My A/T Crossfire has the PERFECT relationship between my right foot and the engine at freeway speeds, but the movement of the gas pedal around town is horrible, I have to use way too much throttle. I put 3500 miles on the car since buying it earlier this summer, and I thought I would get used to it, but it still bugs me a bit.

I am thinking about buying a sprint booster to fix the issue, but I am worried that the throttle will get twitchy at freeway speeds because it will end up needing less pedal movement then as well as around town. Most of my driving is on the freeway (commute/combat driving), so this is a deal breaker for me.

Anybody have any experience with this?

 

The new sprint booster has 3 settings , personally I keep mine on red all the time and its perfect. You can switch to green so it's not so "twitchy"

 

have u tried ecu reset first? reseting the drive by wire system? might help just my 2 cents.

 

Be interested to know how this is done, is it an easy job?

 

. Get in your car

2. Turn the key to the on (not start) position, the position just before the starter
turns over.

3. Press the gas pedal to the floor with the key in the "on" position.

4. Hold the pedal to the floor for five seconds, then turn the key back
to the "off" position (don't remove the key), then release the gas
pedal.

5. Wait 2 mins. for a full alignment.

6. Drive the car as you always do.[/quote]
just got this from others ive seen talking about it on the forum i definetly noticed some difference at first in responiveness, from what i understand our cars have a drive by wire system that "learns" how we drive ive also seen some ppl on here do it regularly to reset the driving history. try it out

 

<thanks to predicessors and senior forum members> very easy job lol

 

If you always putter around, it will think that is your driving style...smart little car... If you want performance, you need to do this reset...but, it doesn't always work the first time. So, if you do the reset, and it isn't as snappy as you like, try it again...then, drive it like you stole it for awhile to learn your new driving style... If you don't, she will return to where it was before. I used to think this was huey...until I tried it many years ago....NOW, I just drive it like I stole all the time....lol

 

WOW!

Re-set made a difference!

Initial throttle tip-in and 1st 1/4 throttle response are much better.

I re-set it and drove it hard on the way home from work, I hope it lasts. At least it is easy to do again.

Thanks VERY much for the help. This and the seatbelt chime re-set (off, rural mailbox to house driveway without seatbelt chime noise) trick are very helpful.

 

Realised I have done this reset before and did notice a difference, but as you say if you always putter around it recognises that driving style.
Here in the UK our roads arent as wide as your US roads so there isnt always opportunities to put your foot down and overtake all the flat cap drivers who insist on driving 10mph under the speed limits so have no choice but to putter around so then when you do get to some open road to do some spirited driving the car doesnt recognise it, meaning doing another reset.
I think a sprint booster is the only alternative to power on tap.

On my old BMW Z4 once you did a reset and some spirited driving, that was it, the response was there even after spells of slow stop start journeys. Only ever reset it once when I first got it and needed it again in 2 years of driving.
