In case you disconnect the Selector switch from
the Sprint Booster, the device will keep the last
settings in memory. (e.g if you disconnect the
device while you are in SPORT-5 the device will
work as SPORT-5).
As soon as you turn off your car's engine the
switch (led indicator and led display) will remain
active for a few minutes and will go Off as soon
as the CAN bus system cuts off the electric
power supply. This is a normal procedure and
will not drain your battery.
