Aquamist's new HFS-3 for 2010, replacing the HFS-1
 

^^^ I have anxiously waiting for this day :D

These kits I imagine will be like the HFS-6 and not ready till summer 2010.
Richard has so much work he has been doing and have yet to do!{thumbup}

Patience to all.

Awesome! Just to clarify, this is a single-stage kit, right? On/off, based on IDC or manifold pressure?

This is a full progressive PWM kit. Here is Richard's quote form another forum:

"The HFS-3 is very similar to the discontinued HFS-5, it mirrors the fuel flow at 1:1 ratio. You can change the ratio by sizing the water jet. However, it does have a gain trimmers to allow some form of rescaling to compensate for large fuel injectors that do not run up to 100%.

It does not have the full set of adjustments offered by the HFS-6.

The aim of this system is to update the HFS-1 to become a P&P progressive system at minimise cost to the end user. Utilising the PWM-valve setup to gain large dynamic flow range ."

Evan,

Happy New Year!

The HFS-3 is ready for shipping in Jan/Feb, starting with GB as before. I will post up GB details in January.

It is our aim to make all of systems "plug and play", avoid the installation cost over-whelming the system cost.

Each and every component is terminated with a plug, making connections in seconds rather minutes. Replacing suspect component is a breezy.

No, it is a progressive system.

We have acquired/learnt knowledge over the last two years on how to make a fast actiing valve in house. With this knowledge, the cost of an inline valve has reduced considerably compared to buy from a third party.

The HFS-3 component list is now satiisfactory and complete, ready to be incorpoated into a final product, at a cost comparable to a PPS system. We are now entering into a new market place, just hope people will appreciate the wide dynamic performance of a PWM-valve system.

Holy crap that is insane! So would you mind educating us as to what the exact differences are between the -3 and the -6 kits? Both are progressive, both seem to have dynamic flow ranges, so the waters get a bit muddy.

Does the -3 have the ability to shape overall flow? i.e. using oversized jets and then scale back peak flow to say 60% of what those jets are fully capable of. (this is a feature of the -6 IIRC).

Also, can the trigger be a combination of both IDC and boost pressure, or must it be one or the other?

All the stuff he said scheides is a smart guy {thumbup}. I'm more concerned with the major difference between both kits cause I'm trying to figure which kit is more suited for me and the power I'm making

Hehe thanks :) It's not really about the power you're making, its about how you intend to use it. There's 600+whp cars running old-school SMC kits just fine, but real world, on the road, drag strip, open track, etc there advantages to the different kits. If we can clearly define them, we'll be in good shape :)

The HFS-3's adjustability is limited compared to the HFS-6.

It cannot (compared to the HFS-6):
- offset against the initial F-IDC - the F-IDC threshold % = starting point of meth flow %
- It doesn't have manifold pressure compensation
- alter the failsafe reset period = pegged at 3 seconds
- read "Direct Injection" pulses such as the 335i or Audi FSI pulses
- control a MAC valve directly as with the HFS-6

It can:
- put gain on the incoming F-IDC for purpose of having large fuel injectors running low DC. Previously, the HFS-5 has to be double pulsed.
- You can run the system based on boost or IDC only. In single stage or progressive mode.
- You can program it to be single point (HFS-1) or PWM-V mode (HFS-5).


The HFS-6 has futher electronic signal processing to match the FAV's opening and closing period. That is all I can think of so far.

Fantastic! the -3 sounds like an amazing setup! Can you explain how it supports boost trigger with progressive mode? Does the boost trigger have two trigger points, for min and max flow, like an SMC kit?

Furthermore, when triggering via IDC, does it work the same way? Low/high trigger point?

You are always one step ahead of before update. Slow down!

OK, IDC or MPS after trigger, we just set the gain trimmer until the 95% IDC led (red led) lights up. At this point you know you have reached the full flow of the system.

I doubt if anyone would want to use boost pressure as reference for meth injection as you have IDC. Still, it can be done on the HFS-3. For the same reason, any 0-5V signal can do the same thing.

I will be posting the next update on the functions of the contoller. I have left enough space on top.

Happy new year and happy holidays to you!



Wow it must be because the HFS-6 was a good foundation for the new platforms that allowed such quick development time. {thumbup}

The HFS-3 seems to be for those who want to set a system up them selfs and not worry about over adjusting. I.E EMS on a stock turbo evo... kinda over kill.

The HFS-6 can also be fully implemented for other control aspects. Such as EGT, boost, IPW, even water oil temps if you want. lol Think of the HFS-3 as a HSF-5 but plug and play at the cost of the HFS-1. + extras{thumbup}


Great Job Richard and ERL!
