Hey all!
So I got an hfs-3 system used and installed in the past week. I have everything wired up and mounted but have three problems that I cannot solve.
1. When testing the system, if I set threshold all the way counter clock wise and blip the accelerator I get amber on the module and the pump kicks on. I also get yellow water injection and yellow water level lights . After a second or two from delivery, the lights turn off. First the water injection, then the water level.
2. The FAV is not working from what I understand. The pump turns on as I have said above, but no water sprays from the nozzle. I feel like this is not normal. There is water present before the valve but not after.
3. After turning off the car the Pump powers on full and the valve opens spraying water for around 3 seconds. I understand that my dme does this after engine stop but I don't know why the valve would not restrict this. I have angel eyes tapped into dme power (not the same as aquamist) and they turn off at the exact time of the pump. Both are a power source from ignition position 2.
Background info
2003 BMW 330i supercharged
No fail safe in place, all wires capped.
I pulled the jumpers on the aquamist board from the fail safe . I am not sure of this is correct but I am not going to be using a fail safe option.
I believe I have
Inj, pwm, DBO, and one other jumper that I cannot remember.
Wires are injector + to 12v before fuel injector relay
Injector - to cylinder 2 injector ground after dme
Red power to 12v ignition position 2 source
Long story short,
Delivery indication good. Flicker of green on board good (faster with rpm) pump kicks on in delivery threshold. No spray at any time and both gauge yellow lights illuminate. Only sprays after engine shutdown or by bypassing valve.
