it seemed like it would be better to post this here then the FS section....
im looking to pick up a used s-hsv valve. since people seem to be wanting to swithc over to the fjo setup you can sell me your old s-hsv

what is an S-HSV? who makes it?

Thanks..

BTW the FJO valves are only like 120 each that's not much

EDIT: I figured out that S-HSV is the valve coolingmist makes, but why is the FJO better and what would make someone switch?

FJO setup injects different amounts of meth based on load and rpm. the coolingmist setup is only based on one parameter. im looking for a s-hsv because i can use a haltech output to drive it. To run the fjo solenoid valve you need to run an injector box. i dont particularly want to have more little boxes hang off all over the place.

FYI.

I would find it VERY unlikely you will find anyone switching from our S-HSV to FJO's setup. I doubt you will find a used one, but I wish you luck. We do sell a EMS version of the S-HSV. NO controller, but everything else:

We also sell the valves by themselves as well.

OUR S-HSV System can be driven based on multiple inputs, you can create a map based on as much as 8 inputs if you include our failsafe box. Without the failsafe box you can still include 2 inputs.

Currently we include things like

RPM, TPS, MAF, MAP, EGT, boost, AIR TEMP, user defined.

Lastly, we are working on an X,Y grid that will allow you to enter custom parameters to drive the valves.


Here is a vid (if you havent seen it) that has our S-HSV with our Smart Injection failsafe and flow sensor integrated.

What are the Parameters of your PWM output on your Haltech? What is the frequency and amp draw abilities?

How much flow do you need?

I am actually going to do the same thing your going to do. I am planning on using a cooling mist HSV (at this point) mainly because its between them and FJO and FJO won't return my emails and I can't get them on the phone.

Why did you come to the conclusion that the FJO solenoid must be driven by an injector driver?

0-12000 HZ up to 1 amp for an E8/E11 I believe

coolingmist

The frequency range seems fine. I would run it as high as possible, but atleast at 400 HZ. each valve will pull .25 amps, each manifold has 2 valves. You can run upto 4 valves (2 manifolds) since you can run only 1 amp..

Seems like it should work.

there was a guy on the haltech forum that said he needed to run a injector driver box to get eneough current. since i can not get ahold of fjo i can not verify this. they may have quality products but their customer service sucks. i will not deal with poor customer service, its not worth my time.

FJO emailed me back

up to 8 amps current draw WTF????

"The solenoid-nozzle assy is not designed to be driven directly from a PWM
output. Doing so will damage the unit and/or possibly your ECU. Our 341B
Engine Management system uses an external driver module [CWD0082] which you
may be able to adapt to. Average power consumption depends on the % of spray
being applied by the controller [8A max]. All components of the system are
fully compatible with 100% Methanol, 100% water, or any mix ratio thereof.
Other liquids or additives are not supported. The pump is internally
bypassed, self-regulating and only requires an inlet and outlet, no bypass
lines. It is rated for 100% duty-cycle and cannot be PWM'd without damaging
the motor.

The standalone water/meth or the 341B Engine Management systems were
designed and tested to work as a complete solution and therefore only system
specifications are published.
