The NC-1 and NC-2 units have identical features and capabilities except that the NC-2 can directly drive two nitrous stages with progressive control (modulated flow).
A progressive controller, such as the NC-2, pulse width modulates the solenoid valves and allows you to control the flow rate.
The two primary applications for a progressive controller are matching nitrous system power output to vehicle requirements and independently controlling fuel and nitrous oxide flows for optimum air/fuel ratio (AFR).
The NC-2 can be used for both applications:If you have a high horsepower nitrous system in a vehicle with limited traction, you can use time or RPM based progressive control to reduce the power output in the mid-RPM range or off the starting line to eliminate problems with wheel spin.
You can also use RPM based progressive control to reduce excessive strain on the engine in the mid-RPM range.
By independently modulating the fuel and nitrous solenoids, you can control the AFR.
This is especially useful for late model fuel injected vehicles.
Drives two nitrous stages and purge solenoid.
NC-2 is capable of 40 amp output on each stage.
Each stage is independently programmable based on throttle position, RPM, vehicle speed, time delay, and first gear lockout.
NC-2 adds capability for RPM or time based progressive control.
Output for purge solenoid (requires external relay). Programmable automatic purge when system is armed.
Flexible RPM input compatible with high voltage coil drive (vehicles with coil packs or distributor ignition), standard 12 volt tach signal, or low level logic drive (newer vehicles with coil-on-plug).
General purpose input/output (GPIO) terminal. Programmable for use as shift light output, additional stage enable input, or control output for ignition retard.
Status LED output (ideal for use with arming switch containing LED).
Built-in data logging. Ideal as basic vehicle data logger during dyno tuning or drag racing. Logs data whenever system is armed. Stores last 5 minutes of data at 10 samples/second.
Data logged includes throttle position, RPM, vehicle speed, status of all inputs and outputs, and two 0-5 volt analog inputs. If you need to add a vehicle speed sensor to a race car, refer to our Vehicle Speed Sensor Tech Note.. A separate window will open and load the pdf file.
0-5 Volt analog inputs are compatible with Daytona Sensors single or dual channel WEGO systems for logging wide-band air/fuel ratio data.
Heavy duty industrial grade clamping terminal blocks allow easy and reliable hookup without soldering or crimping.
Compact size:NC-2 is 4.1"L x 2.8"W x 1.1"H(not including mounting feet and terminal block).
USB interface to laptop PC. Powerful Windows software for programming controller and downloading logged data.
