hfs6 affected idle?
 

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.


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

from the aquamist i needed to connect the following.
I used 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.

thank you
