I have a 2003 330i with the ZF steptronic transmission and I go between regular drive mode and sport mode often. What exactly does the sport mode do? It obviously feels more connected and sporty. I know it hold revs higher, but is there anything else aside from that? Thanks!

The ONLY thing that happens is that the program changes so that the engine revs higher before the next shift, and it downshifts quicker.

Sport Mode:

In normal driving at each and every shift (take 2 to 3 as an example) the EGS is constantly communicating with the DME and the EGS asks the DME: "Hey, I'm about to do a shift from 2 to 3. Can you do me a favor and reduce the ignition timing 10° and when I'm done I'll let you know." DME obliges and after it done, the ignition timing goes back up to normal.
This happens with each and every shift, mostly for comfort.

In sport mode, the ignition timing is not reduced. Also any pedal travel beyond 66% will have the line pressure of the transmission raised so that the shifts are slightly faster & crisper.

HTH?

It's just confusing as compared to every other automatic with a manual mode, the + and - are backwards - I've messed that up a couple of times :giggle:
The earlier steptronics (pre-2002?) had it the opposite, with + push forward to shift up and - pull back to shift down. You can actually retrofit this old style fairly easily. I think it is more intuitive.

Several writeups about this.
Want to change it?
Switch two wires.

That's what I mean, it's what I have in my 2000, it's the only car I've ever driven that has it this way which feels the wrong way round for me....

I've just discovered this, fantastic, I will be doing the mod this weekend. I can also swap the selector surround for a later model so that the + and - match up (y)

Do you need to manually upshift the box in manual mode or will it do that on its own still?

That is exactly the answer I was looking for! Thanks

Yes, you must manually shift up. Well, it might avoid going to red line and force the shift instead of explode, but the whole point of manual mode is that you get to higher revs than the automatic would do. It won't downshift unless you slow so low as to make 5th gear nonsensical. It won't start from a Stop sign in 5th, I think it goes to 2nd if you don't shift down as you slow.

Will there be any issues driving in Sport mode permanently, besides fuel economy?
I tend to drive in sport mode more than regular drive. Only thing I notice is fuel consumption. Maybe one of the gurus on here will shed some more light on possible issues. You might want to try looking on the forum, too. I remember someone asking that question a while back. 👍
