Anyone here used the aquamist controller? looking for pcm pinout help I purchased a used unit and proceeded to install using this instruction.
http://www.aquamist.co.uk/HFS6/HFS-6-4w.pdf
new lines were used and i was able to do a manual test.
aside from the flow control Ethernet plug being a little loose the system sprays. everything seems fine
however once i start it, it affects the idle tune of the car. it starts stumbling and a quick rev would make the car die.
unplugging the ecu plug from the hsf6 unit and the car runs normal again.
here is the ecu pinout for my 1998 transam
http://www.lt1swap.com/1998_ls1_pcm_pinouts.htm
from the aquamist i needed to connect the following.
I used the following. which i connected to the following
IGNITION SW. (INJECTOR +)
Blue connector pin 19
FUEL INJECTOR (-)
red connector pin 33
MAP SENSOR (0-5V)
BLUE connector (pin 48)
The only thing I can think of is the fuel injector - is connected wrong. I noticed what looks like a black smoke like its turning on the injectors?
anyone have a suggestion on which connector to tap into.
thanks

First off, what kit did you buy? HFS-3 or 6? Let me look to see if I have install directions. I don't think you need to connect to the map sensor or both of the injector wires. I think the only thing you need to connect to in the engine bay is the signal wire for the fuel injector since the system is driven based on injector duty cycle so it relies on injector pulsewidth to determine how much to flow.
To me, it sounds like you have accidentally wired it to be active all the time, so that's why it's flooding your car.

I'm in the middle of installing a HFS-3 system in my 98 F-Body. Just want to confirm I should only connect to the PCM (injector + and - pins) identified above and not the MAF signal as well?
Thanks!
Thanks!

So I have the system installed and I connected the grey ECU harness (Injector + wire) to the blue connector pin 19 and the (Injector -) to the red connector pin 33. When I turn the system on to check the wiring/electrical, I am not seeing any green LED's on the dash gauge, so it's not seeing/detecting the F-IDC. Any ideas how best to troubleshoot this? Do I need to use the green harness to connect to the injectors instead?
