Well, I brought my car in to get the latest software upgrade for many reasons. They say it is a complete reflash of the software in the entire car. Programmable options are working, bluetooth a little better... I was pleasantly surprised by one aspect of the upgrade. So let me tell you the story as it happened...

So I sit down with my service assistant, and he is running me through the programming options I wanted to have changed. He also tells me that the newest software upgrade has slightly improved the engine's performance, and he has heard of cases of increased efficiency as well. As always, I am a little skeptical of this actually being true. Not believing a word he said, I just gladly took my car back and headed home.

... I have a nice night out with the SO, and on the way home. Just me and the E90. The engine is all warmed up and ready to go. Punch it.

Now I will be the first to say that its not like I have bolted on a supercharger and I am absolutely floored. I do notice a much better response in the lower RPM's. Its as if the maximum torque was now available at a lower RPM than it used to be. Understand I am not saying there is more torque... just better delivery of it earlier.

It is not a huge difference, but certainly a noticeable one if you put your foot down every once in a while. Hooray BMW... Good work :rocks:

I whole heartedly agree.... there is more torque lower now. I also have increased my fuel economy about 2 mpg, same roads, same gas and same old me driving! I am very happy with the new software, and the MP3 feature is a definite plus (finally works). Not sure what they tweaked but it is definitely a nice tweak for me doing nothing!

is this cip 19 or 20? i'll ask for this on my first oil change sometime in the summer. thanks, good to hear an improvement. how come my dash always says 25 mpg? it never moves up or down, is it accurate?

Any way to find out the version installed? Some secret button combo?

That display is your average from the last time you hit the reset button. If you hold the button down on the turn signal stock, it will reset the mpg to 0. I recommend doing everytime you top off the tank.

I just bought my car about a week ago, but I am still going to have to have a software upgrade done because my bluetooth isn't working right. I don't know how long the car was sitting at the dealership, but I doubt it was there for more than a couple weeks. It only had 50 miles on the odo so it could only have gone on 10 or 11 test drives, including mine.

No, but from your signature it looks like it was built January 2006, so it would have the latest CIP 20
