Adjustment Tips - Lotus Elise Owner's Handbook Manual

• Engage first gear, apply full throttle (ECU limits engine speed
to selected launch rpm), and rapidly 'drop' clutch.
• Maintain full throttle throughout the transition from launch to
traction control (at around 6 mph) until the first gear change
is required.
• To disable launch control when variable traction control is still
required, reset launch rpm to 8,000.
WARNING: Under no circumstances should this track
feature be employed on the public road.
NOTICE:
• Do not attempt to slip the clutch during this process, as
overheating or damage to the clutch mechanism may occur.
An instant clutch engagement is required to 'break' rear tyre
traction and initiate wheelspin.
• Do not attempt LC starts in any gear other than first.
• Do not hold the engine at or near maximum rpm for more than
a few seconds.
• Use of Launch Control is an ultimate technique designed
to produce the fastest possible race start. Always allow
the clutch to cool and recover before repeating a launch
controlled start. The extreme loads associated with such
starts will result in reduced transmission component life
cycles.
• At the next key-on, the system will default to full LTC and
Launch Control off. Turning on the ignition and holding the
LTC 'off' button pressed for 2 seconds will restore the previous
traction and launch settings.

Adjustment Tips

Note that the optimum settings for variable traction and launch
control will differ for each set of track surface, tyre and ambient
conditions. A suggested adjustment logic follows:
• Set the traction control to a mid position.
• Start with a low launch rpm e.g. 4,000 rpm.
• Trial launch and assess initial wheelspin control and transition
into traction control.
• If launch control is set too low, the engine may 'bog down' and
fall out of the power band. If set too high, too much initial
wheelspin may result, with poor step off from the line.
• Similar logic applies to traction control adjustment when this
system takes over above about 6 mph.
