I was just wondering if anyone has figured out how to run a water injection system off of one of the PWM outputs?

Also how do you wire in a wide band O2 so that you can data log it?

Thanks in advance.

PM rxtasy1 he has that kit and a haltech, maybe he is doing that...

I have trhe AQUAMIST system 2D kit which uses an " injector " which they call the HSV ( high speed valve ) and a signal amplifier which reads and mirrors the injector signal (-ve) from the fuel computer , what I did was connect a PWM output to the amp and use the boost control map to map out the signal (which is duty cycle virsus RPM on this map ) I am not actually using it yet as I am still to tune past 15# , but it should work well , I test it by disconnecting the pressure switch (which is normally closed ) and grounding the circuit at the haltech connection point and it activates every time , remember the haltech activates stuff by grounding their control circuits .

You are in luck!
Here is a thread on what I did.

That guy named , raspyrx7 on that teamfc3s site wants to sound like he knows what he is talking about , but actually he doesn't have a clue!! , quote " the DC % goes toward zero with more boost , you want it to go towards max " , unquote.
Now correct me if I may be wrong , firstly the HALTECH E6K is a PROGRAMMABLE system , it doesn't "GO" anywhere on its own , it does what it is PROGRAMMED to do , thats why HALTECH specified in their manual that you need to increase the duty cycle on the boost control solenoid to vent off more air and raise boost , so to get more boost you HAVE to go to max on the DC% .
Secondly , what is the difference between a boost control solenoid valve and the AQUAMIST HSV apart from their uses ?, I cant think of any , they are both solenoids with high resistance coils just in different services , so why would the E6K control one and not the other ?. I think its all in the set up and the programming . The aux pump output cannot be used because the injector needs a PWM (pulse width modulated ) signal to operate , the wi pump is controlled by the inline presure switch only , the point of injection is determined by the setting of the other intake manifold pressure sensing switch only , the system is self regulating based on the setting of both switches .
When I completed the install of the system 2D , I tested it by dis-connecting the manifold pressure switch thereby simulating boost (opening the switch contacts ) and grounding the signal wire , the one which is to be connected to the injector -ve , and guess what . immediate water spray ! , since the E6K can only activate circuits by GROUNDING them through its PWM outputs , can anyone suggest why this would'nt work , isn't this the exact same way fuel injectors are triggered ? , yet "they " suggest connecting in parallel with the fuel injectors !!!.
I have 98% completed the install of my new TA51 and will soon de tuning past the water injestion point , in fact when I get hold of a laptop I will set up the boost control output to control the WI , dis-connect the pressure switch to simulate boost ) and start the engine ( the map is RPM against duty cycle) and see what happens , I am 100% sure it will activate !!!, I will be sure to let you know.
Also for those of you who dont know what are the functions of the various parts of the 2d kit , the pressure switch which is to be connected in line with the pump is to maintain the "line "pressure so that it is always "primed" , the other switch is to trigger the system based on manifold pressure and the amp. , amplifies the current to the injector since there is one power supply for the whole system thereby allowing it to operate independant of the manifold switch as the switch cannot be connected in series (connecting the pump and switch in series would be the only other way to have injection start based on boost pressure otherwise the water pump would run none stop ) with the injector 'cause the current required by the injector would fry the switch !!.

Marcel Burkett- Test it yet?

Marcel Burkett

Yeah I tested it and it did not work at all !!!!! , I still couldn't figure it out because as I said when I ground the wire that is to be connected to the injector -ve it works , so if the E6K is "pull to ground " type of activation why not ?
I noticed however , that it activates for a split second when I rev. out the engine and when I switch the engine off , any way I went ahead and set up as AQUAMIST intended and it worked flawlessly , but I am running into a problem where I am running out of gas (duty cycle @86%) , and since the HSV "mirrors " what the fuel injectors are doing ,it to is going wide open and dumping too much water in , now after I upgrade two more of my 850cc's to 1300 's as planned , I expect that problem to go away but I can now be faced with another one where things can go the other way where I have soo much gas that the duty cycles need to be a lot less and the HSV will also pulse a lot less allowing less water to flow.
After some more thaught , this is what I came up with , the E6K leaves the output off when in vacuum and switches it on at or just above 0 psi (gauge pressure), hence the reason why there was nothing when the car was idling and split second activation when switched off as the manifold pressure would go to 0 psi just before everything powers down. Can anyone verify my theory , this can be easily tested by connecting an injector or any type of solenoid valve to the output , setting up the parameters and going out and boosting a bit to see what the injector / valve would do I bet the injector would begin to pulse according to the % / rpm map when the pressure goes positive ,if anyone trys my theory out before I do please post your results . thanks.

are you using a relay on the pwm output?

