Engine management.
The electronic engine management
system ensures optimum engine perfor -
mance at all times. It regulates all
engine-related functions and assemblies.
The results are optimum power output
and torque with comparatively low fuel
consumption and emissions. Another function is the cylinder-specific
knock control. Since engine cylinders
never all work under exactly the same
conditions, the knock control function
monitors each one separately. The igni
-
tion point is shifted individually, as and
when necessary, to protect the cylinders
and pistons at high engine speeds and loads. For compliance with EU Stand
-
ards, the on-board diagnostics detect
any faults and defects that may occur in
the exhaust and fuel systems and then
notify the driver immediately. This also
prevents increased pollutant emissions
and unnecessary fuel consumption.
SPORT button.
The SPORT but ton on the centre console
is fit ted as standard. When selected,
Sport mode is activated to provide
greater response and enhanced driving
pleasure. Throttle response becomes
even more direct, the rev-limiter is
adjusted to a harder set ting and engine dynamics are tuned for performance
driving. The auto start/stop function is
also deactivated. With the optional Porsche Doppelkupplung
(PDK) transmission, the shift points are
reconfigured are reconfigured to operate at higher engine speeds. Shift times are
reduced and gearshifts become firmer
and more immediate, while throttle-blip
downshifts are accompanied by an
emotive engine sound. Coasting mode
(p. 44) is deactivated automatically.
Auto start/stop function.
The auto start/stop function, which
is integrated as standard in the new
Boxster models, switches of f the engine
