Jigga- from fine Retailers Through luck, we have one on the shelf ready to ship today. 100% new, with all of the great features you are reading about as well. More info can be found here, click photo:



We are running a special for the month on this 1 unit, FREE SHIPPING 48 states. $939.75 would be the final price. Yes, I contributed nothing of value to this thread Actually, we have the photo from Aquamist posted (probably posted in a previous page)...that has to be worth something

i rewired my power and ground straight from the ecu where your 03 wrx diagram shows and it still has glitch problems on start up and shut off.

also do you have a diagram or can you tell me how to wire up my boost cut for my v10? i know which wire to cut from the ecu. im just confused on what 2 ports to use in teh controler box bc it looks like there is 3 to choose from.

Question regarding HFS-5:

Is there simple way to manually activate the HFS-5 to spray 100% IDC?

I would like take a short drive and steam clean the engine.


thanks.

On version 8, 8a or 9, you just need to disconnect the green wire from the fuel injector and ground it.

You can make a 2 way toggle switch:
- common = DDS3
- Normally opened = ground
- Normally closed = fuel injector
Flip the switch to ground the HFS-5 will run 100%


Version 10, use the "test" jumper link.

I have the HFS-6 kit .Richard do u have the wiring diagram for the JDM V7 EJ207 , this is the bugeye model 2001-2. Apparently I need to use 2 nozzles for water/meth injection , I am using a TurboXS FMIC where would be the best place to put the nozzles for best efficiency . Thanks .

If u dont have the diagram for the ECU , can anyone else help . Thanks

This not an easy one to find.

If all else fails, trace the fuel injection signal from the fuel injector. Subaru normally uses a pink wire with a trace of a second colour (at the ECU). You can also pick out the ignition switch wire from the fuel injection (+). It is usually yellow on the older model? The HFS-6 draws no more than 30mA on the Yellow harness.

I often think pre-TB will cause pooling as soon as the water droplet hit the throttle plate, similar to a rain hitting your windscreen.

When the jet is far away from the any object directly inline, there is a better chance of the droplet retains its surface area.

As droplet evaporates, the size will also decrease in proportion. The more time you allow this process to take place, the better the inter-cooling effect and smaller droplets. Smaller droplet (lighter) also give you better cylinder distribution. Large droplets tend to fly towards the back end of the manifold/plenum.

There is also a myth about evaporated water displaces valuable space within the linlet tract. This is not very true. Water can only continue to evaporate if the RH (relatively humidity) is below 100%. RH dedictates how much water can evaporate in a given environment, subject to pressure, temperature. Water and methanol have a specific vapour pressure that allows prediction by methematical calculation.

Vapour pressure is closely related to "Van der waals" forces, which holds the individual molecules together. Apply enough energe to the molecule, it will
break loose and separate - basic principle of evaporation. Water on the surface of a container tends to evaporate first because it has only half the "VDW" forces. Water droplet is basically the same surface water suspected in air with all surface exposed to absorb heat energy.

I know most of the water manfacturers advise the opposite, put the jet at the TB. I have yet to hear a valid arguement for this, so far none makes sense.

Did you know the HFS-6 can initiate a "limp home" mode upon a failsafe activation? It wil go to a base map and lower boost to wastegate pressure.

Here is a lnk to that thread:

There are only a handful of pins that differ between the jdm and usdm ecus (2.0L). The injector pinouts are the same. You can find the usdm pinouts on northursalia.com.

WReXd,

Thank for your help. I couldn't find any info on it so far. May be not looking into the right place.

Hi Richard,

Do you have a wiring diagram for 04 STI?
(for HFS-6)

Thanks

thanks again richard for your advice , just to make sure I have it right , u are saying don't put both meth nozzles at the Throttle body but instead preTB as far as possible before the TB .I often thought it was better to put one just post IC and the other at the TB . DO I have it right ? What have others done with good results ?

I have expressed my reasons for placing the jet as far away from the TB on post #2465. There are occasion such as TMIC where a smaller jet is placed pre IC and larger one after IC.

It will also be depending on your climate. In hotter countries where ambient temperature is high, allow more time for the droplet to perform intercooling by placing the jet as far away from the TB.

I hope others will chime in and help.

Hi Richard,

Are there any plans for a 60mm DDS3 gauge? My Defi's are 60mm and I want them to be the same size across the board.

Thanks!

No plans yet but we can machine a 60mm adaptor for you.
