Programmable Progressive Nitrous Controller This topoftheline unit can be programmed to control both the amount of Nitrous that is flowed to the engine (from 0100%) and the time desired to ramp up from first hit to full flow. For example, you can program the controller to flow 25% of the Nitrous 1.5 seconds into the run and increase it to 75% Nitrous at 5.3 seconds. Or, it can go all the way to 100% much sooner. This enables a racer to fine tune the power curve of an engine to best utilize prevailing conditions. It can also be used to activate a retard box or 2nd stage of nitrous.
