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.

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

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 **** 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
