Modulating the nitrous hit on a 2015 Mustang with a JMS controller

Nitrous is magic. Spray this gas into your engine, add extra fuel to support it, dial in the timing and you have a recipe for an instant boost in power and torque. Of course, that torque hits hard as soon as you hit the button. That can make putting the extra oomph to the pavement a challenge.
Traditionally people wire the nitrous to a button or have it engage at wide-open throttle. Both methods have their benefits, but wouldn’t it be nice if you could have the nitrous spray when the engine is at WOT and the rpm you desire?
That’s just one of the features offered by JMS Chip & Performance’s Progressive Nitrous Controller (PN NOS-6021; $399), which is why Lethal Performance opted to augment its nitrous-equipped 2015 Mustang GT with one of these powerful units.

“The JMS Progressive Nitrous Controller is the first and only device on the market that allows for maximum adjustability and combines all of the popular add-ons in one single package. There is no need for external relays, trigger switches, or rpm switches and everything you need is built into the controller,” Brad Grissom of JMS Chip & Performance explained. “One great feature is the device does not require a laptop for programming, and all features are adjustable using a screwdriver making it perfect for quick tuning at the track or on the dyno. Other extended benefits include, adjustable solenoid frequency, built-in adjustable window switch, WOT enable trigger, dual independent ramp rates, and the universal design allows for use on 1-16 cylinder engines.”
Not only does the JMS controller determine when the nitrous engages, it offers numerous other features that will maximize the performance of your system. It will output a signal to activate a timing retard, and it can even independently control the ramp rate of the nitrous and fuel solenoids. Moreover, the controller can either turn off the nitrous or adjust the ramp rate of the solenoids in response to tire spin.
“The biggest benefit at the track is the ease of use and adjustability via the simple design, and you can immediately tune the system based on track conditions and wheel spin characteristics,” Brad added.
The Lethal Performance 2015 Mustang GT received the JMS controller to augment the Nitrous Express kit, which we covered previously. As follow-up we followed the installation of the JMS unit at Power by the Hour in Boynton Beach, Florida. The Lethal GT has since moved onto to a Whipple-supercharged combo, but if the company ever decides to run nitrous and blower, this controller will definitely come in handy.
