20.8 Time based output
This feature allows activating an auxiliary output by time, which can
be used to release the parachute, turn on the nitrous or even switch
on the torque converter lockup solenoid.

Output trigger type
Also, there are conditions, besides time, to trigger the output. The
conditions are: minimum RPM, minimum TPS, minimum driveshaft RPM
and minimum wheel speed.
All this options can be enabled or disabled. The output signal can be
an ON/OFF signal (remaining on while the conditions are valid) or a
pulse (to release the parachute, for instance), which the duration is
programmable
The available activation conditions are: minimum RPM, minimum TPS,
minimum driveshaft RPM.
If the output trigger type is ON/OFF, when one of the conditions stop
being met, the output is turned off.
When activated, the output switches to 0V. In the FTManager, select
the output in the “Sensors and calibration” menu, then “Outputs”.

Cut stage
This feature applies up
to 90% of cut to the
ignition to control
pitch or height.
20.9 Wheelie Control
This function uses the reading of height and pitch sensors to avoid the
car to wheelie. It is recommended to rear wheel drive cars and bikes.
The retard stage always retards timing when the vehicle’s front end
exceeds a predefined height. The ignition cut stage cuts the ignition
to control the front end height.
The retard stage trys to control the wheelie smoothly, in a way that
will help on the run. The cut stage is a very agressive control and the
only purpose is to avoid the driver to lose control of the car.

You can set as always active or drag racing mode. In drag racing mode,
the control will work for only 15s after 2-step.
Set the maximum height or pitch rate to activate the timing retard stage.
It is possible to use both sensors (height and pitch) at same time.
Then, enter the timing retard and the return ramp, which is a
smoothness used to avoid a sudden engine power return.
