Re: Hfs-4 wiring for Audi B8 s4 3.0 (2009-2013)?
I am having problem understanding your description.
Pin 37/T60 is the pre-TB MAP sensor

Sorry I typed wrong it's pin 86 t90 for passenger, and 65 t90 for the driver. These are post supercharger map sensors. I did not check the map located near the TB. |

I am still confused, about the driver and passenger. Are they important?

I still seem to be getting this strange rushing up and down on the flow meter. Like as it activated and spray is happening, the flow meter rushes up but goes up and down during acceleration. It doesn't seem like there is a steady flow. Could a bad fav cause something like this? I'll try to grab a video. I can be making 18psi of boost, but hit 60-70% at Max, but as it continues spraying, it's going anywhere between 25-75% flickering. Other times I'll strangely see 90%+ with the same amount of boost. Ive watched some videos online and the flow seems to be quite solid from what I seen. Ramp up goes and then I see people spraying 100% not flickering. |

I now understand 100%. It doesn't really matter which, as long as we have some information regarding the pressure post TB. Aquamist system uses F-IDC to meter flow. Boost pressure is used for correct purposes only.
The flow should not be rushing up and down at all, there is something wrong. One way we can find if the system is reading the IDC% properly or not: link "FDC" jumper and see if the incoming IDC signal is linear or not. Post the results here.
