Nothing attached

 

 

I that's all I have already set it to that exactly ... top water injection light is on pump is primed vis sys jumper

is that the way I need to set my jumpers? That's the way I have them set

 

Green light is flashing like normal but nothing else.

 

 

E-mail sent It's for the HFS-4 though.

 

Ok here's where I'm at

jumper in sys flows great no bars on gauge (w/ dial adjusting also)

jumper in bar. 6 bars on gauge

S and b light up no other lights on

pulled jumper from mode pump is on and flows with throttle

Other than that I have no flow in regular operation or bars on gauge light up

rechecked all wiring seems fine

on board green led works as it should no other led comes on unless in sys

The only wiring difference I've done from your manual is wired the red line from gray harness directly into battery
anyone have any ideas what's not right?

 

I had lotsa grief with my HFS4 'cause I was using methanol that wasn't pure enough --- it plugged the FAV. Is your system flowing at the final outlet?

 

Yes in sys or mode jumper pulled this morning I pulled the jet and replaced it with a blank

with mode jumper pulled it was running stronger with rpms too

running like 80% meth atm

 

"---pulled the jet and replaced it with a blank"??? Guess I don't understand what's wrong and what you're trying to do. My understanding of "a blank" is it's a plug, allowing no flow.

One last thought --- I didn't connect the fail-safe feature on my HFS4, mainly 'cause I don't have the same turbo features on my big Garrett. System has been working fine for a few years, just probably not as safe as it should be. Maybe disable your fail-safe to see if that fixes your problem --- if the HFS3 has a fail-safe.

 

Put the blank on the intake tube I'm not retarded lol so I could run it with it out

 

Front and back setting

 

So tonight I cut MPs 3 and soldered mps2 I have flow now with thres led still no gauge reading no matter what I do
I also soldered all connections to ensure they were good

running about %80 meth no cooler iat
spray comes at about 8psi boost

anyone have any ideas

 

Check connection to flow sensor at FAV. The flow sensor out put is what drives the gauge leds after processing by the HFS.

 

Just a guess but also check page 20 of the v3.1 manual in regards to IDC pre-scalars for DI. Looks like back jumper should be C to B (good) and the other should be B to A instead of A to A.

 

Tigger if I wanted to just replace my board with a hfs4 will my system work with it?

 

You could if you wanted to but honestly with the improvements they made in the v3.1 design I don't think it necessary. With 3.1 they refined the DI portion and still allow you to mix boost and IDC for your threshold. You don't have the same level of adjust-ability between those two (see below) but it should work well in our application. I've never installed the HFS3 just the HFS4, AEM and Boost Cooler 2 units. I went thru the manuals and came up with the following. The first addresses the pre-scaler for the IDC as noted previously.

These should be the correct jumper positions on the front. Black dots are default but DR0 goes to DR1 to prevent a CEL during failsafe trigger.


See notes below for the back side. 1. is based on the HFS4 configuration as the HFS3 and HFS4 manuals are silent as to their function.
By bridging IDC and MPS on #4 the system will spray based on 70% IDC signal and 30% Boost.
The S model uses a 2.5 bar MAP sensor and the JCW uses a 3 bar sensor. If not running over 22 psi configure 6 to bridge to 2. Pad two will work with 2 to 2.5 bar sensors and 3 is for 3 to 3.5 bar sensors.
Finally on #7 pads 1 and 2 should be bridged as your running a single nozzle and will be spraying 500 cc/min or less. This effects your flow range and in conjunction with the SC pot on the gauge determines the bars displayed on the gauge.

Hope this helps.

I am running over 22 psi hit about 26 have a hybrid turbo

on back
1 should be bridged to c? Mine is to b

 

The HFS-4 is bridged to C. I see someone with a similar problem is talking to Richard at Aquamist. If that's you I'd run it past him.

Sending this from my phone as internet is down ATM. I'll upload pics of my HSF-4 config shortly.

 

It's not me but if you see what he says please forward the info what about my little bit of higher boost think that will matter?
thank you for helping

 

Here's the Front of the HFS-4. On the right the dashed circles are the default factory setting. I circled current setting with a sharpie.


Here's the back side. Not the prettiest solder joints but I was in a hurry lol.


The voltage output on the MAP sensors is the same 0-5v. The difference is the S sensor output's 4.5v at 250 kPa while the JCW puts out 4.5v at 300 kPa. This is on a linear scale. Both sensors will read accurately to about 4.85v so they will effectively report 1.6 bar and 2.1 bar of boost at sea level baro pressure. With the board configured for 3 bar but being feed voltage by a 2.5 bar sensor the boost will be under reported. You'll still get a signal so it should still work, but its been noted that I'm a bit OCD.

The Aquamist forum is a wealth of information and Richard has been a huge help for many. I noted the Hall effect pick up on your flow sensor is mounted at the 12 o'clock position. I would try rotating it to the 3 o'clock position. I found mine worked best at the 2 o'clock position.

 

Ty for the guidance I've been searching for the info on the ABC can't find anting on it do you know what it does?
I wrote Richard and it's been a over a week with no reply

I became a member of the forum but can't post in it

 

Haven't found anything yet on the ABC but PM'ed you a link that might help. Check post #7.

 

So I have the system running with what I think is good flow starting at about 10psi.

I am am running a .7 jet and running about 80% meth I'm not see any AIT cooling I checked for a restrictor but do not have one.

Tigger do you think I need a bigger jet? Car has upper 200's hp

ps still no bars during flow on gauge

 

I'd recommend a 1.0 nozzle at that power level. Did you tape it to the windshield to verify it's spraying? With a 0.7mm nozzle you should be seeing a drop in inlet temp.
