I was looking at this controller. It says you may need relays for some nitrous solenoids (ground progressive side). Does anyone know how many amps this thing is capable of? Also is there a rich afr shut down future?

 

These are a some of the things it can do.....

Two independent progressive stages of nitrous and fuel
Independent control of both nitrous and fuel duty cycle for each stage
Timer/RPM based output (+12V)
Relay output (+12V) - programmable based on any combination of: Arming input, clutch input, shift input, TPS%, AFR, Nitrous1 %, Fuel1 %, Nitrous2 %, Fuel2 %, RPM, MPH, Fuel PSI, Nitrous PSI
Relay output (Ground) - programmable based on any combination of: Arming input, clutch input, shift input, TPS%, AFR, Nitrous1 %, Fuel1 %, Nitrous2 %, Fuel2 %, RPM, MPH, Fuel PSI, Nitrous PSI
Shift light output, +12 volt
Analog voltage output, programmable - for sending to a data acquisition system or to an ECM for external fuel or spark control. Also can link to the LNC-2000 for progressive timing retard on GM LSx V8 engine vehicles
PWM output for future features - not currently enabled in the software
5 volt and ground output for Fuel Pressure and Nitrous Pressure sensors for improved signal accuracy
Arming input Ground or +12 volt selectable
Clutch input - for clutch switch or WOT switch enable input Ground or +12 volt selectable
Shift input - for gear position Ground or +12 volt selectable
Nitrous bottle pressure input, 0-5 volt
Fuel pressure input, 0-5 volt
AFR input, 0-5 volt
TPS input - accepts rising and falling voltage signal sensors, 0-5 volt
Two analog inputs - accepts rising and falling voltage clutch position sensors, 0-5 volt
Frequency input vehicle speed, possible other inputs later
Software enable/disable pull-up resistor on frequency input
Engine speed tach input
Software enable/disable pull-up resistor on tachometer input
Time based safety over-ride
Fuel pressure safety over-ride
Air fuel ratio safety over-ride
Closed loop bottle heater control using relay output and nitrous pressure input
Time based nitrous control
RPM based nitrous enable
MPH based nitrous enable
Gear position based nitrous enable
Independent Stage 1 and Stage 2 delay adjustments
User configurable between Hold & Wait or full reset when activation is removed and re-enabled. Hold & Wait resumes the progressive system at the point where the system was disabled for example, where the throttle was released
Independent Stage 1 and Stage 2 nitrous and fuel resume ramp rates
Independent Stage 1 and Stage 2 fuel advance settings that allow you to fine tune the system so that the low pressure fuel is delivered to the engine at the same time or before the high pressure nitrous, helping reduce the chances of initial lean spikes when each stage of nitrous is activated
Multiple solenoid frequency settings independent for Stage 1 & 2
PC programmable via USB interface and Windows XP, Vista or 7
No PC required - can be programmed at the unit
Saves three (3) different programs user settings on the unit
Built in display to view inputs, outputs and settings
Data logging built in PC required to read and view data. All channels logged at 100 samples second. 25 second logging time
Nitrous user settings stored in each data log for ease of recalling past nitrous settings

 

Man that sounds sweet having all those options for fine tuning.. you could set it up to hit nicely.
