Aquamist HFS-5 system: Official Q&A...
#79
Richard,
I installed the fuel injector summer this weekend and I have some questions. First, the summer replaces all of the FIA2 connections, so am I right in assuming it is eliminated? I removed it completely since the injector inputs now come into the summer, and the HSV output now goes out of the summer, and the summer now inputs to the DDS3v8 to the two contacts that were once occupied by the FIA2 outputs.
Anyway, I recalibrated my flow guage by grounding the trigger terminal and the system flows fine. However in normal driving I cant get the system to activate. I dropped the potentiometer on the DDS3 to the minimum and it still won't trigger. I went all the way up to 15psi of boost 6000rpm which in my setup is 70% IDC and it still didn't tirgger.
The summer is lighting it's LEDs like it sees the injectors. It sees the primary at idle and the secondary LED does light when enough throttle is applied...but still no system activation.
So there is my roadblock.

OK, the summer is seeing the two signals.
Does the summer led comes on? (red led).
Have you managed to calibrated the potentiometer to match your injector size?

Richard,
I sent you an email, reply to that or give me a call. The red light comes on when I manually trigger the system. I had thought you said you were going to configure the summer to my injector sizes prior to shipping it to me? If not then I definately need to do that, because I did omit that step.
Yes, all four wires from the summer are connected to the DDS3. I had to double up the wire from the flow sensor and the wire from the Summer at the SensorV pin, and the output power wire of the summer now goes to the input power pin of the DDS3.
Is it correct to get rid of the FIA2?

Hi Richard.. been trying to contact you about buying this setup. I know you're probably busy this holiday season but when you get a chance you might check your PM. Cheers man and happy new year.

I am looking forward to the some feedback. I have send a dozen out to various people so far and so I have not got any practical results jyst yet, I assume most people got the HFS-5 kit will not be installing the system until they have the entire set up.

HFS5-summer wiring diagram
I have just completed the HFS-5 to summer interfacing diagram for those who needs it

Thanks Richard for the Diagram
My has been out action for a year until last month, going to rewire the whole lot next month as I have a new Motec system fitted, I will take pics along the way

Think you are getting confused Marco, 12% is lowest trigger point of fuel duty cycle, so soon as you hit 12% fuel injector duty it will come in, (too early imo), and the latest point you have it start to come into is 72% ( too late imo)
Mine did come in around 40%.

Richard,
I am getting ready for a massive rework of my whole setup, the focus being on electrical routing and component control. . .
I am running peak and hold type secondaries and saturation type primaries. That being the case, the summer won't work for me. I still definitely want to use the DDS3v8 box so that I can use the gauge and all of the features it affords (flow sensing, low AI level indicator, failsafe wastegate actuation, etc.). I think that the best way for me to control the HSV is to use a PWM controller from my Haltech. I'm no Electrical Engineer (by any stretch of the imagination), so please help me understand the best way to configure this system.
It seems to me, that if I run the PWM controller wire to the FIA2-TRIG junction, that I will be controlling the HSV (and thus the injection rate) via pulse width modulation. I can then just map the PWM in my Haltech to match up at a fixed rate (or any rate I wish for that matter) relative to the fuel. If this would work, that would be excellent for my particular setup sheerly due to the simplicity and cleanliness of the loom(s) I'd have to build.
Please shed some light for me.
Thank you kindly.

Ryan,
If you run "peak and hold" drivers, put the IDC sensing wire on thre input side of the "peak and hold" driver.
If you already have FIA2 unit, you can use it to detect the p&H driver. I can modify the summer to read "peak and hold" injector but so far no requests.
Alternatively, as mentioned by you, use a spare PWM output channel from the Haltech to make your own methanol map. You can create a 16x16 table?

One useful feature of the Summer module.
It can scale the meth flow up or down electronically via the third calibration potentiometer.
With the same principle, primary or secondary can also be re-scaled.
