Mallory Hyfire Questions. 2-step?
If not I may go with a MSD 6AL-2 and nitrous outlet window sw.
I want to be able to control timing, have a 2 step, and window switch.
If the Mallory wont is there some kind of controller that will do it all?
Nothing a few relays can't fix though.

State of the art Digital Nitrous Control System allows the user to control how much and when Nitrous is delivered to the engine. This helps to prevent engine/drivetrain failure while allowing greater control in traction and performance when using your nitrous system.
- RPM Based Nitrous Control
- Time Based Nitrous Control
- RPM & Time Based Nitrous Control
- Pulse Width Modulation Control
- Ignition Timing Control
- High Speed Timing Retard
- Nitrous activation delay timer
- RPM activated switch
- Over REV Limiter
- 2 Step REV Limiter
- Fuel/N2O offset (Help to prevent backfires)
- System can be triggered from a throttle switch or a TPS sensor on EFI applications
- Will control a fuel and nitrous solenoid requiring up to 25 AMP draw
Is there anything comparable to this that is cheaper? I wouldn't mind if it didn't have the progressive feature. I already have a NOS progressive time-based controller I can use if I want to give it a progressive hit in first gear.
Only thing I see this box doesn't have is multi-gear lockout.

Accel 375+ Digital Multi-Function Ignition Module
The 375+ features a unique design that incorporates a compact control unit that can be mounted out of sight inside the car with a remote display/ input unit close at hand for real-time programming or monitioring. The 375+ Accessory control harness lugs directly into the 300+ box, allowing the custom software and dual RISC microprocessors to fully interface with each other.
Features:
- Two stages of sequential rev limiting control from 1,000 to 12,700 RPM, in 100 RPM increments
- Window RPM switch from 1,000 to 12,700 RPM, 100 RPM increments
- Fixed nitrous oxide or high-speed timing retard from 0.1 to 15.0 degrees in 0.1-degree increments
- Start timing retard from 0.1 to 15.0 degrees in 0.1-degree increments, beginning at 100 RPM, dialing out at 500 RPM
- Proportional boost timing retard from 0.1 to 4.0 degrees per PSI of boost in 0.1-degree increments (Requires the use of a MAP sensor)
- Selectable to read either 2 or 3 BAR MAP Sensor signals
- Tachometer display mode with 10 RPM resolutions and moving point-averaging software for clear resolution
- Real time manifold pressure display mode displays vacuum in inches of Hg and boost in PSI (Requires the use of a MAP sensor)

Pull up to the line. Arm the line lock and two step with a momentary switch. Pedal to the floor (WOT), then on the last yellow light, let go of the button, when I let go, nitrous sprays, line lock disengages, and two step turns off, letting the motor rev past 4800. So when you are sitting at the light, you ARE at WOT but the motor itself won't rev past whatever you have your Two step set at. But needless to say, you are still at WOT and your window switch sees that.
id have to thin kabout how to make sure your nitrous doesnt come on until your 2 step is off...???

I'm gonna run the nitrous outlet plate kit on 150 shot.
I've decided to go w the mallory box. It does everything except multi-gear lockout :-/
Now I need you guys to help me figure it out so I dont spray in first.
If it did hook, I dont think the stock 10 bolt would like it very much..
So far I'm thinking it might have to be 2 buttons on the steering wheel. One for the 2 step/line lock, and another to turn on the kit when I hit 2nd gear.
I'm also gonna set up the Mallory to pull 4deg of timing when the kit is armed. I was looking at the instructions and it looks like this is possible. Theres a input wire to activate the high speed timing retard automatically when it sees 12 volts. Just hook that to the power source for the noids.
Anyone got any better suggestions?
Yes you can set it up to pull out the timing when the nitrous is on, very easy to do.
I've seen people put a micro switch on the shifter so when in 1st it hits the switch and kicks OFF the nitrous, this is one option.
Personally I like to have the spray on a button, not just wot/window, that way I have full control of when I'm spraying.
When I get the box in hand and ready to wire it up I'll hit you up on that 5 prong relay.
I'm thinking the micro sw on the 1 position of the shifter would work. That or hook up the progressive controller and set it for like 25% in first then by the time I'm in second it would be spraying the full shot.
Probably too complicated that way though
It will be really helpful to see how his is wired up bevause its exactly what I want to do, with the exception of locking out first gear
