Re: Throttle questions

In sport mode the kick-down doesn't do anything except confirm for you that you're at WOT. I've had my torque app hooked up during driving, and the pedal is at WOT even before you're at the kick-down (pedal still has room, then you hit the kick-down button).

It's more useful if you drive in Auto mode, especially road trips. If you want to immediately downshift to the lowest logical gear and be at full power, like when moving into a passing lane, you can just stomp to the kick-down and it will downshift and go.

You can modify the Comfort and Sport throttle maps using Martyn's Tool. I had the same issues and was able to completely customize the throttle sensitivity. Works great now!
