Aquamist HFS-5 poblem...

2fas4utoo! · Jan 13, 2009, 09:42 AM

Currently I've install in the HFS-5 on my car, and it was set up using injector pulse. It work fine. Then we decided to switch to set it up by boost signal and I can see it activates but it doesn't seem to be flowing. Currently it activates 16.5 psi. Any help its appreciated.

What version DDS3?

Also when you say you "set it up for boost" please elaborate. List EVERYTHING you changed and I should be able to help you figure out what went wrong.

Also what do you mean by activate, please describe what is and what is not turning on.

Yes, the newest version DSS3,

Instead of reading iinjector pulse, I disconnected the cable from the injector signal and ran the cable to the map sensor.

When I mean activate, since this an Evo X it has 3 bar map sensor it activates the system when it hits 16.5psi (it turns the red light on the small box and at the end of the bars on the DSS3 it turns on I believe a red B letter)

But the flow bars on the DSS3 dont turn on and the pump doesn't seem to be turning on. When I ran the test the bars moved until 4 bars more or less and the pump seemed loud (this may be since the car was not rev) the system injected methanol cause the car had trouble starting up.

Thanks a lot in advance dudical26!

When you say the most recent versin of the DDS3 - this is version 10. Is that what you have? If so you should not be disconnecting any wires, only moving a jumper over.

You need to move the jumper AND it needs a map voltage signal.

I previously had the wire connected to the injector signal cable. Sowhat I did is connected to map voltage signal cable. I believe I was correct cause the system is activating when boosts hits 16.5PSI.

That what I did connected to the map voltage signal, What I need to do then is move the jumper? Just do trial and error?

The v10 has individual input for MAP sensor and PWM. When you want to change over, just relocate the jumper link.

You can leave the fuel injector wire in place. Just run a separate wire from the MAP sensor to the appropriate DDS3v10 input (MPS IN)

I have asked you a bunch of times....what version DDS3 do you have? It says it on the junctin box. It makes a difference as to what needs to be done.

Also - trial and error is really not a good idea with the advanced electronics in the DDS3. You can easily burn out the board by connecting the wrong wire in the wrong place.

The instructions included with your kit cover this situation so please do read them. I am happy to help you sort out your goal but we need a little more info and a bit of patience on your end.

Please don't just go connecting wires if your not certain what it will do.

Dudical, thanks... I forgot to ask version number, it is so important.

2fas4utoo! · Jan 13, 2009, 04:40 PM

I'm very sorry is version 10. I didn't connect anything but I was with my mechanic during the installation and he decided to switch from injector pulse to Map signal. I have the following jumpers connected ,MPS and the other one is in PRK. I'm not impatient at all

I'm waiting patiently for your help and won't do anything with out your instructions and advice. Thanks in advance

thanks for the info.

with the v10 it is very easy to switch from IPW to MAP. You leave the wires connected as they were. You must feed in the IDC signal into the PWM pin #17. Then you feed in the map sensor signal to MPS pin #18

Then you put the jumpers to MPS and to PRK.

Let me know if you have any trouble with this.

Thanks a lot! I appreciate your help. Im currently working but as soon as I'm out I'll check on what you told me. I know by a fact that my friend went ahead and disconnected the injector signal cable and use the same cable to intercept the map signal cable. But he didn't move the cable on the small box. Sorry for my ignorance but what do you refer to as IDC?

IDC - Injector Duty Cycle - same as what you call injector signal.

The little box is called the junction box.

If he disconnected the wire from the injector signal and connected it to map sensor, then the DDS3 has no idea what the injector is doing. This is why it will not spray anything but will trigger. It is saying ok I will turn on, but then when it tries to match the IDC there is nothing there.

THANKS A LOT!!! You are the man!!!!

This is exactly what the poblem is...I'm 100% sure it will work now.
