I'm sure that if you could post the instruction manuals and any other information pertaining to the kit, or at least links to them, that would be greatly helpful. I for one am still not 100% crystal clear on the IDC summer operation form the last thread.

Please help me understand using my specific example.

I have a 3-rotor with 3x850cc primaries and 3x1680cc secondaries.

I turn the 1st **** to 850cc
I turn the 2nd **** to 1680cc
I turn the 3rd **** to 3 (since I have 3 injectors)?
Is this correct?

Once I have told the HFS-5 how much fuel I'm delivering using the summer, how do I tell it what % of the fuel I'd like it to deliver as AI? Is this done purely with nozzle size selection?

Thanks.
ryan

big_rizzlah,

This is a great point to start the discussion since a few of you will be using the IDC summer with the HFS-5 sometime in the future.

The summer converts two channels of PWM signals from the fuel injector and output as one (summed).

At this stage, all you want to know is how this is connected and calibrated to suit your setup. I will do this in steps:

1) Pick up the DC signals from the any one of the primary and secondary injector.

2) Dial in the flow capacity of the injector with the two *****, ch1 (primary) and ch2 (secondary).

3) Adjust the third **** to set the scale of the output PWM to 0-100%. Actual Flow is not import at this stage as it will depend on the water jet/jets size. All we are interested is the output scale to be 0-100% in relationship with the PWM sum of the two idc signals.

Taking this is step further. The third **** can be used to control the ratio of fuel/methanol ratio.

I'm not sure where in the development of this summer device you are, and additionally, I am no expert in electrical engineering.

As a user, I think it would be the BEST if your summer worked with a very simple computer interface. Just hook it up using a USB or 9-pin I/O connector or whatever and have the user specify three things.

1) primary injector size
2) secondary injector size
3) desired flow rate of AI at MAX flow through both primary and secondary

The benefits would be HUGE

- VERY easy to use, the user simply types in a number value for the injector sizes, could be any value, no need to have a scalable **** that is less accurate.
- VERY easy to tune, the AI will ALWAYS be proportional to the fuel. You could paactically ignore the system in terms of tuning, just set the value you want injecting, and tune your car as usual, except now for some magical reason (god bless AI) your AITs, EGTs, and knock are through the floor. no brainer tuning. HUGE ++++ for a large majority of the market, very marketable as no tuning required.

To me, this is the easiest and most robust type of configuration that you could have, from an end user standpoint.

sorry if this is out of place in this thread, but I really think that what I've proposed is THE answer, someone smarter than me please weigh in.

So have these shipped to Jack yet? I was in on the group buy that was listed on the SRT-4 forum. I haven't gotten a call from Jack yet but I am eagerly awaiting!! Hope to get to play with this thing soon!!!

Richard L

You should get a call from Jack in the middle of next week. I believe you are on the second shipment.

don't sweat it cozmo. . .you will definitely get your call. . .i got mine just the other night, and Jack is real easy to talk to and offers up a ton of support.

i'm QUITE confident that we just made a great move in getting in on this. . .

I have a question.. where can I buy the HFS-5 system? Can I purchase directly through you Richard? I tried contacting you (pm) but no reply. Thanks.

aqmist

Cozmo, I got the second shipment in yesterday afternoon (03-02-07). Keep a look out for a phone call or email tonight or tomorrow. I'll need CC info to pass to Richard, after he charges the CC he will confirm to me and I'll ship. I'm at work right now packing these up so that I can ship out Monday or Tuesday at the earliest.

ky7, In a couple of weeks more kits will be available at Aquamist retailers worldwide. If you can make contact with me via email I can let you know as soon as they are available.

jackblalock(AT)gmail.com

To everyone, I get hit with many emails on this kit as well as other questions but I try my best to get back as soon as possible so be patient, I will return the query with good info as best I can.

I can also help with stuff over the phone, I have a dedicated Aquamist number at my home office (908) 781-2002 which I can take calls to or make from. I'm at this number between 7:00 and 10:00 PM (GMT-5 = New Jersey)....same thing with emails, I get a lot of calls and make a lot calls so if busy or get answer machine leave message I will return the call.

O'yeah, I'm not a tuner or very up to date will all car makes = But I'm pretty good with W/A.

post #1 has been updated... please read the warning.

