Launch Mode Button
The existing left handlebar includes an unused blue push button which
MoTeC has designated for Launch Mode. Full throttle can be applied prior to
a race start to build up turbo boost, whilst limiting RPM to 2250. When the
blue button is released, full power is delivered very quickly resulting in rapid
acceleration.
The original blue button is wired through a temperature switch. This switch is
mounted in the exhaust manifold prior to the turbo and will trip at 70 °C,which
would disable the Launch Mode function. This is impractical for race
conditions.
To ensure that Launch Mode is available at all times, install a bypass plug to
short circuit the two pins of the temperature switch connector (same
connector as a Bosch injector).
