I just installed my HFS-1 with DDS3, im sure everything is connected up correctly. System turns on and applies mist at 10psi, but on the Flow Guage i get 3 bars (200) at inital onset, and 2 bars (150) for the rest of the pull.

What else can i check to get the flow up to the 300-400s?

 

What size jets did you install and how many? How much peak boost?

 

Not sure the size of jet, 1 installed and i got it from a member here, will ask him. Im thinking its the 0.8. Im running GT35R 25-27Psi without kit, and with kit on i plan to boost 30-35. But just wanted to check out the flow problem(if it is one)

 

Now it spikes up to full fllow for the inital onset, then drops to 2bars again. Maybe the 2 bars is normal. No leaks or anything. Ill try and change grounds and see what happens But all in all it is consistant.

 

Definetly check your wiring. Keep your eye on the afr's if they are normal, it is probably electrical gremlins.

 

Put the jet outside and manually trigger the system by removing the IDC sensing wire and ground it.

Observe the spray pattern.

possible problem:
1) clogged filter............ reverse flush
2) trapped air in the pump head ........... prime and purge the system without jet.
3) partially clogged nozzle ........... poor spray pattern
4) Flow sensor filter clogged ......... reverse flush
5) Debris trapped inside the flow sensor. Sensor serial number below 3000 is not serviceable.

 

ok will try all that today, and see what i come up with.

 

If you don't know the size of the jet you know nothing.


1) Discharge Formulas

a. With Nozzle

Discharge (GPM) = 30 X Diameter of Nozzle2 X ÖNozzle Pressure

GPM = 30d2ÖP

 

The jets that aquamist uses are color coded. When you pull it out of you pipe look toward the end of the jet. There should be a small colored band on it. This color will match to a jet size on the flow sheet. Look closely purple and black bands look very similar.

 

Im about to check everything out now. I think its a Black band.

Got the Kit used with no information or instructions. Everything was down by sourcing the information online. Thanks for the gpm formula.

 

ok So i went out and removed and checked everything again. No Bubbles in lines, and re-primed pump.
Looks like on the DDS box SENSOR C (Green Wire) wont stay in.
But besides that all other wires are fine. Hooked the IDC to a Ground, and have Good Spray Patter, with the same low flow indication on the gauge. This time showing 1Bar insted of 2. I even swapped grounds on the pump, and for the Trigger. Same result. Also noticed a small leak from the the 4mm connection on Sol. Valve, Flow sensor IN/OUT. (maybe this small leak is the problem)

Another question i have is on the Solenoid Valve there are 2 wires BROWN and GRAY.
I have the Brown connected to RELAY+, and Gray to RELAY-. Is this Correct?

*Dont mined the blue elec tape, thats just there for the testings.*

 

The green wire is responsible for adjusting the gain of the bargraph. You can relocate the green wire to pin 4 (from left top down) twisted together with the white wire. Let me know.

Here is a HFS1-v8 wiring diagram for your car:

 

ok, yeah i used the one with EBC, but i have the AVCR so wasnt sure how to hook into the Sol Valve. so i left the lower side open. Dont have MAC valve, guess i will have to invest in 1. Will swap over the wire in the morning and let you know.
Thanks

 

I will post a diagram for ebc later on to day.

BTW, very nice install.
