Thank you Richard. Why didn't I think of that?

I have a quick a couple of questions for anyone who visit this thread, do you use it to replace running rich a/f ratio either yourself or your tuner:

1) How do you lean the fuel off?
2) How successful?

Thank you for your help. I assume that the ignition timing will take care of itself.

Can you organize a group buy for your Aquamist 2D kit?

The engine management that I use is the UTEC. I or a tuner can reduce the amont of fuel injected. There is no feedback between the 1s and the UTEC. If the Water system craps out, I'm a lean running detonating Yank.

I gained 13% in hp and torque and dropped my AFR from 10.8 to 12 while keeping the EGT the same.

When you are working with Phil in integrating with the Hydra, is there a feedback between the two?

The D2 has a clogged injector warning light, had mine come on once, a bit of the air gun back up the tip fixed that easily enough.

Question, can the clogged injector be used to warn of out of water? Not that I know of but a sensor could be installed in the tank to let you know

Gentlemen,

Before engaging on a group buy and I think you should consider your options carefully. Water injection is a tool and not an oxidant nor a fuel, it has all the ingredients to enable a “Mean and Clear” tune. Providing you or your tuner is capable (willingness) to help you achieving it.

Aquamist’s presence in the USA has been an eight-year affair, quality and reliability is consistent through out this period. The reason for not tuning with water is no longer a concern as all Aquamist system have either a in-built water fault-detection circuitry and optional add-on real-time flow monitoring device available for the basic system, they all have an output to either “switch map” or “lower boost”.

I think you should read the follow thread (url linked) very carefully. The contents in this thread and the related links are vitally important to you.
Real life facts, click here

I am happy to comment on the any part of this thread and if you feel any ambivalence on either side of the argument, please post.

I cannot organise a "group buy" from England as all sales in the US is separated from UK since 2003. Please contact any dealers listed on our "suppliers listing" section of our website. I can however give full technical support from UK as usual.

I see that PDXTuning is listed as a US retailer of Aquamist. And since they are a well respected vendor on this board I say everyone starts hassling Jeff to start up a group buy for us.

The "water fault" detection circuitry can sense clogged jet, cut pipe, bubbles in water line, no water pressure, no flow etc. It is not necessary to use a level sensor in your water tank but it will allow "early warning".

Our system2d's diagnostic circuitry compares the Duty cycle of the HSV (High Speed Valve) against the Duty cycle of the water pump. The two signals are monitored in real time and if they are out of sync, a "water fault" output is flagged (switched to ground).

The fault output can switch up to 1A and can be use to either lower boost, switch map (third party ECU) or just turn on a "warning light" as you described.

Have you tried the system with an empty tank?

Unfortunately I sold it with my last turbo system but never got paid for it I had no intention of selling it and now really regret letting myself being talked into giving it away for nothing.

Now I do remember that it can be used to lower boost, etc, I will just have to get a new unit when I have the funds, building a whole new project car is killing my budget for now!

PDX tuning has been very consistent with their view on water injection. As they have all the tools and experiences with Subaru/s.

If you didn't have an opportunity to follow the above link to "clubWRX.net", I will just make a quick summarization for you. A new water injection user took his car for a Road dyno tune has managed to loose 40+ HP. Subsequent tune has made some progress but well below par. Further discussions led him to change tuner and regained the losses plus more... Same strategy, allegedly! Doesn't seem possible?

Jeff at PDX tuning is a good choice, do go and hassle him.

Does the Utec has a on-the-fly "correction map" input so you can alter ignition or fuel or both when a "water fault" is detected?

The 1s can easily work with DDS3 and make into a "failsafe" system.

The Hydra/Aquamist integrated system has a feedback loop for sure. There are so many PWM outputs available, you can almost create a second, a third map for injecting some thing else such as Nitromethane and Methanol. Very powerful controller and totally user accessable.

Phil will annouce all when ready. I have only read about its capability on their website.

I still like to be able find a way to link up some "fail-safe switch" for Utec with the 1s. But if it is not possible, you can also use the DDS3 to lower boost.

Well the new utec revision that is soon to be released might have multiple temp correction settings. You could set a switch up that would fool the utec into triggering the highest temp correction setting if a fault was detected. This would allow you to dump fuel and drop timing.

Thank you cmj,

Is the new Utec is piggy-back system that modify the load sensor voltage for fuel and crank angle sensor for ignition? I know a range of similar type of piggyback controller such as Unichip, Xede.

When is the new Utec due out?

Its not a new utec just new firmware. The Utec is closer to a standalone then a piggy back, it fires the injectors and the ignition itself.

It was a free bump

How much did the Aquamist 2D cost when the exchange rate was normal?
I saw some old threads and it seemed they were about $500 in 2003. Today its like $850...

samwY

Thank you for the free bump.

Here is the exchange rate of British pound vs US dollar from year 2001:
(based on 2d UK price of 470.00 British Pounds)

2001 Jan x1.48 = $695.60
2002 Jan x1.44 = $676.80
2003 Jan x1.60 = $752.00
2004 Jan x1.84 = $864.80
2005 Jan x1.89 = $888.30

Lowest x1.36 (2002) = $639.20
Highest x1.93 (2005) = $907.20

Base price of the 2d have not changed since 2002. Last December, Aquamist offered a 20% discount for a short period and was snapped up pretty quickly. The discount brought the price of the 2d down to almost exactly as 2002 Jan.

You suggested a group buy earlier on this post, if you can drum up enough interest across the Forums, I think there is a good chance that a price support be repeated. It will have to be organised through a US Aquamist dealer.

How many people do we have here that are SERIOUS about buying an Aquamist 2D system.

I need a head count before I try to talk to one of the vendors.
So far I have myself, hehe.

You can still use the failsafe system with a utec. The utec has fuel and timing corrections for air intake temp and coolant temp. Just set the failsafe system up to change the coolant temp sensor resistance like Richard stated previously, and you can activate a timing and fuel adjustment.

Thank you for this information Richard. You completely put all my concerns about water injection to rest.

The only problem with a GB is which system is the most likely to be wanted. I am kind of curious which system Phil has been testing with the Hydra as that would most likely be the same that I would go with. And I would guess it is less than a 2d.

It is more than likely that Phil will go for the 2d as it fits all the criteria. It will of cause be up to him.

Richard L, what do you think the approximate install time is like for an Aquamist 2d kit? If, lets say, a turbo install was ~2 hours.
