dry nitrous tuning
well nitrous here i come. i'm finally gettin ready for my single nozzle hsw sudden impact kit.(dry) so i'll surely have some questions later on wiring it up and so fourth. this is my first nitrous set up ever. so i have hptuners and from what i understand, the timing retard can be done threw the iat with the nitrous hits. how about fuel. what all do i need to do? i currently have factory fuel system. will upgrade injectors pretty soon most likely.

Since you have tuning software, with a simple wiring modification, your IAT tables can pull timing and add fuel. If you add fuel using the IAT PE table you can place your nitrous nozzle downstream from the MAF sensor. This is much more reliable than simply spraying the MAF and expecting it to add fuel. A single nozzle after the MAF works very well to at least 150 hp.

get the harris speed works controler.
This is the only way i'd run a dry kit..

The wiring mod he is talking about is to tap into the iat sensor with a relay and resistor then tune the tables to dial in your afr. This works ok but the controler is much more accurate and easily adjusted.

I think your stock injectors may be pushing it. My car has red top 30# SVO FRPP injectors and they are usually around $100 used. But if you plan on doing a 150 shot, you may want to go bigger than that.

no it's not nessary it is pretty close with the settings but since you are swaping out the injectors and going to be messing around with the ifr tables. It wouldn't hert to get one so you could see if you are in the ball park.. I would also pull the plugs and check them out after a hard pull just to make sure you aren't lean.. Also drop the heat range at least 1 on the plugs if you are going to run 150 shot.

well i'm trying to get a full safe system together and there are way to many decisions to make. i've been lookin at the microedge progressive controller and the interface duo. Is there anything simpiler or cheaper? I'm not dead set on a progressive controller either...just keepin it as an option if i can fit it into my budget. as of right now i just have the basic hsw single nozzle dry kit. basically i need some opinions on the all in one deals that aren't like hptuners that takes years to learn how to master.

I looked and the Timing Pull write up has not been converted. If you would like to see it, the work to convert to PDF can be done today? It's a lot of bloody work, but somewhat fun none the less. Here is an example of what can be done with HP Tuner (link below), it's the Injector Scaling write-up converted to PDF. Most running the dry, and often N/A guys, will eventually need to up-size the injectors for larger N2O hits. So I put together an easy to understand and use How-To. Let me know and will gladly get to work on it.
The main reason I haven't converted this one yet is the fact that the math for figuring size has changed a little, or should I say it has been refined to allow closer estimates of HP vs Size needed. the old math was fine, but was very safe and conservative, meaning we often ended up with injectors bigger than needed.
Injector Sizing and Scaling How-To
there are ways, and many of us have done it, to tune the dry hits safely with out using the Interface. However, if one can afford it, IMO, the Interface is the way to go for tuning the Dry hits and also using the after the MAF plate.

k well that answers my injector question. looks like im gonna need some 50lb'ers. That helped alot Robert. it gave me some of the questions to ask that i didn't know how to, haha. i DO have hptuners and i'm not advanced in my tuning stages. but i really do want to learn how to. and a window switch for right now might not be a bad idea. i dont need the progressive for smaller shots. so let me try to get you to knock down some questions. what are the basics in tuning for the dry shot in hptuners? and could i get a little help trying to understand exactly how the electronics(such as microedge,progressive,interface) stuff like that hooks up with a nitrous system. i don't get the wiring part. this has already been a big help though. thanks robert

If you don't hear back just give me a PM or E-amil shout, as I usually have about 20 things going at once and often space something off, LOL.

Here you go. It took a few hours to do and fine tune, but whew, it's done. A PDF reader will be needed though. I think the Adobe version is the prefered reader.
Lets see if the crybaby crys and goes and tells on me now, LOL.

Robert, you're awsome...
I just got the same kit the OP has. I also have the Interface and Microedge though. Your site is an indespensible tool in helping the 'new to nitrous' guys like us.
I'll send you some pics and a little write-up about it when I get it all installed.
Rggbly, best of success with your project!
