Why is my 0-60 so slow : (
I got 7.3 seconds! I am on auto transmission. Should i turn off all traction control completely?

you need to shift to 2nd gear to get faster speed increase after 5k rpm on 1st. Your gas is just revving the engine on 1st. Its not converting to work.

sorry for this noob question, but if I leave it in Sport Mode will it auto shift at the best moment compared if to when I put it into tiptronic mode?

I tried in both modes, and shifting manually in couple different ways, and ..... unfortunately that's what you get with a combination of an auto transmission and N52 engine.
How many miles did you put on this car? The reason I ask is because you will notice slight difference in performance after a full breakin. |

7.3 is better than what I managed with my BMS-tuned 125i

Also, was the car fully laden? How much gas was in the tank? Was there a head wind? The list could go on... Did you air down your rear tires any? What are you hoping to achieve...sub 7 second and why is it so important?

Seriously? This can read all that including HP and Torque from the cig lighter? Any one have this? Is it accurate?

How fast do you think it should be? I'm pretty sure BMW used to quote 0-60mph for the auto in 7.0, you aren't far behind. The automatic on the 128i isn't as good as the 135i. Also, are you using precise instrumentation for testing your time?
The bmwusa.com website indicates 6.1s/6.7s manual/auto. I'm pretty sure those aren't the original numbers they put out when the car was released. |
