PMRobert it has nothing to do with you. Coolingmist has been here before and stirred shit up. Just preempting this time.

Id definitely like you to post progress on the thread :) but I also started the MSExtra thread so can follow there :)

I appreciate that someone with more knowledge than me is able to help/progress :)

OK, cool. As the ranking FNG here I just wanted to make sure! I'll post technical progress reports in this thread as things go. Thx, -Mike

PMrobert don't leave we need your info comeon learn us the deep dark secrets of DIY autotune ;)

Here is what I would like to do. Please find ANY thread on THIS forum where Coolingmist "stirred shit up". You will not find it. I have never been on this forum, infact I never heard of this forum until a few months ago. Never once did I start any problems here. Not my style.

Please dont post FALSE information about my company and I will gladly stay off your forum. Its obvious that you dont want any competition here and frankly I am ok with that.

You dont want my company here, I will stay off, just dont make stuff about about us.

I think this is the second, now third ban you have had from this forum

But been here before was referencing to being an asshole without a clue. Not necessarily this location/time before.

srsly? AGAIN?
FUCK.

I think I would have alot more respect for you if you can atleast admit that.

Come on man. If you're going to "sneak" back on the board, at least not be confrontational.

The first time a coolingmist employee registered on this board, he was combative and disruptive. Similar to how you are starting to act now.
That is why you were on a short leash; you are paying for the sins of your forfather.

I'm glad you guys have a HSV. I'm glad that Mike found this thread. It looks like a real, working solution is a definate possibility. I like the fact that we're only an hour away, and I'd prefer to support local business instead of sending money to England. But if your company is represented by a d-bag, then I do not want to partner with you.

Now, a lot of people on this board have Devil's Own branded WI components. So be it. As you've said, they're not your competitor anyway. Which, in a way is correct, as DO does not currently market a HSV.

I would have a lot more respect if you could act like a fucking professional.

At least his business is paying for our site :) Thanks CM,

Has anyone talked to DO about a HSV?

Alright so I found a source for valves. Im waiting to get pricing on them.

Basically 12 volt DV, normally closed SS 304/306 valve. Anyone have specs they want me to discuss with the co. when they get in touch with me.

Nice Job:bigtu:

The problem will be in the qty we might need to order.

min / max duty cycles
life (in cycles)
compatible fluids
voltage reqs
current draw
etc etc

I dont need one I was just thinkin of things to look for.

One thing I do need, is I need to know the pressure of the water, and flow we want.

pressure depends on what pump you run... probably can find that on the DO site.

I would think you'd want capacity for a few hundred cc/min at least. Maybe double what the most water volume someone will run?

The Shurflow 1000 series pumps will all do 150 psi open I believe. The pressure is alot higher going through that tiny nozzle.

yes 80-150 psi of line pressure is a good range. And the flow should be somewhere around 7-8 gph at peak then we wouldn't out pace it very quickly but if they have one that is viable from 2 gph up to 20 with good resolution that would be cool to.

good job Loki047 :)

I mean everything uses valves, they are every its just trouble finding what we need :) hopefully these aren't too expensive.

Alright the company never got back to me, but I have a few more that I am in contact with. I will retry the original one tomorrow.

Whose the most electronically advanced with HSV and how to control them? Eventually Id like to get in touch with you or put the company straight in touch with you so I don't have to go back and forth figuring out what to do.

I think that would be best WOT has a good bit of knowledge, Y8's has a aquamist unit to baseline from, and Joe seems to be a electrical genius. ;)

Well the valve itself im good with its how were are going to control it and what we need on the valve. Thats the missing key, ill call DIY later and see what they say, but they have been freakishly quiet, i assume they have something of their own in the works.

Actually, I just assumed that non involvment = 0 liability.

As far as the valve goes, ask the company if it's DC controlled or frequency controlled? See post 46.
DC controlled is going to take firmware mods to the MS.
f controlled is going to take a hardware mod.
Either way should be possible.

B

No i was planning on paying up and hopefully get DIY to write the firmware. Or ill send the valve to whoever gets the firmware running or wants to send it to me.

Where do we start with the firmware? So far all the valves ive seen are DC and not frequency controlled.

wouldn't it be easier to just find a clone of the HSV, that way no modifications (bar the WI circuit) need to be built? and it's even more useful for the whole MS community?

Did we give up entirely on the FJO valve?

I don't believe that worked without modification

Of course it would, but it would probably have to come with a driver board, which would make it cost more. I'd bet if we came up with a really affordable PWM valve, then we could get someone to write the code to make it work. I'd bet the demand would be huge.

Seems like a nice possiblity

I contacted FJO about 3 weeks ago and after an initial positive reply then then became non-commital and whilst they'll happily sell the valve seperate, wouldn't release any specs etc.

only the mods listed in the extra manual. the aquamist is specificaly stated as the valve to use

very true actually, as you were :bigtu:

http://www.fjoracing.com/products/wa...tion/parts.php

these guys list water injection valves with integral nozzle for about 130usd retail.

a friend bought one of these systems, and I tested it and found that it controlled the volume of water output from about 20-100 percent duty cycle.(like they advertised) ie at 20% duty cycle it still was able to deliver 20% flow, below that it didn't deliver any flow. At the time, their smallest nozzle was too large for my application. Spray pattern of nozzle was not as good as individual aquamist style nozzles, but not bad.

you could probably get a much better price on a group buy, and the nozzle should be easy to interface to the MS. The only issue is if they have or could build the correct nozzle size for our engine. (if you are looking for 15% water compared to fuel, and you are running 550's, then you need a nozzle that flows 330cc/min. you could then hook it directly to the MS output for wi.

the problem is we need a way to control it. There is no direct way.

Since my WI is probably a year away I haven't been hitting this as hard as I should. I'm going to try to find a way to do this without changing the firmware on the MS. Basically have an auxiliary board that is controlled by the MS to control the valve.

Can you get me specs of what you need it to do? I have something in the works that mayor may not work for you.

of course, itll take ma a day or two to get it togehter.

Devils own, I am a fuck up and completely forgot about this. I will try to get something up next week.

yeah hurry up Loki, I want injector channel PW cloned WI on my MS ;)

So, wait. Are you taking about a controller or a solenoid?

controller so we can use some standard valves

Any updates from anyone? DO?

No, ive been lazy and been mostly putting my mind towards the oil pump and some other projects. Ill come back to this in a few months. (mostly cause i suck at electrical stuff)

If all you need is for water to follow in proportion to fuel, then this is actually pretty simple. If you've got a valve picked out, then it's a no-brainer to get the electronics working. Just make WI PW = INJ1 PW when MAP > x.

Hell. Somebody wants to send me a valve with a 300cc nozzle, I'll build you a controller.

So you want a frequency controlled valve?

It's looking like the MS's WI output is sync'd to the main injector pulses. So I'd need something that'll work in the 40-125 Hz range. No good...

I've gotta figure out if there's some way for me to get either a higher-frequency PWM or an analog voltage out of the MS that rises in proportion to total fuel...

Joe, see this thread #46

Yeah, I guess I'll have to track him down on the other list and see if anything became of that.
