Edelbrock Nitrous Controller - Set To Run - Nitrous Power!

Nitrous is known for its instant-on demeanor, and if you're planning to take big hits from the bottle, it used to be that only a fat set of stickies out back could get you moving from a dig. Not so much, anymore. These days, whether you're relegated to the small tires by class rules or simply chassis-clearance issues, there's a way to tame the so-called violent beast-specifically, with a progressive controller.

These controllers aren't new, and your heads-up class may or may not allow them, depending on your organization and its rules, but boy, do they work. Are they hard on the solenoids? We won't say they're easy on them, but the controller does exactly what it's supposed to do: open and close (pulsate) the solenoid to allow a preset amount of nitrous to flow at a specific rate. We will say it's important to regularly check the solenoid's plunger and seal, but for what it's worth, our radial Nova utilizes a controller, and we've yet to rebuild a single solenoid-and that's going on 13 events!

When it comes to wiring, it's nothing elaborate, and since Edelbrock includes an excellent, easy-to-follow diagram, we'll jump right into the details and show you how to program one of these little gems. To do this, we're about to disclose one of our personal tunes that enables us to hook our 1,500hp big-block on a set of 275 radials. Keep in mind, while this particular program works for us, this is only to get you familiar with the controller and its basic functions. Contingent on your chassis, every car is different, but if you've been pondering a controller for yourself, there is no denying that they work.

To recap and help illustrate the process, here's what our tune looks like on a graph. We first set the nitrous delay timer to come on 1 second from the moment we activate the unit. From there, we have the first ramp starting percentage at 40 to 70 percent for 2 seconds. For our second ramp, we set the controller to ramp in from 70 to 100 percent in 1.5 seconds. It takes 4.5 seconds for this entire process to occur. It may seem short, but there's a lot going on in that short amount of time. And should you need to abort the run, the Edelbrock controller gives you the option to reset the tune from the beginning or to continue from when you lifted your foot off the accelerator.

Nitrous delay time = 1 second
Starting rate = 40%
Final nitrous rate #1 = 70%
Nitrous build time #1 = 2 seconds
Final nitrous rate #2 = 100%
Nitrous build time #2 = 1.5 seconds
