I'm thinking of getting the mallory box to control my nitrous. To those who have used one or know, can it be used as a 2 step and window sw at the same time?

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?

If you are talking about the 685, then yes, you can use it as a window switch and a two step. That's how I use mine at least though. You just have to be careful if you plan on setting your two step above the "start" of your window switch because if you are not you will be spraying when you are sitting at the line ready to launch.

Nothing a few relays can't fix though.

I would want the 2 step limiters to be independant of the nitrous.

Besides if you have a WOT switch it still wouldnt spray until you go WOT would it?

THIS looks like the badass do it all controller:

Damn it costs though.

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.

Here's one, anyone using this?

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)

If you are using the two step you will be WOT. With a two step, with 12V applied, you will not be able to rev above a certain RPM. But, you will still be WOT. I'm not good at explaining so I'll try to word it how I use it.

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.

i would put a wot switch on the clutch petal/shifter in 1st...so when the clutch is all the way down and your in 1st the 2 step comes on

id have to thin kabout how to make sure your nitrous doesnt come on until your 2 step is off...???

Relays. I use an extra one so that way my nitrous doesn't spray until after the button is let loose.

gregrob

That or just dont go wot. I can still reach the 3500 or so rpms I'd want to leave at without going wot, just half a pedal or so

The mallory should work fine for you, no need for an expensive box. How much are you trying to spray?

gregrob

iTrader: (8)

Thanks for your input skinnies! I know you've been down this road.

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?

You can use a 5 prong relay so you can NOT spray when the 2 step is activated.

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.

gregrob

I'd agree with you there except in a M6 you already have a lot going on to be having to hold a button lol. I just want it to all work together without making it too complicated.

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

I have a full wiring diagram on how to hook up the 685 using relays for your whole nitrous system. I could scan it off for ya and email it.

That would be awesome dude! gregrob20*at*msn.com

My MSD box came with instructions on a ton of ways to wire it up. Im sure the Mallory has the same thing.

gregrob

iTrader: (8)

Ya I've read the instructions online for the Mallory but didnt see where it addressed the 2 step / nitrous window switch canundrum.

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

And I make the relay boards for the 685 that utilize the 2-Step, window switch, high speed retard function of the 685. Color coded wire and with weatherpak connectors for a plug-and-play hookup.

Would a 2-step work the same for Auto's as it would for 6-spd's? Pretty much set the 2-step to a set rpm, engage LL, pedal to the floor and let go on the last yellow? Id like to try a 2-step because a trans-brake is alittle pricey for the 4L60E.
