HSW Interface Controller users come in! I have the HSW Interface Controller setup on my car but havn't used it yet. I got it cuz I want the ability to have N/A tuning for motor runs and want the nitrous retarded for the 150 shot when I arm the nitrous system. I havn't used it but am skeptical cuz some local guy told me he was having problems with his not being constant(not retarding timing everytime the system was armed). Has anybody had this kind of problem with their Interface????? I don't wanna risk spraying off the line(thinking it's pulling timing) and find out the hard way it didn't when I hear BOOOOM! 
I did search but found nothing regarding this.

Has he verified that its not? I've never heard of a case where it was inconsistent. You also need to remember that the Interface is in control of activating the system...if there was an issue it simply would kill the system and flash the SES light on your dash. There are plenty of users on here that have never had any issues with it...AND the nice thing about pulling timing this way versus any other controller is you can PHYSICALLY SEE the timing being pulled with a scan tool...try that with anything else on the market.

One more question Nick: Would the Interface be able to pull enough timing for a 175 or 200 shot?

My friend was having trouble with it on the dyno. It would pull timing when he armed the system just fine. But then it would pull timing even without arming the nitrous.

Yes, the nice thing about the Interface as BigDB posted above, is that you can pull an infinite amount of timing with the Interface when modifying a timing table in your tune. It won't affect your n/a timing one bit and will pull that timing once the system is activated.
Anything else, just ask. Thanks.

That was my thinking too when I started reading this. As far as I know, the interface only pulls timing when your actually activated and spraying, not when its just armed. If your car is pulling timing at times other than when your spraying, its probably something else (not the interface) thats causing it to pull timing

So what's the difference between armed and activated? My setup has a WOT switch and controled with a 3 button ashtray switch panel. Just has the arm button, purge button, and heater button. When I hit the arm button timing isn't pulled. I hope HSW is open tomorrow I'll be calling them for help.
it wont actually pull timing till u activate it. like i bought mine but have yet to get it all. hooked up im using a nos plate with the harris speedworks interface and a nos window switch. the timing wont get pulled till the window switch engages which will be 3000 rpm. i havent used it yet but will soon ill leave feedback. but i like the idea of calculated tuning vs spraying over the maf . if it works like its supposed to hats off to harris speed works it really is a great idea tho ive heard of people putting resisters into the iat sensor to pull timing but what they have done is great. i soon hope to use it to spray a 250 shot on a forged iron block ls1. only problem i forsee is that it doesnt pull enough timing i dont think on an ls1 for some reason so i may have to do somethin about that

I think if you look at the actual LEDs on the interface they show when armed and different when actually spraying. Close bottle,purge lines,and test system per kit instructions. You should see timing pulled when actually spraying.

Armed is on and ready. Activated is the kick in the *** from the nitrous your car is huffing!!! It's not going to pull timing at the flick of the switch. It's going to pull timing when it's spraying. Check again when actually spraying.
I just got back from data loging and we did have a instance where the car sprayed but did not pull timing until it shifted in to the second gear, we have also seen other sprays not pull the same amount of timing
I have opened a ticket with HSW and I will post the solution if we can find one.
oh ya i was on interface firmware 1.4
Edit The problem was that I had the wrong MAF selected. it works great now!
