What if...
I believe all shurflo pump can be converted to a "pulseless" system, just need to purchase the pump head, set you back about $50.00. Opt for a 125 psi spring if you are goiung down this route.
I too have spoken to Jeff, the PPS-PWM system conversion is quite straight forward because the DDS3v10 has everything to drive the a FAV (fast acting valve) and pump (via a power relay).
As long as you have a HFS-1 with DDS3v10, you can easily change it to a PWM valve system with one solder link. May be changing the MAF to a FAV (if you are critical on dynamic range)

Few questions since we are on the topic
What thread is the Aquatec pump head Richard?
Will the new flow sensor/fast acting valve work assembly with the DDS3-v10?
Will the DDS3-v10 do direct injection engines, or is there a way to make it do direct injection engines?
HSV for $36.00 is amazingly good, make sure it is a working one. Looks Like you are going to have a complete PWM-valve system. Soldering the DDS3v10 is not too difficult to do.
The aquatec pump hes two 3/8 NPTF thread. It will also accommodate our 3/8 BSP male fittings (with o-ring seal).
Two new products are being launched this month. A new flow 3-map sensor is one. Both FAV and new flow sensor will work with the v10.
You are increditably patient on your research. You know our products very well.

You are are spot on, at 24% dc, a PPS system will flow 50% of its entire capacity.
Here is the entire plot 0-1000cc/m range:
PPS (PWM) Calculated
0 ............... 0 cc/min (theoretical)
20% .......... 446 cc/min (200)
40% .......... 630 cc/min (400)
60% .......... 772 cc/min (600)
80% .......... 892 cc/min (800)
100% ........ 1000 cc/min (1000)
Some of the PPS systems start at 30% (~600cc/min). Other than lack of linearity, the dynamic range is not very impressive either, 1: 1.7 (600-1000cc/min) at best.
The word "progressive" is being used in the most misleading manner to market a PPS system.

The price of the new flow is not yet finalised, I expect it to be it will be about the same as the older one. It has three flow tables instead of one. Flow range ha sbeen extended from 100cc/min to 2500cc/min without loosing accuracy.
For nmnore accurate latest pricing, visit Jeff Howerton. Make sure you tell me the flow range as there are a flow versions.
H1 to H5 conversion:

H1 to H5 conversion:
The flow sensor used on the newer aquamist systems such as HFS-2, 3 and 6 are all frequency based. The frequency decoder in build into the controller.
HFS1, HFS-5 uses a standalone voltage-based flow sensor, the "frequency to voltage" converter is built into the casing.
The DDS3v10 only works with voltage-based flow sensor. A newer voltage based sensor is available in a few weeks time, flow monitoring range is extending to over 2500cc/min. Over the years, we have steadily increase the detection range from 400cc/min upwards without loss of resolution, speed and bearing failure. Progress may be slow but dependable.
Direct injection will belong to another post when we have something more substantial to annouce. Meanwhile, multi-jet/inline valve is the only option.

I am in no hurry to get the kit going. I was more asking about using the kit with direct injection engines and the shorter pulses from the injectors. The HFS stuff can use IDC and 0-5v correct?
Dream for me will be a 2 valve outputs in order to have 2 separated control and triggers...
For example 1 channel for pre-turbo nozzle and 1 channel for UICP nozzle...
But to be honest, I dream because I am not that rich! if I had a million dollars, I will just buy 2 HFS 6 and keep the other 998k to get retired!!!
Without any joke, I agree that I am not that connected to this forum as I used to but I really would like to thank Richard L for all his dedication and time. It is a luck for the whole community to have you here so THANK YOU RICHARD and HAPPY NEW YEAR TO YOU AND ALL AQUAMIST FROM EVOM WI-ADDICTS!
Cheers!

^^That's exactly what I'm putting together right now, I talked to Richard about it & the DDS3 v10 should be able to run 2 FAV's..if it can't he can supply a better driver. Use a boost pressure switch to trigger the second stage.
There will be a HFS-6 replacement coming out at the end of this month with a more advanced "di" decoder. Development is continuously busy for us since the di technology is used on more and more cars. I believe Mitsubishi was one of the first company using the di technology on their gdi cars in the early 2010.
Only the HFS2, 3 and 6 can use the 0-5V input.
Sorry I'm late!!!!

This is the only car in the world that allows the users to tinkle with the ECU themselves with a small donation. All other cars require specialist fees to access the ECU. I am referring to Tephra's alt-map, just brilliant. I enjoy supporting this forum especially all those weird and wonderful projects. More so the intergration of wmi failsafe to the ECU is so seamless.
I hope more people to take adavantage of this wonder machine, e85. wmi and nitrous etc, is ll go go go. As time goes by, factory will make life more and more difficult for anyone to access their ECU, so goldern era is here for those who like to play.
As regarding a two-channel with independent trigger point. It will be introduced soemtime in the near future. If the economic climate shows some upward trend, you will see this option sooner than you think. Of cause if anyone donate a million dollars to us... it will be nino seconds.
Pretty simle really, I am going to split the signal from the DDS3 to the FAV & wire a pressure switch in series for the second FAV. One FAV will be pre-turbo & the other will be post-turbo, testing will determine which will be primary or secondary.
Primary stage will be triggered by IDC & the secondary will be triggered by boost.
