Aquamist HFS-3 system for 2010 ..... "Q and A" - Page 8

Richard, my installer is confused a little. The kit is going on a Subaru wrx so a wiring diagram would help for that model car. His question is concerning the harness with all the wires. The instructions say to just connect 3 ofthose to the ECU. do you do anything else with the other wires? And he's got other questions. Can I just put him in touch with you as I'm not there in person during the install.

What is the best way to communicate? I would think by phone. Is there a number he can use to call you?

Thanks

Hi, was in the same boat. They're just real busy over there. It's not too bad once you figure out where all the stuff goes. Check out the "HFS-6 wiring diagrams for specific model of cars" in the forum. You should be able to get the info you need from there on the rex.

Also I can highly recommend tapping the wires (especially ECU) with posi-taps. Makes for a clean and easy removal as well.

I will speed up my HFS-3/subaru diagrams. I have all the infos here but lack of time.

Meanwhile, you can use the HFS6/Subray (h6 forum), the wiring is almost the same, The ECU pin out is identical.

I will do the 05wrx wiring diagram next, I think it is your car?

hey richard any thoughts on my problems??

For #1 you need to scale the gauge with the SC pot. Put the system in test and set the gauge to 6 of 8 bars.

For #2 fiX the scaling first above and see how the problem changes. I can say if you are trying to run right off 12% IDC then the system will be very sensitive on the low end.

HL and HW are respectivly set at their maxes so it shouldnt light the yellow LED. i have two problems.

1) on initial start the 8 flow lights light up then it settle to 7lights. is that cuz i am using jets that are too big??
2) on spoolup i get the failsafe yellow led flash up. i have worked out if the car remains at low IDC for long enough (like going up a hill with lowish boost) the light will come up. or if i load the car in higher gear like the 6th the light will come up. i have also worked out that if i rotate the thresh till 3rd line (about 20-23IDC) then the light does not come up.... except that means the meth does not start till i am running 16-18psi... i want it comming on at 5-10psi or about 12-15% IDC. as i am soon moving to a place where i dont have access to good quality fuel.

can anything be done??

so i should connect the BAR jumpers right???

anyway tried playing with the SC... but still if i have the thresh low the failsafe comes on. currently at the 3rd line (1st line is 12%) it is ok for a 3rd gear pull but not for a 4th gear from 2500rpm.

i have changed my restrictor to a 0.9mm (it was 0.7/middle one before) so see what happens in the morning.
