Pro-Nitrous fuel tables
Here all the fuel compensation for Pro-Nitrous can be configured
according to each stage.

Pro Nitrous fuel table 8/8
On the first screen is the configuration that allows setting a delay to
start the fuel compensation, based on the time that the nitrous shot
takes to get to the combustion chamber.
After the delay, there are the fuel tables to each stage. You can program
the fuel compensation over RPM and it is calculated considering the
main fuel table.
Since the injectors are closer to the combustion chamber than the
nozzles/foggers, the purpose is that the fuel and nitrous get to the
combustion chamber at the very same time.
In the FTManager software is possible to visualize the total calculated
fuel table.
It is possible to set an OFF delay and OFF ramp after each stage. It
helps because moments after shut down the nitrous solenoid, the intake
still full of nitrous that will be consumed by the engine.

Bottle pressure compensation:
compensates the bottle
pressure drop that happens in a run. The bigger the nitrous
consumption, the bigger the pressure drops, and consequently
the nitrous mass is smaller. With this, less fuel is necessary.

Nitrous stage timing tables:
After the delay, there are the timing
tables to each stage. You can program the timing compensation
over RPM and it is calculated considering the main timing table. In
the FTManager software is possible to visualize the total calculated
ignition table.
