The Edelbrock Progressive Nitrous Controllers are used to regulate the volume of nitrous over a time period by providing a pulse width modulation to the solenoid. Additionally they calculate many conditions like seconds delay, duty cycle and gear ramps. These controllers include an LED display that has a marginally switch programming.
