The Maximizer 4 progressive nitrous controller operates one or two separate stages of nitrous based on either time, RPM, MPH, throttle percentage or boost pressure.
Time based progression. This option is a popular choice for drag racing applications where you always start from a dead stop. As you go down track, the controller smoothly adds more nitrous as traction increases.
RPM based progression. This option works great for vehicles that have enough traction to handle full nitrous power at the top of first gear. This mode allows you to add a little nitrous in the lower engine RPMs and ramp into full nitrous as the engine rpm increases.
MPH (Miles Per Hour) progression. This option is great for racers who sometimes begin racing from a dead stop and other times begin racing from a rolling start.
Throttle percentage progression. This option allows you to “pedal” the car in the event of wheel spin. Nitrous flow smoothly increases and decreases as you “work” the throttle, allowing you to regain traction and continue racing.
Boost based progression. This is a useful option for use on turbocharged diesels and gasoline applications. Boost progression allows nitrous to come on strong to eliminate that dreaded turbo lag but then ramps out the nitrous smoothly to let the mighty turbo do its thing.
AFR (Air Fuel Ratio) compensation and protection. The Maximizer 4 monitors the engines Air Fuel Ratio (from optional wide band O2 module), and automatically adjusts the fuel and nitrous solenoid output to achieve the desired Air Fuel Ratio (target AFR is user adjustable). As bottle pressure drops toward the end of a run, the Maximizer 4 will automatically adjust the solenoid output so you maintain a consistent and safe AFR. Air Fuel Ratio safety cut off limit (too rich and too lean) are user adjustable so the controller will completely shut off nitrous flow if the Air Fuel Ratio goes outside the user defined limits.