I have a very bad habit of missing pms. I am sorry that I hadn't reply. It was not intentional.

You can email me on richard@aquamist.co.uk directly. I check my email very regularily.

I received my kit last week and have two questions. I'm sure I'll have a bunch once I start installing it but anyway...

1. I want to trigger the system only under boost (maybe 3 psi) and regulate flow via injector duty cycle. Can I use the stock boost sensor to trigger the system?

2. There are 3 small brass restrictors included in the kit. I don't see any mention of them in the instructions. What is their purpose, how do I install them and generally what effect will they have to total flow assuming they somehow reduce flow?

TIA

KY7 . I pm'ed you back. you can join the UK group buy on fduk if you wish. Mail me if you are interested becasue i lost your email add sdminus@yahoo.co.uk

I received my kit last week and have two questions. I'm sure I'll have a bunch once I start installing it but anyway...

1. I want to trigger the system only under boost (maybe 3 psi) and regulate flow via injector duty cycle. Can I use the stock boost sensor to trigger the system?

You can use a 806-157 MPS (Manifold Pressure Switch) tee'ed into a vac port and wired in sequence between the junction box trigger out (pin #25) and the FIA2 so that for instance you can have W/A trigger on FIDC and boost. If you only want boost you can adjust FIDC trigger to a lower setting and leave the 806-157 as the determining point or turn on reference. To do this wire the trigger blue wire from the junction box (pin #25) ......on terminal on the MPS......then from this same terminal to the #3 pin on the FIA2.......from the other terminal of the MPS run a wire to pin #1 on the FIA.

2. There are 3 small brass restrictors included in the kit. I don't see any mention of them in the instructions. What is their purpose, how do I install them and generally what effect will they have to total flow assuming they somehow reduce flow?

By Richard within another thread......"Restrictor: These restrictors are placed upstream of the HSV. They are calibrated for matching your combined fluid flow of your jet/jets. It is not critical for exact matching due to manifold pressure and maximum duty cycle of your injector.
It is recommended to use a restrictor size higher than the jet/jets can managed. They are mentioned on the user manual very briefly. Page 12, first paragraph - last sentence."

Whoa, I think I understand the theory here for #1 but I thought I could use the wiring diagram on page 15. It looks like what I want, where injection is triggered by boost and flow rate is controlled by injector duty cycle. I am just wondering if I need your MPS 806-157 or if I can use my stock pressure sensor. Maybe it depends on the voltage output of my sensor. I guess I would need to find the answer to my voltage myself but assuming the voltage is no more than 5 volts I could use it right?

#2 Hmmm, ok so for example if I am using the 0.8 jet, which is good for about 400 cc/min according to the chart on page 12 or 300 cc/min according to Jack's e-mail then I should use the 0.5mm restrictor because on the little bag it says 420cc/min? Is this correct? Likewise the 0.7 restrictor should be used with the 1.0 jet and the 0.9 restrictor should be used with dual jets. Am I on target with my understanding? What happens if I don't use a restrictor?

Sorry to rehash this but I want to understand my kit 100%.

Hello, page 15 is showing MAP as the trigger. I misspoke, my apologies.....I saw OR read boost pressure and was not careful in my reply. You can use the MAP, the default trigger out of the box will be 50%, do not forget that you can use the trip adjust to tweak this between 25 - 75%. Also, do not forget to set/use the appropriate jumper setting within the Junction box MAP/MPS or PWM

Richard will PM or email you to better explain use of the restrictors supplied with the kit.

Richard L

For those who are concerned about the failsafe drop out delay (~2 seconds) as default setting, It can be trimmed down to 0.3 second or faster.

I support it is too early to go into details as not many of you have yet install the kit.

Hi Richard eagerly awaiting your kit on Tuesday, One question can I connect the ground switch output to my boost controller?, so when it is in the safe flow rate the switch output switches my boost controller "on" and when its not it , its switches the controller off therefore it will lower my boost and just use wastegate spring pressure?

Richard L

yes, the ground connection to you boost controller output is an ideal place to splice in the "failsafe cut" from pin11,12 of the DDS3's junction box.

dis1

Wow, great question. I was thinking of doing this but didn't know if it would work.

Any word on those IDC summers for us rotary customers?

Just checkin since I'm getting closer and closer to finishing everything up.

Thanks
