Sport Button + Mapping???

[simonlpearce]

Just curios really how mapping an M with sport button affects the mapping process??? What happens to a mapped M when you press the button?

Been discussed a million times and there is no 'mapping' with a sport button. It controls the movement of the throttle from closed to wide open.

(aside all the other stuff on autos and changes to steering weight)

What i mean is how a remap would work with the sport button. So you take the car to a tuning specialist, stick it on a rolling road and live map it, how do mappers take into account what would happen when you then press the sport button.

Or are you saying it would act in exactly the same way. So you would have your new map, only it would continue to open the throttle sooner etc but using the new values?

I can see no way an engine remap has any effect on the closed to WOT of the pedal.

All the sport button is doing is decreasing the travel from closed to WOT. The remap does whatever it does at the various engine speeds, loads, etc.

Wouldn't affect an aftermarket map at all.

I see ok cool, was more curious than anything. So it seems the map is absolutely in no way related to the sport button, it is controlled separately.

Thanks

That's not necessarily true. I have an aftermarket remap (because I have a supercharger), and the sportbutton doesn't work anymore. Or at least: not on the throttle. It still firms up the steering.

I don't know if they deleted that part intentionally or not.

Guess that's something to do with the non m set up. Sport button on an M has no affect on the steering just the response curve of the throttle.
The variation in throttle curves between sport on/off behaves exactly the same on my mapped car as it did pre map, as said by others.

Edit... has anyone had a go at changing these curves? I find the 'normal' mode could be a little less aggressive on small throttle inputs. Believe it's a relatively simple process with the necessary programs?

 

[GuidoK]

lol the steering firming up is definately a non-m feature, but my point was that if you get an aftermarket tune, they might play with that feature (that is technically possible), so if the TS plans on getting a tune, inform first if you think it's important.

 

[TomK]

True. I've never heard of this happening but probably worth checking with whoever is doing it.

Be cool if you could press the sport button to actually activate the map. Unpressed = standard drive, economy etc, pressed = hyperspeed, 2mpg etc.

Actually, you CAN have the sport button affect your power, if you have forced induction. I'm about to go down this route. Look at the Active Autowerke Prima Plus.

What I intend to do is run a 9-10 psi pulley with my non-intercooled setup and water/meth injection. In normal, non-sport mode, the WMI is deactivated, and an electronic bypass opens to dump boost once it reaches 6 psi. With the sport button pressed, WMI is activated and the bypass is closed so I reach the full 10 psi of boost. If there is a problem with the WMI, the bypass will open to dump boost. I plan to add a second failsafe/bypass via an AEM Failsafe Wideband that monitors AFR. It's not really necessary, but I have it sitting here collecting dust, so I might as well use it.

These are all mechanical systems using the sport button a sort of a relay to tell them to activate. I don't know that it's possible to have the sport button change the actual tuning of the car with respect to spark advance and fuel trims.

You dont need FI per sé for affecting power if you're going to reroute the physical wiring of that switch.
