# Nitrous Control
|
|
Speeduino contains a 2 step nitrous control system for controlling valves and making fueling adjustments for dry setups.
|
|
The 2 stages operate independantly and can overlap (ie both run at the same time) if needed.

## Activation Settings
|
|
- **Nitrous Mode:** Whether 1 or 2 stages will be used
|
|
- **Arming Pin:** The Arduino Pin to be used for arming the nitrous control.
|
|
- **Arming pin polarity:** What pin state is considerd to be armed. Generally this will be LOW for a ground switching input
|
|
- **Minimum CLT:** The minimum coolant temperature that the stages will activate at
|
|
- **Minimum TPS:** The minimum TPS that the stage will activate at
|
|
- **Maximum MAP:** A protection to ensure that the nitrous will not activate above a certain level of boost
|
|
- **Leanest AFR:** Nitrous will only activate if the AFR is (And remains) below this value
|
|
|
|
## Stage Settings
|
|
|
|
The settings for each stage are identical and allow for the 2 stages to run individually or joinly overlapping during a given RPM window.
|
|
|
|
- **Nitrous output Pin:** The (Arduino) pin that will be driven high when the stage is active.
|
|
- **Minimum Engage RPM:** The RPM at which the stage will begin
|
|
- **Maximum Engage RPM:** The RPM at which the stage ends
|
|
- **Fuel adder @ Min/Max RPM:** The amount of fuel to be added at the minimum and maximum RPM points.
|
|
- The fuel adder amount will be scaled between these 2 values as the RPMs rise
|
|
- A calculator for these fuel adder values can be found at: https://bit.ly/3a0e9WU
|
|
- **Ignition retard when active:** An ignition modifier to be used to retard timing when the stage is active
|
|
- Note that the retard values are cumulative. If both stages are active then the total retard amount will be the sum of both stages. |
