Re: Sport Mode
Hmm... I'm not too sure if it goes faster also. but i know when i'm in Sports Drive, gear up-shift at higher revs. i'll still stay in gear 4 when i'm travelling at 100km/h instead of the normal top gear when in the normal mode. Maybe the higher RPM will give the car more pull?? Can someone clarify?

Re: Sport Mode
The effect may well be similar but momentary only. Dun forget when u set your car to sports mode, u have the option of playing with the "+" "-" of the steptronics.
I only use the formal i.e. step hard in "Drive" mode when I need to do a fast overtaking. If I want a spirited drive for an ENTIRE journey or a sustained period, it will have to be sports mode.

Re: Sport Mode
Thanks for the feedback bro's........coz i heard tat the BMW steptronics "+" "-" will spoil the gear box veri easily. And is expansive to replace the gearbox. But now I guess I dun need to worry liao, can use it veri often.
1 more question, while using the steptronics when stop complete, it only help to dwn gear to 2nd gear. So are we suppose to manually dwn it to 1st gear everytime b4 we move again???

Re: Sport Mode
I think our car by default starts off from Gear 2. So no worries. Very simple to experiment. When you car stationary, step on brake, then switch your car from D mode to SD mode, then up one gear. U shd then see from your dash that you are now in Gear 3 and not 2. That means your car goes off in 2 by default. That's why some people say Bimmers start slow. U wont have that problem when u switch to SD mode and downshift to start off at Gear 1.

Re: Sport Mode
how will sports or manual mode spoil your gearbox when in auto mode the gears are changing too?? perhaps if one is referring to running the car's engine and gearbox at a higher rpm for a slightly longer period, i believe the difference is negligable. 6500rpm is a very very conservative redline for the bmw gearbox and engine anyways.
in our normal e46 autotrans car, the sports mode only lets you hang in a lower gear for a longer period of time, as it will help you stay in the power band of the engine. the same applies for both upshifts and downshifts. pitch and yaw sensors also detect sprited mountain road driving, or slope climbing, and let you further hang in gear and not upshift even if you lift off throttle.
redline can be increased by a little right at the top, by 100-200rpm, to allow for gearchange slippages. It also increase the sensitivity of throttle stabbing, and downshifts for you more readily than normal mode.
basically, if you're not so lazy, you can do your own manual override, and change gears whenever you want. the sports mode is just a mode telling the EGS to second guess your intentions in a spirited driving mode. while the normal mode is just for you to tell the EGS to second guess your gearchange intentions in normal driving mode.
in models like the SMG or z4 or other higher end models, steering, suspension, and throttle response are enhanced in sports mode, while traction control is scaled back a little to allow some car control fun.

Re: Sport Mode
thanks guys for discussing this here... never checked out the S D mode.
tried it out last night and on the way to work this morning... it put a broader smile on my face as the E46 feels like it had 5% more torque throughout... fully expliots the good low end and mid range torque curves... now i will monitor fuel consumption as the car stays on lower gears most of the time.

Re: Sport Mode
I am not too sure. Because our ECU adpats to our driving habit, some said if you drive hard enough, the ECU will adapt and start your car from Gear 1 insteed of Gear 2. But I can't confirm this. Starting from Gear 2 is quite common on alot of auto cars nowadays. The car is less jerky that way.

Re: Sport Mode
the car will start on gear 1 if you step on it hard on takeoff. also, when you are on a slope, or if the egs adapts to your more aggressive driving.
i'm guessing why in manual mode the transmission doesnt go down all the wy to gear 1 is that there's tremendous engine brake in gear 1 and it disrupts a comfortable stop to stationary. imagine your head jerks everytime you come to a traffic light stop. it also doesnt change down to gear 1 AFTER you have stopped because it doesnt know when you'll be moving off. imagine you need to move off quickly (to prevent an accident?) but as you are throttling in to move, the ECU is downshifting to gear 1 for you. then BMW will be in for a lot of lawsuits. Therefore in maual mode it stops at 2.
my car moves off in gear 1 in normal mode, and i know this by monitoring rev vis-a-vis speed, as well as counting the gearchanges until the top gear.
depending on your gear ratios, if there's enough torque at slightly over tickover, the car can move off, be it gear 2,3,4,5 or 6. Most other car's "winter mode" (like merc) consists of a gear 1 lockout for moving off when stationary. this is so you dont do a spectacular donut burnout during winter everytime you try to move off from a traffic light stop.

Re: Sport Mode
RB your logic regarding the manual downshifting to 2nd seems logical. I would just like to add that BM engineers have thought about this problem. When you come to a stop in manual mode, your tranny down shifts to 2nd to reduce shock....etc. If you are in a situation that requires hard acceleration, you would floor the accelerator and activate the foot switch that will kick down a gear and launch you in 1st. If you are an enthusiastic driver, you will be manually shifting to 1st when the lights are about to turn green. Thus, the car cannot go wrong.
To answer the question about what gear the car starts in while in auto mode, the tranny will launch the car off on 1st unless the air temp sensor senses that the temp is
