What nitrous controller?

The progressive has features that make it simple to use with a transbrake / 2 Step.
I use a time based ramp, starting nitrous percentage around 20-40%. It allows non linear ramps, 3 different pulsing frequencies and the ability to have different ramps with nitrous and fuel.... This helps when there are lean spikes on activation.
Has a 12v output I used to control my water injection system.... Allowed the water to come in once the nitrous hit a set percentage rather than once activated. It allowed the water injection to start at say 80% versus 1%. This prevents the water from taking out too much power at lower nitrous percentage.
I use the analog output to put the ramp into my RacePak datalogger, even though the unit has its own logging capabilities.
The controller can even be used to control a bottle heater with the optional pressure sensor.
The things the LPE box can do are endless.... But the biggest reason I went to it is because it is one of the only computer AND on box programmable units.

The NOS Launcher is about $200 cheaper - but it is designed for controlling the nitrous and fuel solenoids together. You can independently control them but you lose the 2 stage capability (Not a huge deal any more as its been proven 1 large kit progressed can work as well).
You cannot adjust on the fly unless you get the touch screen, which makes the Launcher more expensive. Having used both the Launcher and the NCC-002, the software differences are huge.
The NCC-002 stores 3 progressive profiles, less than 5 button presses can change between those three, this is huge for drag racing... I tend to have a killer track prep tune, a moderate tune, and a safe "just get down the track" tune in these positions....
