The Progressive fuel table by nitrous duty cycle and the Auxiliary fuel
enrichment table compensation are related to the percentage of fuel
added according to %DC of nitrous or engine load/rpm.
After the end of nitrous shot, normally is necessary to keep the
compensations on for a few tenths of seconds, since the intake is full
of nitrous that will be consumed by the engine. The OFF ramp makes
the compensation ends smoothly.
The delay to start the timing compensation has the same purpose of
fuel compensation, the time nitrous takes to reach the cylinder.
The Progressive timing table by nitrous duty cycle and Auxiliary timing
retard compensation are related to the timing retard (always negative
values) according to the %DC of nitrous and engine load/rpm.

In the end, there are the OFF delay and the OFF ramp and are used
to keep the engine safe, avoiding an immediate timing advance that
could damage the engine.
19.11 Boost control
This feature allows the control, through PWM, of a solenoid valve that
manages the wastegate valve, therefore regulating the boost pressure.
Through an external button, you can activate the Boost+ function
(optional use), which is an instant increase in the boost %DC while
the buuton is turned on.
FuelTech recommends using a 3-way button N75 solenoid.
For more information about its installation, see chapter 13.8 in this
manual.
The first parameter is the output which will drive de boost solenoid.
Select among the available outputs. After this, select the Boost+ input,
in case of needing.
In the FTManager, this setting is done in the “Sensors and calibration”,
then “Inputs” and “Outputs”.