MARCEL: You know its punks like you that shy people away from this forum... thus being nicknamed the evilforum... I too am looking hard into water injection with my Haltech and see exactly what raspy is talking about, I think your missing the point he is making. Maybe you shouldn't dog people before you do your research, do you even know what duty cycle is, what are your qualifications? Let this be a lesson to all of us on this forum to stop doggin each other, we all have the same interests right.......... so what is the point in talking smack... punks I hate em

rotarysc

Yes the duty cycle is adjustable, but the point he is making is that the criterion of that map aren't really conducive to how you want to control it. It does appear that it would work, but there are better ways to do it, Rxtasy and Raspy got Rxtasy's workin awesome so I have to think they know what they are doing. Wish Haltech had a water injection specific map, that based a PWM output by injector pulse and allow a DC% offset from the injector DC%

Marcel Burkett

Yeah , ******* punks like me dont like BITCHES like you either !!!!!!! .............., you wine and complain about every little thing , even if someone is trying to help you out , guys like you dont even bite the bullet and try something on your own , you just read and follow , I am not here to be your friend , I dont even know you from ADAM , so I dont give a **** about what you think about me , if the forum is to RUFF for you then dont log on ,anyone can make a mistake like your friends did , but they also mislead people into thinking what they said was true , I read the thread and the guy was WRONG !!!!!!.
For your information I know what duty cycle and frequency is , Duty cycle is how much the solenoid valve opens in percentage and the frequency is the number of oscilations per second how the HELL you think I got my car to idle properly using the BAC , if you go into the PWM set up you will see a place for the operating frequency ( or pulse as you call it ) that is adjustable up to 250 o/s , then you go to the boost control map and set the duty cycle against RPM, so for your information the wastegate control output is very capable of running the HSV ' cause as I said before and as everyone else knows it is also a SOLENOID valve . I did try out my theory , and guess what it works like a dream , what caused the problem causing me to think that it did not work is not knowing when the HALTECH would attempt to control boost by switching the PWM output and as I thougnt , I happens just as the manifold pressure goes positive .
As for your wishes about all that DC offset stuff ...........news flash ,the E6K doesn't have it ok deal with it!!!! , I am a practical person who can think HOLISTICALLY and am very quick to IMPROVISE (do you even know the meaning of those words ?) I have decided to and was sucessfull in getting the E6K to do what I want it to do by my own trial and error instead of sitting there and complaining about every little thing like if MY ***** HURT !!!! instead just following what everyone else has done I could have connected to an injector like everyone else but I wanted more 'cause I know that there would have to be more flexability with the system so that it can change with my set up if need be .
As for my qualifications .......... NONE of your F@#$in' business anyone here askyou about yours ?? , I am sure I am a whole lot more qualified than you !!!, I installed my haltech , completely upgraded fuel system ,complete and upgraded ignition , complete (more comprex than the average according to R .LAMB ) water injection system ; designed , built and installed my own custom single turbo system system on my own , all this thanks to guys like RICE , TURBOSTREETFIGHTER , ReTED , AJC13B and many others who give meaningful advice and honestly try to help , even if it means telling someone flat out that they are WRONG .

Marcel,

I have read your posts a few times... and will need to read them a few more. So you are not using the FIA2? Is that correct? I actually purchased a 2C system a while back but will just be installing it in the next month or so. I thought I understood that the only difference between the 2C and the 2D was this FIA2 box, which just reads the injector pulses... but if you are using the boost control map... then you don't need the FIA2 right?

I know I need to get the little water shock absorbers or whatever they're called, but I"m not sure I really need the FIA2... but if I do I need to get it ordered pronto!

Thanks for your help!!
