I searched and couldn't really find the answer I was looking for.... so here goes:

Has anyone used these two systems together? The Haltech doesnt have a quick way to jump from a meth program to a non-meth program... atleast that I know of??

So does that mean you have to run around with the meth program loaded and the system activated all the time? I never know when I am gonna feel the urge to get up into some boost.

Is it bad for the pump to always be activated or turned on while driving around town?

My thinking is this.... and please feel free to correct me if I am wrong... I am here to learn: You load the meth program and under normal driving situations and low boost situations (under 10psi) it wouldn't hurt to leave the pump turned off, then when you felt the need.... reach over and turn it on and hammer down. Right?

Second point: So I could simply wire one of the failsafes in line of the boost controller before or after the Haltech? This way if there is a problem it falls back to the wastegate spring, right?

Finally, does the HSF5 come with a tank? Every pic I see there is no tank. For the price, it should come with atleast a 1.5 gal.

 

Wait for the HFS-6 if you can...

You could set up a boost map that is tuned for METH above a certain psi and have the haltech aux output triggered to go hot when you are above that set point. Have a relay turn on your METH system from that signal. Set up a failsafe as you indicate to cut boost.

I'm hoping the Haltech will be coming out with something here shortly that will really make this more elegant from a control/implementation standpoint (need more programmable inputs/outputs).

 

Frankie628 had snow kit with haltech, it didn't work out well somehow..He running Turbonetic with haltech.

Thanks RC. This is exactly the info I was hunting for.... but one other question:

How quickly does the pump/system turn on? You know how fast these things make boost... in a nano second I go from 10psi to 15psi. I worry that the activation might not be fast enough and cause a slight delay.... just enough to nip a plug or worse melt something down. I thought this kit had an on/off switch? Although with your line of thinking.... I could have the relay switch the kit on at a lower boost level like around 5psi, but not start the spray until say 12psi or higher.... that might give it enough time, right? Or do these systems hold line pressure? If they do, then my line of thinking would be wrong. There would be no delay at all.

With all the bells and whistles of the Haltech... I am kinda surprised they haven't come up with some kind of nifty plug and play deal for the meth kits. They are very popular and have been around for a few years now.

 

why would you tune that aggro?

either way, the lines stay full, so once the solenoid activates, it sprays. I'd also figure with the outrageous pricing of the aquamist setups, you can increase the spraying pressure as the boost rises, ie 50% at x psi and ramping up to 100% by y psi.

so the haltech cant control nitrous either? nitrous and meth both trigger the same way.

 

the HFS doesnt rely on pump pressure to deliver the meth, the pump pressure stays constant and a solenoid controls the injection. Think of it as a regular fuel pump and fuel injector system

The pump has its own bypass so it keeps the pressure constant so you dont have to worry about line pressure being too high or low.

Im not sure if you can run the pump 100% of the time, but you can use the outputs on the haltech and some of the if/and triggers to turn the pump on when certain conditions are met, same thing with nitrous control

 

Will the ProEfi have these same issue? Im looking for a EMS that will do this without an issue. i honestly dont wanna run around with a pump on all day just incase i wanna get froggy. Plus having to drive around with a laptop just to change maps isnt too appealing either...

 

Thanks for all the replys.

 

I'm still waiting for my W/M kit. So can't tell you from experience there. I see no problem having the pump on all the time, ready to spray. Is there any reason not to? Keep in mind that the failsafe has to act instantly to be effective, so that would be your safeguard I suppose if the pump is slow to turn on. I had planned to run the pump on when the car was running - 100% all the time.

In regards to the Haltech integration, I suppose one reason for not building in a fancy controller is that good controllers already exist, as an add on from a number of vendors. So why increase the cost for each EMS sold? I do believe the programmable input/output box is coming soon. That should make tighter integration possible, with redundant failsafes, etc.

 

really u just want some sort of feedback to the haltech, like u can do with the fcon, so that it will automatically switch maps if it gets a trigger like low fluid, clog etc.

 

I agree. Even a relay triggered boost cut is not instantaneous, but an electronic intervention from the Haltech could be.

 

Does anyone know if the HSF-6 is available? GTM lists it on their site... I tried calling three times today and got a busy signal every time, so I sent Sam a PM about it and still have not heard back yet? I guess if I cant get any answers, I'll just order the coolingmist kit. I am gonna need this thing in the next few days.

 

PM George@GTM also. The first batch of units are supposed to be released this month and I think you can pre-order and maybe claim one of these that are on its way to GTM (they are an authorized aquamist dealer). I really am not sure if all the units in the first batch are spoken for. I think it will be worth the wait based on what I've read up on this little unit so far.

 

Anyone know the difference in the HSF-5 and -6?

 

NM I found it and YES, I am just gonna wait till it gets here.
