+100000. The first few hundred miles were whiplash inducing but this technique really helped to smooth out the acceleration in normal driving conditions, but there are the times that you want some whiplash!

 

i had this too, at first. a few days after it seemed to adjust the computer and i got used to it so smoothness was not a problem.

also i have test driven 3 different bmws for comparison and they all had some pedal lag delay like i push the gas and there seems to be a dead zone b4 anything happens, i prefer something happen right away instead of delay.

 

bimmers have it because of the damn Valvetronic throttle system (no butterflies, just trick valvetrain). i think it's cool from an engineering perspective, but the execution leaves a bit to be desired.

 

Some thoughts:

Someone told me that the G automatic starts out in 1st gear rather than 2nd gear like most automatics, so there is less gear play and a more 1:1 correspondence between gas and torque/thrust.

I'm still getting jump-starts at 2500 miles. I have actually gotten honked at at lights because I am tenderly trying to feed gas to the G and its taking me too long and drivers behind me get frustrated.

My girlfriend now asks me "When are you going to learn to control the car?" This has increased my frustration level with the lurching starts.

I don't buy the explanation that it is a powerful car, so expect a lurching start. This is a powerful car for which I would expect a lurching start:

So I would absolutely love it if there was a mod/tune to reduce the pedal-displacement to thrust ratio in the first half inch of travel. Is there such a thing? I seem to spend the whole life of the car within about 3/4 inch of throttle displacement, and that includes occasionally driving like a maniac.

 

that's exactly what i am proposing.


it's not because of the gear the car starts in. most cars DO start in first. very very few start in second gear unless they have a SNOW mode.

 

that's what i experienced. if i baby the gas pedal, it moves too slow.
Then if i press the pedal 1mm further, it jerks forward.

 

i've found that with most cars (even with DBW) you press the gas linearly to go linearly. on this car, press the gas just enough to get some revs, and then HOLD the pedal in that position. the car will continue to accelerate, rather than cruise (like most cars would). wait a while before applying more throttle.

 

I do find that I have more accurate control over the rate of acceleration when I use the top of the pedal, in particular I find it is much easier to maintain consistent speed over uneven terrain.

I've never really had a problem with the speed control off the line, unless of course I'm beside a 3 series. I just wish it was a little easier for me to transition to the brake pedal from the top of the gas pedal, that would be a big help when I'm about to enter a corner.

 

i cant tell if the computer has figured out my driving style... and thus smoothed out acceleration,.. or if i'm the one who did the adjusting.

i had the lurching problem too,...but one day i just said, "screw it"... and i just went with the flow. i press the gas,... car launches forward, and i just go with it, instead of letting of the gas quickly... which causes the lurch and weight transfer.

i'm sure it doesnt help the gas mileage, but i enjoy the acceleration... and my passengers dont get suffer from nausea.

 

I just tried the "Move your heel closer to the gas pedal and use the top of the gas pedal" technique proposed here. Dang if it doesn't work, and work well. I had totally smooth control of the lower end of the throttle.

I'm now sold on this technique.

I did find it awkward to use the brake as well, until I used the technique of simply pivoting my foot over on the heel to use the brake instead of picking up and moving my foot. Worked perfectly.

And it wasn't a strain holding my foot in the new position because my shoe heel digs into the carpet firmly and allows a good pivot point on the gas pedal.

Cool!

I like the natural posture I can maintain while driving this car.

 

^ Glad it worked out for you.

 

Well, having a 6MT, its a bit of a different story.

As far as aiming at a certain rev, it definately took me a few days to get use to. But its nothing difficult; it will be second nature to you after you get use to the peddle sensitivity.

.

 

actually i found in the beginning of owning the car that if you drive in DS mode you will not get the lurch and the pedal will have more play only downside is you can get some kickdown when braking in DS depending on your speed and gear when braking, but it will give you a lot more play in the pedal im my experience. after time the D mode will adjust also.

 

Glad ot hear it worked for you!!! Getting to the brake pedal isnt too tough, I try to just pivot my foot on my heel as well, sometimes I need to reposition quickly if I think I will need a lot of brake control....

 

DS mode?
