2009 135i steptronic up shifts by it self
So I though in steptronic mode you can bounce off limiter until you shift with the paddle but mine if I don't shift it automaticity up shifts for me
Also when I come to a stop it goes into gear 2 why not 1 when would you use first gear people say its best to launch in 2nd anyway? |

1st gear is practically useless with a tune but it's still fun to start in that gear sometimes. Throttle modulation becomes critical, you cant just floor it and leave your foot there. |

If I do an exhaust on my car would it sound funny when it shifts like when automatic cars have an exhaust just sounds like crap when they change gears but I no the 135s change gears pretty quick with not much lag

The ZF transmission does a nice revmatch - aftermarket exhaust sounds great when shifting.

I have and do accidentally start off in second gear from time to time but when i do I do feel a slight lag because of the missing torque from 1st gear but once i hit 5 mph that goes away. Also I know on my e89 that there is an ECS tune that automatically downshifts to 1st gear for you because of a stalling issue that is common in that vehicle. I wonder if there is a similar code push that will do the same for the 1er. |

Starting off in 2nd I assume would wear out the clutches inside the box a bit faster than normal I assume. That's why I usually make sure to put it back in first after coming to a complete stop.
Only start off in 2nd at the drag strip because like it was said above, first gear is useless when you have a tune. |

My E89 didnt downshift to 1st either. I had an ECS flash and now when i am in sport mode the tranny downshifts to 1 without a problem to prevent it from stalling when the engine is cold. |
