This may be kinda long, just trying to provide info for anyone interested in trying this, I know I coulda used it.
I run a D16Z6 with JRSC @11ps, my intake temps were getting extremely hot at WOT. When Hondata Nitrous controls first came out I saw this as an opportunity to incorporate the "poor-mans intercooler" into my setup but I had to do it quick b/c my car was getting dyno'd in 1 week by Payn Technologies, Troy MI.. Quite a drive from cincinnati and I had to be sure it was pre-wired correctly so it didn't fry my ecu up there. The Hondata website is okay but I thought it lacked a little info and I still had a few questions. I put in several calls to Hondata but no one in there tech support could help me, they said it was too new and referred me to my dealer (Payn). I got Payn to call and they pulled some strings, Derek from Hondata called me and was a big help.
If you are looking to try this, here are a few pointers and things I learned.

1. There are 2 ways to wire it, I chose to wire mine through the AC input (terminal B5) on the ECU to arm the system and the AC clutch ECU output (A15) to fire the nitrous solenoid with a relay between. There may be a way to keep your AC functional but I didn't care so I cut the wires completely at the ECU rather than tapping into them.

2. Hondata's homepage says to use your AC switch to arm the system. I tried that route first, after I got the climate controls out I noticed that there was a 14 pin connector and didn't know which wire to grab. Short on time I had to search for another option. I ended up running a toggle switch to send a ground to the ECU to arm.

3. I was previously running a NOS brand stystem utilizing 2 solenoids. Get rid of one of them, Hondata automatically adds fuel for you.

4. Make sure that your chip has the nitrous control options burnt onto it before you test the arming if it's all hooked up. If you wire it the same way I did and arm it will automatically put 12v to the solenoid and spray till you disarm (even without the program burnt on your chip).

The features are incredible, fun to play with. I may have left a few things out, feel free to ask. I still have one unanswered question maybe someone can help. Does my nitrous shut off when I push the clutch in? There is a clutch input on my datalog that does function properly, I hope they thought to utilize it.

Special thanks to Tom and Matt from Payn Technologies and Derek at Hondata.
I'll post dyno numbers later, need to get a digi camera.

 

I want to retain A/C, and I was going to run Hondata's nitrous control. Does this mean I might not be able to?

 

That stuff is cool, Tom loved tunning on it.

 

RyanCvic2000, you can use a different terminal to arm the nitrous, B8 power steering pressure, pretty sure you'll need to run a toggle switch to it like I did.

 

Tom and Matt are good guys.

Thanks. I'm getting rid of power steering anyways.

 

How do you like it so far? is it arming in every gear?

 

I love it! especially now that my whole setup is tuned, spray in any gear when I'm over 40 mph between 4000 and 7000 rpm. Don't want to blow my crappy slicks to hard off the line at the track. New tire wheel combo coming soon and I'll lower it the limiter.

 

wow..... sounds cool. Is this feature available on ALL hondata?

BTW, your rpm may rise when you turn your wheel with the nitrous controls armed. Derek from hondata told me that it will rise rpm when you turn your wheel at idle, for instance in a parking lot. It is controled by your power steering pressure switch wire. It may take the 12 v's away, unsure, but worth doing more research. Good luck.

Dunno, check out their homepage, full of all trick features, pulls timing, adds fuel, etc...

Don't take this the wrong way, I reconected the wires just didn't do a 3 way connection.

 

Maybe I missed something in the 'fine print', but here is my Q:

Lets say someone had both A/C and power steering and wanted this nitrous control. Hondata's website states that a ground is sensed on the ECU input to arm the system from either of the above two inputs. This person wishes to use the power steering input as Hondata's website also states that some re-wiring will need to be done to the A/C switch.

Well, does that mean that the actual power steering switch is what is used to arm the system? Does that also mean that the power steering switch provides a ground when not going around a turn which limits nitrous use to a straight line only? The potential downside here is what if you DON'T want to use nitrous at a given time....your going in a straight line, the parameters have been met...whats stopping Hondata from engaging the nitrous?

I realize thats probably the only time you would want to use it, however, it seems the current configuration is a bit limited. It makes more sense, to me, to use 2 switches in series with one another. One as the 'arm' switch and the other as the 'activate' switch.

I did very little research on using p/s pin at ecu to arm due to time constraints when I wired my system. I will say this though, I had a feeling if you do a 3 way connection to arm at B5 and the same thing again at A15 your a/c clutch will probably engage when you arm your nitrous. Think about it your a/c input and outputs are still wired and your sending 12v's to it. Once again, I didn't test this either, just a hunch.

 

"wow..... sounds cool. Is this feature available on ALL hondata?"

If you own an S200 system - or an S100 system, the only cost is for your dealer to set it up and tune it. Your dealer will need to download the latest cersion of the software though.

You should know the answer to this, does the nitrous control quit spraying when you push the clutch in? This is really important because I still want to use my full throttle shift option.

 

Just wondering, how big of a shot are you spraying, and are you gonna spray it on pump gas?

 

Only sprayin a 30 shot (nos jet stamped 22), we ran outta time at Payn's shop tunning, we tuned from 9 am to 4:30, g2turbo's car and my car were the only cars Tom touched all day. Unfortunately he had to be at HIN at 5:00 in Detroit. He said for a few bucks he'll burn and ship me another chip mapped for a 60 shot. I'll throw that in when I get bored. Kinda sucks that you need the rom editor to make changes to rpm/fuel/etc.. but makes sense I gues b/c the software is in your chip, not the blue box. Hell yeah I spray on pump gas! 9:1 comp, built bottom, 440's.

 

after seeing how easy it was to use it almost made me want to find a kit so i could gain another 30 to the wheels you guys with hondata that already spray really ought to get the new software and incorporate it!

to hondata for always coming up with new ideas

 

I've got a great wiring diagram if someone wants to host post it for me, sorry don't have a digi or scanner. I can fax it tomorrow at work, just gimme a fax number or pm me if you want.

 

I would like to see it, but I don't have a fax or scanner.....
