Aquamist HFS-3 (with summer) vs. HFS-6
 
Hey guys,

I've been using the Aquamist 1s kit for some years now and think it's about time to step up into something a little more intelligent. I really like the Aquamist product so I plan on sticking with them.

Problem is, I'm not really sure what the main difference is between an HFS-3 and an HFS-6. I know that the summers are a hot commodity and difficult to source (but well worth it if done) however I am not sure if it would be needed with an HFS-6.

Can anybody break down the primary differences between an HFS-3 (using a Summer) and an HFS-6 in a relatively dumbed down manner?

Thanks!

Levi

Somebody, anybody.... Nobody?

If you find out I would like to know since it looks like the Summer GB isn't going to happen. David from Aquamist would be the man to answer this.

Go to the aquamist forum. The GB thread has this exact info.

Who told you the GB isn't happening?

The system has been planned for some time, right after the launch of the HFS-6. We want to be certain the core components are totally reliable before launching the second PWM system.

THF HFS-6 has provided us a sound foundation and quick development time.

The HFS-3 is an affordable entry-level system for those who wants to venture into the PWM valve concept, allowing "wide dynamic range" and "fast response to load change".

Please feel free to post questions.

- It doesn't have manifold pressure compensation, but can use it as a reference for injection (see below).
- 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

The HFS-3 can:
- scale-up/down the incoming F-IDC for car with very large fuel injector that doesn't run up to 100%.
- You can run the system based on boost or IDC only. In single stage or progressive mode.

The HFS-6 is more suited for engine with large turbo with power beyond 550whp.
