Emergency Acceleration mode SMG

davitaia · Sat, Jan-24-2009, 06:05:54 PM

I was reading SMG training reference manual and saw this.

"Emergency Acceleration
Emergency Acceleration is possible regardless of the shift mode (A-Mode or S-Mode) or
the DRIVELOGIC position engaged.
Depressing the accelerator pedal quickly to the floor without the brake pedal depressed will
engage emergency acceleration. The engine RPM will come up very quickly and the clutch
will be pulsated to ensure maximum acceleration. Wheel spin will be limited even if DSC is
switched off.
When this mode is activated subsequent shifts must be made manually."

So if you are in N and depres accelerator pedal quickly will it accelerate?
Or am I reading this wrong?

so basically this is almost like a Launch Mode?

A or S is selected with the Shift Lever by nudging it to the right or deselecting A by using the paddles.

Drivelogic program is selected by the rocker switch for S or A.

"Quickly" is rapidly, not slamming it to the floor.

No, that will only race the motor in neutral. If it would accelerate in N, people would be putting the car through walls and ramming stuff all over the place.

It is similar to a launch in that it is intended to maintain traction when dodging an emergency situation, not really designed for stoplight dragging. However if you keep your foot down when shifting to second, DSC may bog when hitting second to keep traction.

How do you engage burnout mode without engaging launch mode?

dsc off and just really mash your foot on the gas....Hard.

Translation, if you hit the kickdown switch, you engage this mode. This is why the M3 uses the gas pedal of an automatic 3'er - one nice modification is to retrofit a pedal without a kickdown switch so you don't have that annoying feel.

Acceleration boost (S6)
To activate the acceleration boost, it is necessary for the DSC to be deactivated and the S6
shift program to be active. Only with this setting is it possible to perform a "racing start".
The shift lever must now be pushed forwards and the accelerator pedal depressed. The
acceleration boost is performed once the shift lever has been released. Subsequent gear
shifts must be initiated manually.
There are two modes included in the acceleration boost S6 position. The "racing start" and
the "burnout" modes. The difference in the activation of these two modes is the rate at
which the accelerator pedal is depressed.
Depressing the accelerator slowly to the floor activates the "racing start" mode. In this
mode the clutch is pulsated at a high rate (up to 8 times a second) and the vehicle accelerates
at the fastest speed possible without spinning the tires. The wheel speeds on the
front and rear axles are compared with each other and the car pulls away according to the
clutch biting point in order to achieve optimum propulsion.
Depressing the accelerator pedal very quickly to the floor activates "burnout" mode. This
mode releases the clutch totally and completely when the shift lever is released. In this
mode the rear tires are very likely to loose traction and the rear of the car to become unstable.
Wheel speeds are ignored and the driver is in total control of wheel spin.
