Sport button

[elevensies]

ahh yes, your right for the Z4

Is there any difference to using the button to select sports mode to pressing the shift stick to the left on an auto or do they both do exactly the same?

they operate individually.. moving the stick over just engages manual change, you still have to press the sport button to engage sport mode

Moving it left shows "SD" in the display ie sports mode and changes at higher revs to normal mode, so I'm not sure that your answer is correct.

As said, more sensitive throttle, and reduced power steering assistance.

On an auto it also adjusts the gearbox to hold a higher gear than normal, and I think (though not 100% sure) that it changes the gear ratios too.

Bing -
It can't change gear ratios as they are fixed tooth gears. What it does do is change the up and down shift points to more aggressive settings for performance not economy.
It's actually therefore more often in a lower not higher gear.
(sorry)

Not strictly true...you can electronically alter gear ratios, we use a device in drag racing, that bolts to the rear of the transmission, its alters the gearing for street driving at the push of a button. We can go from a 5:10 final drive to a 2:30 for the foad, company called gear vendors make the unit.

is this a type of sprint booster that can be plugged into throttle or similar thing your talking about here? I've done some 1/4 mile in my Z4. Would my times be any different sports on/off?. I've got a feeling there's no actual gain as full throttle would be same with sports on/off. Your instinct is to hit the sports button straight away switch DSC off etc on the line. Next time I go will try both sports button on/off and see if there's any difference in times.

At full throttle I think I actually prefer sports button off as I'm used to that driving on the roads normally. With sports button on it can be really unsmooth sometimes but you can fel how istant the pedal is you noticed most when on full throttle then you switch sports off its like you lost about 50 horses. I notice with my rear silencer delete my exhaust really pops on down shifts too seems a lot more quiet when sports is off.

as for just pressing the sports button, it alters the throttle by altering the current across the two potentionmeters im sure. The feeling is as if you gain power but its just quickening the throttle response that's all. Automatics have gearbox ecu so this speeds up the gear changes when sports button is on. Rev limit can also be raised with ECU remap on manuals gearbox but not automatics because of the torque converter.

later bmws like E92 and others had that proper sports throttle pedal adaption were you put the key fob in and hold the rev to where you want it much better adaption. You can do throttle reset on e85's just like e46's by doing the key sequence thing key in position 1 on/off 10s wait repeat etc but I've never felt any change after

i own an auto and can assure you sport mode is not engaged when the stick is moved left, just manual change, still need to press the button for the steering and throttle response changes unless my car is different to all the other autos..it is a facelift model 3.0si

Must be different to my pre-facelift 3.0i auto as moving it to the left engages sports mode, as shown in the owners manual.

I think that the difference to using the sports button is that Drivelogic does alter the steering response but moving the lever left selects sports mode for the auto box but does not affect the steering response.

Activating Drivelogic
Press the SPORT button.
The LED lights up.
The sport program of the automatic transmission is enabled by activating the Drivelogic system. Thus, the selector lever does not have to be shifted to the left (from D to M/S).
The electric power steering switches from standard mode to sport mode. Power support is reduced for a more sporting driving style.

either mine is broke or it changed with the facelift

Must be broken as I just checked the Owner's Manual for the facelift model!

[mr.tourette]

odd...it does display sd...the steering is definately unaltered, maybe i just havent noticed the throttle response change as i rarely drive it with the stick over unless i have already engaged the sport button first...I'm sure I have drove it in maunual without pressing sport and i dont recall it feeling like sport was engaged, possibly due to the fact manually changing alters the auto experience...i will try it out tonight and report back

I don't even use the sport button in my auto, I just push the lever to the left which increases throttle response and holds gears longer.

Surely it holds them to redline? Or until you change.

knocking the gear lever to the left has always put the car into sport mode in any bmw let alone z4's. If you press the button without moving it over the car is still in sports (quicker throttle-stiffer steering) but its still in auto mode. When its across to the left the cars in sports mode and now in semi auto mode so is different. I used to 1/4 mile my E46 like this in semi-auto but its no match for manual very annoying. SMG gearbox is the way to go for proper semi-auto if u redline it bounces back and doesn't change like a manual would

can the parameter settings be changed then in NCS expert software I have tis,ncs,pa.soft,inpa etc all proper bmw software at home?

 

[Scooba_Steve]

I'd assume those can be edited, NCS Dummy can show available options if I recall. I'd love to be able to set a linear throttle in sport and a less stiffness in the wheel.

When parking at low speed I switch it back off as getting full lock to park feels like a workout or feels like I will break the steering rack. Bmw should have really just had the throttle response like it is in sport mode as a normal setting all the time in my opinion.

The heavier steering does helps on track id say at higher rpm at low its pretty useless

Get your ECU remaped is only way to curve rpm the way you want it. Jason the owner at BW chiptune actually sells the aggressive remap for M54 3.0i engines I had this on my last E46 and was day and night compared to any remaps I had before you loose 2-3mpg but worth it as this is the only map I've seen to really increase bhp/torque other sjust increase torque abit and make car feel smoother. Bw chiptune sell another switchable module if you enquire that way you can have the eco remap and aggressive remap uploaded yourself as you need it

No unless you floor it, it just holds the gear longer than usual. Pushing it left sticks it in Sport mode, only once I manually change a gear does it go into manual mode.
